ANT build : Variable inside resolver:artifacts is undefined - build

Question

I have setup this ANT build.xml file which pulls in version info from a txt file , reads the first line, trims it and copies it into a variable called 'versionVal' with below code:
<target name="clean"
.
. do something more
.
<loadfile property="versionValTxt" srcfile="version.txt">
<filterchain>
<filterreader classname="org.apache.tools.ant.filters.HeadFilter">
<param name="lines" value="1" />
</filterreader>
</filterchain>
</loadfile>
<loadresource property="versionVal">
<propertyresource name="versionValTxt"/>
<filterchain>
<tokenfilter>
<filetokenizer/>
<replacestring from="V" to=""/>
</tokenfilter>
<striplinebreaks/>
</filterchain>
</loadresource>
<echo>"Building for version: ${versionVal}"</echo>
</target>
And in one of the targets I am trying to refer a resolver artifact which uses this versionVal to find a file with that specific version in its name as shown below:
<resolver:artifacts id="producedArtifacts" >
<resolver:artifact file="${dist.dir}/App.${versionVal}.zip"/>
</resolver:artifacts>
<target name="nexus">
<echo>"versionVal: ${versionVal}"</echo>
<resolver:deploy artifactsref="producedArtifacts">
<resolver:remoterepo refid="ossrh"/>
</resolver:deploy>
</target>
And the build keeps failing as below, where it shows the variable versionVal is undefined.
C:\Users\XYZ\git\App\WebContent\dist\App.${versionVal}.zip does not exist
Note that the block is able to recognize ${dist.dir} but it doesnt recognize ${versionVal}. However I am able to print the value using an echo inside the target-nexus.
Much appreciated if anyone can point me in the right direction. I am not able to figure out why this variable is not recognized under "resolver:artifact file" and if there are any alternatives to this problem.

Answer 1

Realised I had to include below resolver artifact inside a target block and then use that as depends in the nexus block. After making this change the variable 'versionVal' was recognized.
Solution:
<target name="packagedArtifact" >
<resolver:artifacts id="producedArtifacts" >
<resolver:artifact file="${dist.dir}/App.${versionVal}.zip"/>
</resolver:artifacts>
</target>
<target name="nexus" depends="packagedArtifact">
<resolver:deploy artifactsref="producedArtifacts">
<resolver:remoterepo refid="ossrh"/>
</resolver:deploy>
</target>
