    <p>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.</p> <pre> [junit] java.util.zip.ZipException: error in opening zip file [junit] at java.util.zip.ZipFile.open(Native Method) [junit] at java.util.zip.ZipFile.(ZipFile.java:114) [junit] at java.util.zip.ZipFile.(ZipFile.java:131) [junit] at org.apache.tools.ant.AntClassLoader.getResourceURL(AntClassLoader.java:1028) [junit] at org.apache.tools.ant.AntClassLoader$ResourceEnumeration.findNextResource(AntClassLoader.java:147) [junit] at org.apache.tools.ant.AntClassLoader$ResourceEnumeration.nextElement(AntClassLoader.java:130) [junit] at org.apache.tools.ant.util.CollectionUtils$CompoundEnumeration.nextElement(CollectionUtils.java:198) [junit] at sun.misc.CompoundEnumeration.nextElement(CompoundEnumeration.java:43) [junit] at org.apache.tools.ant.taskdefs.optional.junit.JUnitTask.checkForkedPath(JUnitTask.java:1128) [junit] at org.apache.tools.ant.taskdefs.optional.junit.JUnitTask.executeAsForked(JUnitTask.java:1013) [junit] at org.apache.tools.ant.taskdefs.optional.junit.JUnitTask.execute(JUnitTask.java:834) [junit] at org.apache.tools.ant.taskdefs.optional.junit.JUnitTask.executeOrQueue(JUnitTask.java:1785) [junit] at org.apache.tools.ant.taskdefs.optional.junit.JUnitTask.execute(JUnitTask.java:785) [junit] at org.apache.tools.ant.UnknownElement.execute(UnknownElement.java:288) [junit] at sun.reflect.GeneratedMethodAccessor1.invoke(Unknown Source) [junit] at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) [junit] at java.lang.reflect.Method.invoke(Method.java:597) [junit] at org.apache.tools.ant.dispatch.DispatchUtils.execute(DispatchUtils.java:106) [junit] at org.apache.tools.ant.Task.perform(Task.java:348) [junit] at org.apache.tools.ant.Target.execute(Target.java:357) [junit] at org.apache.tools.ant.Target.performTasks(Target.java:385) [junit] at org.apache.tools.ant.Project.executeSortedTargets(Project.java:1337) [junit] at org.apache.tools.ant.Project.executeTarget(Project.java:1306) [junit] at org.apache.tools.ant.helper.DefaultExecutor.executeTargets(DefaultExecutor.java:41) [junit] at org.apache.tools.ant.Project.executeTargets(Project.java:1189) [junit] at org.apache.tools.ant.Main.runBuild(Main.java:758) [junit] at org.apache.tools.ant.Main.startAnt(Main.java:217) [junit] at org.apache.tools.ant.launch.Launcher.run(Launcher.java:257) [junit] at org.apache.tools.ant.launch.Launcher.main(Launcher.java:104) </pre> <p>my test running task is as follows:</p> <pre> &lt;target name=&quot;run-junit-tests&quot; depends=&quot;compile-tests,clean-results&quot;&gt; &lt;mkdir dir=&quot;${test.results.dir}&quot;/&gt; &lt;junit failureproperty=&quot;tests.failed&quot; fork=&quot;true&quot; showoutput=&quot;yes&quot; includeantruntime=&quot;false&quot;&gt; &lt;classpath refid=&quot;test.run.path&quot; /&gt; &lt;formatter type=&quot;xml&quot; /&gt; &lt;test name=&quot;project.AllTests&quot; todir=&quot;${basedir}/test-results&quot; /&gt; &lt;/junit&gt; &lt;fail if=&quot;tests.failed&quot; message=&quot;Unit tests failed&quot;/&gt; &lt;/target&gt; </pre> <p>I've verified that the classpath contains the following as well as all of the program code and libraries:</p> <pre> ant-junit.jar ant-launcher.jar ant.jar easymock.jar easymockclassextension.jar junit-4.4.jar</pre> <p>I've tried debugging to find out which ZipFile it is trying to open with no luck, I've tried toggling <i>includeantruntime</i> and <i>fork</i> and i've tried running ant with <i>ant -lib test/libs</i> where test/libs contains the ant and junit libraries.</p> <p>Any info about what causes this exception or how you've configured ant to successfully run unit tests is gratefully received.</p> <p>ant 1.7.1 (ubuntu), java 1.6.0_10, junit 4.4</p> <p>Thanks.</p> <p><strong>Update - Fixed</strong> 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.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
