take liquibase scripts not from resource folder during unit tests - unit-testing

Question

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.
