Bundling JRE in a feature [message #1720946] Fri, 22 January 2016 05:59 Go to next message

I've followed the instructions https://codeiseasy.wordpress.com/2012/07/31/including-a-jre-in-a-tycho-build/
to bundle JRE in a feature (not as a root file).
All works except file permissions in JRE are not retained during build on Mac.
As a workaround advised here:
https://dev.eclipse.org/mhonarc/lists/tycho-user/msg04632.html
I'm trying to use chmod touchpoint action to add execute bit to binaries inside JRE.

The problem is that I have no clue how to pass the location of a file to the chmod action. I've tried both native and eclipse action, passed @artifact and ${artifact.location} but none seems to be working.

Does anybody have any advice how to handle that?

Since it looks like nobody can answer this I'm going to share my solution.
What is working in setJvm and chmod touchpoint actions is ${installFolder} variable substitution.
So the path should be: ${installFolder}/features/featureid_featureversion/....
Now the problem is that $version$ substitution is not working as advertised. What I had to do is to use maven-resources-plugin to process p2.inf file with the following content (shown for Mac OS X):
instructions.configure=org.eclipse.equinox.p2.touchpoint.eclipse.setJvm(jvm:${installFolder}/features/[plarform_specific_jre_feature_id]_${qualifiedVersion}/jre/lib/jli/libjli.dylib);
instructions.install=org.eclipse.equinox.p2.touchpoint.eclipse.chmod(targetDir:${installFolder}/features/[plarform_specific_jre_feature_id]_${qualifiedVersion}/jre/lib,targetFile:jspawnhelper,permissions:755);
instructions.unconfigure=org.eclipse.equinox.p2.touchpoint.eclipse.setJvm(jvm:null);

Note setting jspawnhelper as executable - without that ProcessBuilder throws exception when trying to execute external process from Java program.

Hope that helps someone.

Which - as I've just seen - does not work in case of Oomph install.
Since Oomph installs features in bundle pools the path "${installFolder}/features/...." does not exist of course.

Any ideas anyone?

I think it should generally be "${bundlePool}/features/...". In standard "stand-alone" installations the install folder
*is* the bundle pool, so it should work in both cases with shared and with unshared bundle pool.

I tried to use ${bundlePool} but it seems it is not resolved inside Eclipse Target definition and I get the error that chmod failed because the path could not be found. Is this an error of the target editor or do I got something wrong?
instructions.install=org.eclipse.equinox.p2.touchpoint.eclipse.chmod(targetDir:${bundlePool}/features/<my feature name>/jre/bin,targetFile:java,permissions:755);

The P2 director/tycho also seem to not understand ${bunldePool} is there anything that must be set for this to work?

Did you ever find a resolution to this?
