    <p>Had a problem with retrieving returncode programmatically...following files. (did cut out some company-specific things). I got 2 files, one general file with a java-task in it and a specific file, which defines sime properties and a ant-task. </p> <p>How can i get the build.rc in my executing java-test? The echo-message at the end of the file delivers the actual return-code, but the p.getProperty("build.rc") returns null. </p> <p><strong>specific.build.xml</strong> </p> <pre><code>&lt;project basedir="../../../.." name="run-joblauncher"&gt; &lt;property name="prop1" value="valProp1" /&gt; &lt;ant antfile="./dev/script/general.xml" dir="${basedir}" target="RUN-MYCLASS" inheritAll="true"/&gt; &lt;/project&gt; </code></pre> <p><strong>general.xml</strong></p> <pre><code>&lt;project basedir="../../../.." default="RUN-MYCLASS" name="run-specifictest"&gt; &lt;target name="RUN-MYCLASS"&gt; &lt;property name="returnCode" value="99"/&gt; &lt;target name="RUN-MYCLASS"&gt; &lt;java classname="my.company.class" fork="true" resultproperty="build.rc" failonerror="false"&gt; &lt;arg value="${workdir}"/&gt; &lt;classpath&gt; &lt;pathelement path="${java.class.path}"/&gt; &lt;/classpath&gt; &lt;/java&gt; &lt;/target&gt; &lt;/project&gt; </code></pre> <p><strong>myJunitTest.java</strong></p> <pre><code>public class TestAntScripts extends TestCase { public void testMyAnt() throws IOException { File dir = new File("pathToSpecific.xml"); Project p = null; try { File buildFile = new File(buildFileName); p = new Project(); DefaultLogger consoleLogger = new DefaultLogger(); consoleLogger.setErrorPrintStream(System.err); consoleLogger.setOutputPrintStream(System.out); consoleLogger.setMessageOutputLevel(Project.MSG_INFO); p.addBuildListener(consoleLogger); p.addBuildListener(new CustomBuildListener(this)); p.fireBuildStarted(); p.init(); ProjectHelper helper = ProjectHelper.getProjectHelper(); p.addReference("ant.projectHelper", helper); helper.parse(p, buildFile); p.fireBuildFinished(null); } catch (BuildException e) { p.fireBuildFinished(e); e.printStackTrace(); System.err.println("AntRunner for buildfile " + buildFileName + " failed with Exception "); } String rc = p.getProperty("returnCode"); assertEquals(0, Integer.parseInt(rc)); } public void taskFinished(String buildRc) { assertEquals(0, buildRc); } } </code></pre> <p><strong>EDIT:</strong> </p> <p>how's the approach to assign a value to a already defined property? defined a var returnCode outside the java-target and try to assign the value like <code>&lt;var name="returnCode" value="${build.rc}"/&gt;</code> inside the target. not runnin'..</p> <p><strong>EDIT2:</strong> added a custom BuildListener and grabbing the build.rc over there. </p> <pre><code> @Override public void targetFinished(BuildEvent event) { if (event.getTarget().getName().trim().equalsIgnoreCase("RUN-MYCLASS")) { String buildRc = event.getTarget().getProject().getProperty("build.rc"); tester.taskFinished(buildRc, jobname); } </code></pre> <p>tester is my JUnit-Test, which will be set in Constructor.</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.

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