A single ant task that will subject your code to junit, emma, findbugs, checkstyle, pmd, jDepend, TestabilityExplorer & javaNcss without all the fuss of setting up each of these tools.

Usage:

<target name="analyze" depends="compile">
 
   <!-- define the task set -->
   <property name="jar.name" value="jAnalysisSuite-{latest}.jar">
   <taskdef resource="staticanalysis.properties" classpath="${jar.name}"/>               
   <setupAnalysis jar="${jar.name}" quiet="true"/>
 
   <!-- add individual parts of the project to the batch -->
   <!-- do this as many times as you want for each of the different -->
   <!-- modules you wish to analyze                          -->
   <addAnalysisItem srcdir="${src.dir}"  builddir="${classes.dir}"/>
   <addanalysisitem srcdir="${src2.dir}" builddir="${classes2.dir}">
   <addanalysisitem srcdir="${src3.dir}" builddir="${classes3.dir}" testdir="${unittest.dir}">
 
	        <performStaticAnalysis  todir="reports" basename="report_">
	        	<checkstyle/>
	        	<cpd/>
	        	<jdepend />
	        	<testabilityexplorer />
	        	<pmd/>
                        <javancss/>
	        	<findbugs />
	        	<emma filter="com.peterfranza.*"/>

	        </performStaticAnalysis>
 
</target>
