Hi All,

I'm trying to run my junit tests using ant. The tests are kicked off using a JUnit 4 test suite. If I run this direct from Eclipse the tests complete without error. However if I run it from ant then many of the tests fail with this error repeated over and over until the junit task crashes.

    [junit] java.util.zip.ZipException: error in opening zip file

my test running task is as follows:

    <target name="run-junit-tests" depends="compile-tests,clean-results">
    	<mkdir dir="${test.results.dir}"/>
    	<junit failureproperty="tests.failed" fork="true" showoutput="yes" includeantruntime="false">
    		<classpath refid="test.run.path" />
    		<formatter type="xml" />
    		<test name="project.AllTests" todir="${basedir}/test-results" />
    	</junit>
    	<fail if="tests.failed" message="Unit tests failed"/>
    </target>

I've verified that the classpath contains the following as well as all of the program code and libraries:

ant-junit.jar
ant-launcher.jar
ant.jar
easymock.jar
easymockclassextension.jar
junit-4.4.jar

I've tried debugging to find out which ZipFile it is trying to open with no luck, I've tried toggling includeantruntime and fork and i've tried running ant with ant -lib test/libs where test/libs contains the ant and junit libraries.

Any info about what causes this exception or how you've configured ant to successfully run unit tests is gratefully received.

ant 1.7.1 (ubuntu), java 1.6.0_10, junit 4.4

Thanks.

Update - Fixed Found my problem. I had included my classes directory in my path using a fileset as opposed to a pathelement this was causing .class files to be opened as ZipFiles which of course threw an exception.
