Question

I’m developing an Eclipse SWT application using Eclipse. There are also some JUnit 4 tests, which test some DAO’s. But when I try to run the tests via an ant build, all of the tests fail, because the test classes aren’t found.

Google brought up about a million of people who all have the same problem, but none of their solutions seem to work for me -.- .

These are the contents of my build.xml file:

<property name="test.reports" value="./test/reports" />
<property name="classes" value="build" />


<path id="project.classpath">
    <pathelement location="${classes}" />
</path>

<target name="testreport">
    <mkdir dir="${test.reports}" />
    <junit fork="yes" printsummary="no" haltonfailure="no">
        <batchtest fork="yes" todir="${test.reports}" >
            <fileset dir="${classes}">
                <include name="**/Test*.class" />
            </fileset>
        </batchtest>
        <formatter type="xml" />

        <classpath refid="project.classpath" />


    </junit>

    <junitreport todir="${test.reports}">
        <fileset dir="${test.reports}">
            <include name="TEST-*.xml" />
        </fileset>
        <report todir="${test.reports}" />
    </junitreport>
</target>

The test classes are in the build-directory together with the application classes, although they are in some subfolders according to their packages.

Maybe this is important too: At first Ant complained that JUnit wasn’t in its classpath, but since I put it there (with the eclipse configuration editor) it complains about JUnit being in its classpath twice.

WARNING: multiple versions of ant detected in path for junit 
   [junit]          jar:file:C:/Users/as df/Documents/eclipse/plugins/org.apache.ant_1.7.1.v20090120-1145/lib/ant.jar!/org/apache/tools/ant/Project.class

I’ve tried specifying each and every subdirectory, each and every class file, I’ve tried filesets and filelists, nothing seems to work.

Thanks for your help, I’ve been sitting for hours on this thing now…

Answer 1

I had the same problem ‘multiple versions of ant detected in path for junit’. The problem went away when I renamed by Eclipse_Home directory and removed special characters from it. The path had ‘[1]’ in it which was causing the problem.
