How the platform releng team incorporated pack200 technology into our build process?

During our build process, we build a giant feature that includes all the jars that are required by the build, with the exception of ones required by the test features. Here is an except from the script that runs the process...

(Example is from org.eclipse.releng.eclipsebuilder/buildAll.xml v20060426a)

<target name="main" depends="init"> <antcall target="buildEclipseSourceDrops" /> <antcall target="buildMasterFeature" /> <parallel failonany="true"> <sequential> <antcall target="signMasterFeature" /> <antcall target="unpackUpdateJarsForPackaging" /> <antcall target="buildUpdateSite" /> </sequential> <sequential> <antcall target="buildMasterRootFeature" /> <antcall target="buildSdkTestFeature" /> <ant antfile="${eclipse.build.configs}/../helper.xml" target="verifyCompile" /> </sequential> </parallel> <parallel failonany="true"> <sequential> <antcall target="packageEclipseDistributables" /> <antcall target="packageEquinoxDistributables" /> <antcall target="publishEclipse" /> <antcall target="publishEquinox" /> </sequential> <antcall target="testEclipse" /> </parallel> </target>


The target signMasterFeature below currently just packs the master feature. (The signing portion will probably not be in place for 3.2 because there isn't enough time for other teams to adapt).

<target name="signMasterFeature" if="sign"> <property name="archiveName" value="eclipse-master-${buildId}.zip" /> <property name="packtmp" value="${buildDirectory}/packtmp" /> <mkdir dir="${packtmp}" /> <move file="${buildDirectory}/${buildLabel}/${archiveName}" tofile="${packtmp}/${archiveName}"/>

<java jar="${eclipse.home}/startup.jar" fork="true"

       	   jvm="${java15-home}/bin/java"

failonerror="true" maxmemory="128m" dir="${buildDirectory}"> <arg line="-application org.eclipse.update.core.siteOptimizer"/> <arg line="-jarProcessor -outputDir ${buildLabel} -repack ${packtmp}/${archiveName}"/> </java>

<delete dir="${packtmp}" /> </target>


The unpackUpdateJarsForPackaging task unpacks the jars with unpack=false in their features.

We then build an update site with the
