Bug Description

eclipse-mylyn 3.12.0-2 fails to build from source in Zesty with the following error message:

/usr/lib/eclipse/dropins/sdk/plugins/org.eclipse.pde.build_3.8.1.dist/scripts/build.xml:35: The following error occurred while executing this line:
/usr/lib/eclipse/dropins/sdk/plugins/org.eclipse.pde.build_3.8.1.dist/scripts/build.xml:91: The following error occurred while executing this line:
/usr/lib/eclipse/dropins/sdk/plugins/org.eclipse.pde.build_3.8.1.dist/templates/package-build/customTargets.xml:19: The following error occurred while executing this line:
/usr/lib/eclipse/dropins/sdk/plugins/org.eclipse.pde.build_3.8.1.dist/scripts/genericTargets.xml:111: Processing inclusion from feature org.eclipse.mylyn.commons: Unable to find plug-in: org.apache.commons.lang_0.0.0. Please check the error log for more details.

See for complete build log.

I got the same error message when attempting to build the package on my Zesty vm, but didn't have any problems on Debian Sid. When I saw that the package containing commons-lang mentioned in the error message had an Ubuntu-delta, I wanted to check if this could explain the different results.

I downloaded libcommons-lang-java from Debian and installed it on my Zesty vm. With this package, eclipse-mylyn built successfully. I therefore believe the Ubuntu-delta or a difference in how libcommons-lang-java has been built is causing this issue.

(I've also seen that and have failed to build with similar error messages, but I don't know for certain if this is related or not.)

Checked back on this and it is still present in Artful. Furthermore, I discovered that attempting to rebuild the current version of eclipse-mylyn will also fail.

It looks like the libcommons-lang-java delta was introduced while it was part of main. It seems to have been demoted to universe a couple of releases ago, so I wonder whether the delta is still required?
