Question

I’m running an ant build file that creates a Jar. The task looks like this:

<target name="generator-app" depends="clean,compile">
    <jar jarfile="${gen.App}">
       <manifest>
       ...
       </manifest>
       <fileset dir="${classes}">
          <include name="com/mypackage/**" />
       </fileset>
       <zipfileset dir="${jars}" />
     </jar>
</target>

The build file runs and creates the file as expected when I run it on Linux, but fails with this error on any other platform:

BUILD FAILED /home/user/build.xml:287: the archive doesn't exist

I tried using destfile instead of jarfile, but the same result occurs. The archive does not exist indeed, but the purpose of the task is to create it.

Is there any limitation on certain platforms or any way to correct this?

Answer 1

I found the problem. I tried using a newer version of ant, and now the error indicates exactly what is missing (a jar to be packaged in the jar to be created).
