I have different projects and each project on a folder and each project have a unique build.xml file.
example
There is a main folder and under that 3 different folders called A,B and C.
inside each A,B and C folders there is a unique build.xml file.
Are there any way to execute all these 3 build.xml files from apache ant by using a common build.xml?
If possible how to do that?
This is the basic purpose of the <ant> task. The manual page contains many examples and options: https://ant.apache.org/manual/Tasks/ant.html
E.g.
<target name="build-subprojects">
<ant antfile="subproject1/build.xml"/>
<ant antfile="subproject2/build.xml"/>
</target>

I have a following project structure
bin
start.sh
db
liquibase_scripts
...
schema.json
main
java
...
test
resources
liquibase_scripts
...
schema.json
So than I build my project, folder db with liquibase scripts added to distributive.
In unit tests I use H2 database and want to load schema from db/liquibase. I create bean
#Bean
public SpringLiquibase springLiquibase() {
SpringLiquibase springLiquibase = new SpringLiquibase();
springLiquibase.setDataSource(dataSource());
springLiquibase.setChangeLog("classpath:/liquibase/sam.json");
return springLiquibase;
}
The problem is that method setChangeLog look at resource folder in test folder.
So to solve the problem I copied all liquibase scripts to the test/resources directory.
But this is not ok becouse now I have 2 copies of scripts in different folders.
Is there a way to force springLiquibase.setChangeLog find scripts in any folder not only in test/resources?
In Maven build configuration you can define testResources, which may be directories and files. It looks like this:
<build>
<testResources>
<testResource>
<directory>${project.basedir}/db/liquibase_scripts</directory>
</testResource>
</testResources>
</build>
With such configuration Maven copies the files into the target/test-classes directory. Thanks to that those files can be used as test resources in the code, but there's no duplication in the project files.
Im using such configuration (Liquibase + testResources) in one of my projects. To better reproduce your problem, I've created a separate branch, where you can find the configuration described above - see: this commit diff. All test pass after the change.
I am working differentially building a huge monolithic solution that includes about 80 projects. In my build pipeline right now I include a step to build the entire solution. But what I'd like to do is to build the solution but provide conditions as msbuild arguments so that I can exclude some of the projects that might not have any changes associated with them. I already have scripts to go through my commits and realize what changed and which projects need to be built.
I just need a way to send that info to MSBuild so that it does not build all projects everytime. I tried building projects separately but that takes a whole lot more time than just building the solution together.
So, I'm looking for any solutions out there through which I can specify to MSBuild that skip a specific project would help a lot. Thanks much!
I already have scripts to go through my commits and realize what
changed and which projects need to be built.
Since I could get clearly know that which script are you using to realize what changed and which projects need to be built. I am assuming that you are using MSbuildTarget script which in the xx.csproj to do these judgement.
=If I did not have misunderstanding, you can get help from this similar issue (See ilya's answer).
See this document and you'll find the build action is performed by these three targets, BeforeBuild,CoreBuild and AfterBuild. So assuming you have a target to go through my commits and realize what changed and if a project need to be built, you can add script like below to xx.csproj:
<PropertyGroup>
<BuildWrapperDependsOn>$(BuildDependsOn)</BuildWrapperDependsOn>
<BuildDependsOn>CheckIfBuildIsNeeded;BuildWrapper</BuildDependsOn>
</PropertyGroup>
<Target Name="CheckIfBuildIsNeeded">
<!-- Execute command here that checks if proceed with the build and sets the exit code -->
<Exec Command="exit /b 1" WorkingDirectory="$(SourcesPath)" IgnoreExitCode="true">
<Output TaskParameter="ExitCode" PropertyName="ExecExitCode"/>
</Exec>
<Message Text="Exit Code: $(ExecExitCode)" Importance="high" />
<PropertyGroup Condition="'$(ExecExitCode)' == '1'">
<DoBuild>false</DoBuild>
</PropertyGroup>
</Target>
<Target Name="BuildWrapper" Condition=" '$(DoBuild)' != 'false' " DependsOnTargets="$(BuildWrapperDependsOn)" Returns="$(TargetPath)" />
Above is the script from ilys, and hope my description can help you understand it. With this script, when we start a build target, it will firstly run the targets it depends on, so it will run the CheckIfBuildIsNeeded target and BuildWrapper target. And only when the DoBuild property is true, the BuildWrapper will actually execute. And since buildwrapper depends on original $(BuildDependsOn), it will continue the real build process.
