Hi
I am testing a little bit with Custom Runtime Images for our RCP
Application and want to share my experiences. Our custom image is
created by the following Ant snippet.
${gtbjdk.home} is the used JDK home directory and ${gtbjdk.dir} is the
destination folder name.
<loadresource property="jlink-modules">
<concat>
<union>
<string>java.desktop,</string>
<string>java.instrument,</string>
<string>java.logging,</string>
<string>java.naming,</string>
<string>jdk.localedata,</string>
<string>jdk.management,</string>
<string>jdk.pack,</string>
<string>jdk.jdwp.agent,</string><!-- only to be able to debug
the rcp app -->
</union>
</concat>
</loadresource>
<loadresource property="jlink-locales">
<concat>
<union>
<string>en,</string>
<string>de,</string>
<string>pt-BR,</string>
</union>
</concat>
</loadresource>
<exec executable="${gtbjdk.home}/bin/jlink${jlinkext}"
failonerror="true" if:set="dojlink">
<env key="JAVA_HOME" path="${gtbjdk.home}"/>
<arg value="--strip-debug"/>
<arg value="--no-header-files"/>
<arg value="--no-man-pages"/>
<arg value="--output"/>
<arg value="${temp.dir.rest}/${gtbjdk.dir}"/>
<arg value="--module-path"/>
<arg value="${gtbjdk.home}/jmods"/>
<arg value="--add-modules"/>
<arg value="${jlink-modules}"/>
<arg value="--include-locales=${jlink-locales}"/>
<!--<arg value="- -vm=server"/>-->
</exec>
<echo level="info" if:set="dojlink">Created JRE in
${temp.dir.rest}/${gtbjdk.dir}</echo>
The tasks are executed as dependecy of the "build-zip" target and after
"build-launchers". On Success the generated JRE-Path is set directly in
our app.conf:
<available file="${temp.dir.rest}/${gtbjdk.dir}"
property="gtbjre.exist"/>
<replace if:set="gtbjre.exist"
file="${build.launcher.dir}/etc/${app.name}.conf"
value="jdkhome=./${gtbjdk.dir}">
<contains text="#jdkhome"/>
<replacetoken><![CDATA[#jdkhome="/path/to/jdk"]]></replacetoken>
</replace>
The generated Runtime Image is about 64 MB from an Oracle JDK 9.0.4 (win64)
Greetings
Jens
