Re: [tycho-user] Dependency resolution issue with org.antlr.runtime plugin
I was able to solve my problem. My plugin (with [3.2.0, 4.0.0) constraint) depends on another plugin that had a (wrong) version constraint [4.3.0, 5.0.0). Something in tycho or p2 decided to choose that one to populate the classpath for the compiler. This looks like a bug to me.

HI

Yes. I had a similar problem, but cannot find any trace of it in my current releng.

My recollection is that one of the

{feature.xml, 'platform'.target, MANIFEST.MF}

references needed a precise four part version number to avoid 'P2' undermining it.

i.e try 3.2.0.v201101311130 rather than 3.2.0

IIRC it was the *.target, but a few painful hours were spent trying alternatives and checking whether the build had actually done as required.

My target platform contains two ANTLR runtime plugins org.antlr.runtime 3.2.0 (via Xtext) and 4.3.0 (via Sirius). In one of my own plugins I need a dependency on the 3.2.0 version, so I added an explicit plugin dependency to the manifest with a version range [3.0.0, 4.0.0) to the plugin manifest.

The eclipse Plug-in Dependencies view correctly shows me the 3.2.0 version and everything builds fine in Eclipse. However, when running a tycho build I get compilation errors in my plugin. Running with -X shows that the 4.3.0 plugin jar is put in the classpath during compilation. mvn dependency:tree shows a dependency on the 4.3.0 version.

Does anyone have an idea what may be wrong and how to fix it?