The total logic is: Run CheckIfBuildIsNeeded script and output value to indicates whether need to build=>Try to Run BuildWrapper=>IF need to build, then run the real build success(BeforeBuild, Corebuild,Afterbuild), if the value is false, finish the build process. So I think you can do some little changes to this script then it can work for your situation. (Not sure what your script looks like, I can't complete it for you)
And since you have many projects, you don't need to add this script to every project manually. You can create a Directory.Build.props file, copy the script into it, and place the file in solution folder, then it will work for all projects in the solution.
I have solution with n csharp projects and cpp project on top, this cpp provides interfaces and headers so those csharp ones can be used in other cpp solutions.
The build machine is configured to build csharp project with anyCPU architecture so it provides single assembly per build in Solution\bin\Release. For cpp the anyCpu is not available so I build project twice and store assemblies in Solution\bin\Release\x86 and x64 folders.
This is all to get it packaged in nuget as a single package with .targets file to ease consumption in other cpp projects.
Issue is that cpp project is looking for csharp asseblies using ResolveAssemblyReference and cannot find it, giving missleading message:
ResolveAssemblyReferences:
Primary reference "Implementation".
Could not find dependent files. Expected file "C:\Jenkins\Workspace\Solution\bin\Release\x86\Implementation.dll" does not exist.
Could not find dependent files. Expected file "C:\Jenkins\Workspace\Solution\bin\Release\x86\Implementation.dll" does not exist.
Resolved file path is "C:\Jenkins\Workspace\Solution\bin\Release\x86\Implementation.dll".
Reference found at search path location "".
I tried to alternate ResolveAssemblyReferences behaviour using command line properties, custom targets/properties, but without any luck. The parameters described in https://learn.microsoft.com/en-us/visualstudio/msbuild/resolveassemblyreference-task?view=vs-2017 seem to be computed during the build process and I cannot inject any value, which should be in this case something like $(OutDir)..
The one feasable solution seems to be copy c# dlls into each cpp folder, but I dont think it is the way to solve it properly.
Closes I got is by using /p:ReferencePath like below:
"C:\Program Files (x86)\Microsoft Visual Studio\2017\BuildTools\MsBuild\15.0\bin\MsBuild.exe" /p:BuildProjectReferences=false /p:Configuration=Release /p:DebugType=full /p:DebugSymbols=true /p:PlatformToolset=v120 /p:WindowsTargetPlatformVersion=8.1 /p:ForceImportBeforeCppTargets="C:\Jenkins\Workspace\Solution\Cpp.props" /p:OutDir="C:\Jenkins\Workspace\Solution\bin\Release\x86\" /p:Platform=Win32 /t:Build Interface\Interface.vcxproj /p:ReferencePath="C:\jenkins\workspace\Solution\bin\Release"
My custom Cpp.props does:
<Target Name="Output" BeforeTargets="ResolveAssemblyReferences">
<Message Text="AssemblySearchPaths: $(AssemblySearchPaths)" />
</Target>
and by adding /p:ReferencePath it got added to AssemblySearchPaths as second record, after {CandidateAssemblyFiles}; but it is still not finding those dlls
I'm managing a C++ project in VS2010 and want to have ALL .cpp files run through an external tool before going to the C++ compiler. All signs seem to indicate this is possible. See, for example, here.
