    <p>I've a requirement where I have to extract metrics from different Java projects (configured in Eclipse) through <a href="http://metrics.sourceforge.net/" rel="nofollow noreferrer">Metrics Plugin</a>. I am trying to automate this process using ANT build scripts.</p> <p>I've made a Java utility project that will:</p> <ol> <li>Create these build files</li> <li>Put them in respective Java projects configured in Eclipse</li> <li>Attempt to execute them.</li> </ol> <p>While the build.xml are running correctly, when I try to run them programmatically, I get the following error:</p> <pre><code>Exception in thread "main" ProjectHelper.parse() must be implemented in a helper plugin org.apache.tools.ant.ProjectHelper at org.apache.tools.ant.ProjectHelper.parse(ProjectHelper.java:277) at com.metrics.generator.MetricsGenerator.runAntScripts(MetricsGenerator.java:69) at com.metrics.generator.MetricsGenerator.doAutomate(MetricsGenerator.java:43) at com.metrics.generator.MetricsGenerator.main(MetricsGenerator.java:30) </code></pre> <p>I am assuming that the parse() method is not working correctly, but I don't understand why. Running the build.xml manually works (which means that the XML file is correctly created). The only modification that I had to make for Eclipse to run this build was to go to Run > External Tools > External Tools Configuration > JRE and select "Run in the same JRE as the workspace"</p> <p>The build file is as follows:</p> <pre><code>&lt;project basedir="." default="init" name="projectName"&gt; &lt;target name="init"&gt; &lt;tstamp/&gt; &lt;/target&gt; &lt;target depends="init" name="build"&gt; &lt;eclipse.refreshLocal depth="infinite" resource="projectName"/&gt; &lt;metrics.enable projectName="projectName"/&gt; &lt;eclipse.build BuildType="full" ProjectName="projectName" errorFormat="xml" errorOut="errors.xml" failOnError="true"/&gt; &lt;metrics.export file="outputFile" projectName="projectName"/&gt; &lt;/target&gt; &lt;/project&gt; </code></pre> <p>Note: [projectName] and [ouputFile] are currently provided at the time of their creation, I just omitted them from this post. FYI, I'm using Eclipse Indigo. The code where it fails looks as follows:</p> <pre><code>private void runAntScripts(File[] projectFolders){ BuildLogger logger = new DefaultLogger(); logger.setOutputPrintStream(System.out); logger.setErrorPrintStream(System.out); logger.setMessageOutputLevel(Project.MSG_INFO); Project metricsProject = new Project(); metricsProject.addBuildListener(logger); ProjectHelper helper = new ProjectHelper(); metricsProject.addReference("ant.projectHelper", helper); File buildFile; int totalFolders = projectFolders.length; for(int index = 0; index &lt; totalFolders; index++){ buildFile = new File(projectFolders[index], buildXMLFileName); if(buildFile.isFile()){ helper.parse(metricsProject, buildFile); metricsProject.setProperty("ant.file", buildFile.getAbsolutePath()); metricsProject.init(); metricsProject.setBaseDir(projectFolders[index]); metricsProject.executeTarget("build"); } } } </code></pre>

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).
