Hello,
I'm trying to build some Eclipse plugins using PDE and Maven (migration to
Maven). The compiler used is the Eclipse Compiler (ECJ) and the version is
the same for both: 3.4.0.v_874. The source/target levels are the same, 1.5,
the dependencies are the same, yet some of the compiled files are not
equivalent (not even in size). Example: ToolBarManager.class built with
Maven: 6.4KB, built with PDE: 7.1KB. That's almost 0.8KB worth of
"optimizations"?!?
Does anyone here have experience with Maven and with PDE, maybe I'm missing
something in the configuration of Maven (I want to replicate the PDE output
with Maven).
For reference, the PDE execution command, and the Maven compile
configuration:
1. PDE
<target name="build">
<property name="dir.runLocation"
value="${dir.finalBuildDir}"></property>
<property name="dir.baseLocation"
value="${dir.runLocation}/base"></property>
<property name="dir.buildDir"
value="${dir.runLocation}/builder"></property>
<echo>{dir.buildDir} = ${dir.runLocation} </echo>
<echo>{dir.location}=${dir.buildDir}</echo>
<exec executable="java" failonerror="true">
<!-- starting eclipse ant Runner -->
<arg value="-jar"/>
<arg
value="${dir.runLocation}/base/eclipse/plugins/${eclipse.equinox.launcher}"/>
<arg value="-application"/>
<arg value="org.eclipse.ant.core.antRunner"/>
<arg value="-buildfile"/>
<arg

<!-- argumenst for the script provided by eclipse
-->
<!-- name for the location of the build.properties
files -->
<arg value="-Dbuilder=${dir.runLocation}\builder"/>
<!-- name for the base location where the eclipse
used in the build is -->
<arg

<!-- skip downloading eclipse, allready downloaded

<arg value="-DskipBase=true"/>
<!-- target platform and operating system -->
<arg

<!-- build directory where we provide the structure
required by the pde build -->
<arg value="-DbuildDirectory=${dir.runLocation}"/>

<arg value="-DjavacSource=1.5"/>
<arg value="-DjavacTarget=1.5"/>
<!-- location for the scripts in eclipse -->
<arg value="-DrootDir=${dir.runLocation}" />
<arg
value="-Declipse.pdebuild.scripts=${dir.baseLocation}\eclipse\plugins\${eclipse.pde.build}\scripts"/>
<!-- main feature declaration -->
<arg value="-DmainFeature=${build.feature}"/>
<!-- location of the product file, for the current
application -->
<arg
value="-Dproduct=${dir.runLocation}\features\${build.feature}\${build.feature.product}"/>
<!-- directory for the build -->
<arg
value="-DbuildLabel=${build.label.prefix}-${timestamp}"/>
<!-- label for the final zip -->
<arg
value="-DbuildId=${build.id.prefix}-${timestamp}"/>
<arg value="-DbuildType=${build.release.type}"/>
<arg
value="-DbuildVersion=${build.release.version}"/>
</exec>
</target>