Since this will happen over multiple projects, it makes sense to put this functionality in a property sheet and then just importing this property sheet everywhere. Before I touched the property sheet, it looked like this in its entirety:
<?xml version="1.0" encoding="utf-8"?>
<Project DefaultTargets="Build" ToolsVersion="4.0" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
<PropertyGroup>
<_ProjectFileVersion>10.0.30319.1</_ProjectFileVersion>
<ExtensionsToDeleteOnClean>...</ExtensionsToDeleteOnClean>
<CustomBuildBeforeTargets>ClCompile</CustomBuildBeforeTargets>
</PropertyGroup>
<ItemDefinitionGroup>
<ClCompile>
<AdditionalIncludeDirectories>...</AdditionalIncludeDirectories>
<ForcedIncludeFiles>%(ForcedIncludeFiles)</ForcedIncludeFiles>
</ClCompile>
<Link>
<AdditionalDependencies>...</AdditionalDependencies>
</Link>
<Outputs>...</Outputs>
</CustomBuildStep>
</ItemDefinitionGroup>
</Project>
As per the above linked document, I have added the following lines:
<Project>
<PropertyGroup>
...
<CustomBuildBeforeTargets>ClCompile</CustomBuildBeforeTargets>
</PropertyGroup>
...
<ItemGroup>
<CustomBuild Include="*.cpp">
<Message>Running Custom Build Step</Message>
<Command>dummy</Command>
<Outputs>dummy</Outputs>
</CustomBuild>
</ItemGroup>
</Project>
This appears to have no effect, and my custom build tool never runs before ClCompile. I have tried various ways of moving things around and renaming tags (the Xml editor complains that CustomBuild isn't even valid according to the schema, for example), but nothing works.
What am I doing wrong?
Although this is a very old question, I will attempt to answer it.
The Include attribute expects to find *.cpp files in the Project directory. If there are no .cpp files in the Project directory, then this CustomBuild "Task" will never kick in.
What the OP could have done was
<CustomBuild Include="**\*.cpp">
<Message>Custombuild kicking in</Message>
<Command>echo %(Identity)</Command>
<Outputs>dummy</Outputs>
</CustomBuild>
instead of
<CustomBuild Include="*.cpp">
...
and he would have performed the CustomBuild action on all the .cpp files in all the subdirectories of the project directory, and not just the .cpp files waiting to be compiled.
If the .cpp files are not availble under the Project directory (can happen when such a project directory structure is used) then the OP must explicitly point to the right "root" directory.
Alternatively you can save yourself wildcard usage by simply running an Exec task on every included ClCompile.
<Target Name="ProcessClCompileFiles" BeforeTargets="ClCompile" Condition="'#(ClCompile)'!=''">
<Message Text="== Starting processing cpp files ==" Importance="High"/>
<Exec Command="echo processing %(ClCompile.filename)%(ClCompile.extension) & ////YOUR COMMAND HERE////" />
</Target>
As a note. This requires the ClCompile itemgroup to be initialised before this Target. if you were to create a target that dynamically adds ClCompile, you'd have to ensure that this happens before this Target is called.
Another note is that these Exec tasks will always run if there are any items in the ClCompile itemgroup. If you have a condition where it should skip them (eg, already processed), use Condition="A=B"
For easy reference, here's how to validate it hasn't created a file and if it created a file; if the file is out of date:
Condition="!Exists('$(OutDir)%(Filename)%(Extension)') OR ($([System.DateTime]::Parse('%(ClCompile.ModifiedTime)').Ticks) > $([System.IO.File]::GetLastWriteTime('$(OutDir)%(Filename)%(Extension)').Ticks))"
I've read about the use of "Custom.Before.Microsoft.Common.targets" and "Custom.After.Microsoft.Common.targets" in order to execute a custom target before/after every project build and I would like to use this technique in order to change version info while building on our TeamCity build server.
The problem is that although it works for C# projects, it doesn't seem to work for native C++ projects.
