Set working directory in <junit> Ant task

Question

Hi,

My Ant build includes a junit task that runs some tests. In order for the tests to work, the value of the property that specifies the current working directory (user.dir) must be changed, but I am unsure how to achieve this.

The task in question currently looks like this:

<junit printsummary="withOutAndErr" fork="true" haltonfailure="yes" showoutput="true" filtertrace="false" dir="C:/workspace/obp-web">
 <jvmarg value="-Duser.dir=C:/workspace/obp-web"/>

 <classpath>
  <fileset dir="${web.lib.dir}" includes="**/*.jar"/>
  <fileset dir="${lib.dir}" includes="**/*.jar"/>
 </classpath> 
 <batchtest fork="no" todir="${web.build.dir}/testresults">
  <formatter type="xml"/>
  <zipfileset src="${web.build.dir}/test-obp-web.jar">
   <include name="**/*Test.class"/>
  </zipfileset>   
 </batchtest>
</junit>

Notice that I've tried to use both the "dir" attribute and the "jvmarg" task to change the working directory to C:/workspace/obp-web. However when I run Ant with verbose output turned on, I see the following output, which indicates that the working dir has not been set correctly:

[junit] dir attribute ignored if running in the same VM

Thanks in advance, Don

Answer 1

Try using a jvmarg:

<junit>
  <jvmarg value="-Duser.dir=somedir"/>
  ...
</junit>

Note that fork must be true on both the junit tag and the batchtest tag as the batchtest tag overrides the value from junit. Jvmargs only work if junit forks a new JVM.

Answer 2

Use the attribute "dir" (must also fork the vm):

Answer 3

Have you tried pathelement location? This worked for me.

  <classpath>
<!-- filesets, etc. -->
<pathelement location="C:/workspace/obp-web" />
  </classpath>
