Hi,
I'm trying to use the asMaven plugin for several modeling tools (org.eclipse.qvt, org.eclipse.ocl, org.eclipse.xtend). When I run gradle I get the following error message: Unable to find: Installable Unit [ id=org.eclipse.ocl ]
I tried to verify the existence of the IUs via p2Director and each IU can be found.

/Applications/Eclipse_4.6/Eclipse.app/Contents/MacOS/eclipse -application org.eclipse.equinox.p2.director -repository http://download.eclipse.org/releases/neon -list 'Q:everything.select(x|x.id == "org.eclipse.ocl")' org.eclipse.ocl=3.6.0.v20160523-1914

When I try the dependencies in the examples (e.g. org.eclipse.text) it works. Am I missing something?

My build.gradle looks like this:

plugins {
    id 'com.diffplug.gradle.p2.asmaven' version '3.0.6'
}
apply plugin: 'java'

p2AsMaven {
    group 'eclipse-deps', {
        repoEclipse '4.6'
        iu          'org.eclipse.xtend'
    }
}

dependencies {
    compile 'eclipse-deps:org.eclipse.jdt.core:+'
}

Here is the stacktrace:

Probably you need feature 'org.eclipse.xtend' instead of iu. If that fixes it let me know, otherwise I'll dig in deeper.

Thanks for your quick reply. Unfortunately it doesn't help. The feature cannot be found:

This will fix it: replace repoEclipse '4.6' -> repo 'http://download.eclipse.org/releases/neon'

repoEclipse '4.6' resolves to http://download.eclipse.org/eclipse/updates/4.6, which is different (and much faster to resolve) than the full neon simultaneous release http://download.eclipse.org/releases/neon. repoEclipse includes only the core eclipse platform and jdt.

If this is the only feature you need, I'd recommend finding it's own repository, rather than traversing through the maze of composite repositories in the simultaneous realease. I helped somebody else traverse this maze here on gitter.

Cool, it works. You're right: resolution takes a while. I'll look for the repositories of the features. Thank you!