After some digging around in the Microsoft.Cpp.targets file I found out that for native C++ projects this seems to be implemented through setting $(ForceImportBeforeCppTargets) and $(ForceImportAfterCppTargets).
I can't seem to find a single piece of information on the web about this technique for native C++ apps though, so I'm asking if I'm looking in the right direction or not.
Any help is appreciated.
For VC++ projects it is a bit different. You define a file to be imported either at the beginning or at the end of the project. To use this approach you need to define values for the properties ForceImportBeforeCppTargets or ForceImportAfterCppTargets. For example if you want a file to be included at the beginning of the project you can pass in the value at the command line. For example I just created a dummy VC++ project named CppTets01. Then I created the two sample files below.
Before.proj
<?xml version="1.0" encoding="utf-8"?>
<Project ToolsVersion="4.0" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
<Target Name="CustomTargetInBefore" AfterTargets="Build">
<Message Text="From CustomTargetInBefore" Importance="high"/>
</Target>
</Project>
After.proj
<?xml version="1.0" encoding="utf-8"?>
<Project ToolsVersion="4.0" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
<Target Name="CustomTargetInAfter" AfterTargets="Build">
<Message Text="From CustomTargetInAfter" Importance="high"/>
</Target>
</Project>
Then I executed the following command:
msbuild CppTest01.vcxproj
/p:ForceImportBeforeCppTargets="C:\Temp\_NET\ThrowAway\CppTest01\CppTest01\Before.proj";
ForceImportAfterCppTargets="C:\Temp\_NET\ThrowAway\CppTest01\CppTest01\After.proj"
The result was
C:\Temp_NET\ThrowAway\CppTest01\CppTest01>msbuild CppTest01.vcxproj /p:ForceImportBeforeCppTargets="C:\Temp_NET\ThrowAway\CppTest01\C
ppTest01\Before.proj";ForceImportAfterCppTargets="C:\Temp_NET\ThrowAway\CppTest01\CppTest01\After.proj"

As you can see from the output the targets were successfully injected into the build process. If you want to relate this back to Custom.Before.Microsoft.Common.targets and Custom.Before.Microsoft.Common.targets then you should know that the technique used there is a bit different. Specifically if you create those files they are automatically imported into every C#/VB.NET project. In this case you have to set this property. You really have two options here:
You can set this property as an environment variable
You can use another technique, ImportBefore & ImportAfter which is specific to VC++
For #1 let me explain a bit. In MSBuild when you access a property with the syntax $(PropName) then if a property with the name PropName doesn't exist MSBuild will look up in the environment variables to see if such a value exists, if it does then that value is returned. So if you have a build server in which you want to include a file for each VC++ build, then just create those properties as environment variables. Now for the other technique.
ImportBefore/ImportAfter
In VC++ a new concept is introduced. In Microsoft.Cpp.Win32.targets you can see the declaration at the top of the .targets file.
<Import Project="$(VCTargetsPath)\Platforms\Win32\ImportBefore\*.targets"
Condition="Exists('$(VCTargetsPath)\Platforms\Win32\ImportBefore')" />
Then there is one towards the bottom
<Import Project="$(VCTargetsPath)\Platforms\Win32\ImportAfter\*.targets"
Condition="Exists('$(VCTargetsPath)\Platforms\Win32\ImportAfter')" />
A similar import declaration exists for the other target platforms as well. Take a look at the files at %ProgramFiles32%\MSBuild\Microsoft.Cpp\v4.0\Platforms\ for the specific names.
With this technique if you want a file to be imported then simply create a file that ends with .targets and place it into the appropriate folder. The advantage of this is that it will be imported into every VC++ build for that platform, and that you can create many different files. The drawback is that you have to place them in those specific folders. That's the main difference between both techniques. With this first technique you can specify the file location via property and its not automatically included for every build, but for the second approach it is but you cannot change the location
You can also add project content into one of *.props files from directory %LOCALAPPDATA%\Microsoft\MSBuild\v4.0\
It make same effect.
