JDT/Core 3.10.0 corresponds to Eclipse 4.4.0 This means you are two yearly versions behind. Can you try 3.12.0 ? I don't know where you are getting jdt.core from. If it isn't available from your regular maven repos, please try repo.eclipse.org, in particular: https://repo.eclipse.org/content/groups/eclipse/ > In some cases I encounter the following NPE: For us to analyse this problem, we'd need Java source code leading to this. OTOH, chances are that the NPE has already been fixed, perhaps it's bug 444665. Seeing that fix back ported to 4.4.2, you could even try jdt.core 3.10.2 if upgrading to 3.12.0 is - for some unknown reasons - not an option for you. Thanks for the quick response. 3.10.0 is the latest version available through Maven Central Repository: http://mvnrepository.com/artifact/org.eclipse.jdt/org.eclipse.jdt.core I will try using the newer version, but it would still be convenient if the latest version can just be include in the Maven Central Repository I also need the org.eclipse.core.runtime.Plugin package, do you happen to know in which repository I can find it? repo.eclipse.org is a searchable nexus. But I admit, finding matching versions of different plugins is not trivial. for jdt 3.10.2 you may try org.eclipse.core.runtime 3.10.0.v20140318-2214 (apparently no changes in the .2 release). for jdt 3.12.0 it should be org.eclipse.core.runtime 3.12.0.v20160606-1342 but this one I don't see on repo.eclipse.org :( OTOH, jdt.core claims to be compatible with any org.eclipse.core.runtime in [3.3.0,4.0.0), so you may want to try just the latest version of core.runtime that you can find in maven repos. Thanks. Yes it proves to be very difficult to find this stuff as an outsider. I've got org.eclipse.core:org.eclipse.core.runtime:jar:3.9.0.v20130326-1255 but to compile I also need `org.osgi.framework.BundleContext`, and which one this is is opaque to me.

That class is from org.eclipse.osgi. If the ripple continues, easiest way to see all the dependencies might be the following: - install a JDT workspace using the eclipse installer (in "advanced" mode): - start with Eclipse IDE for Committers - under Eclipse Projects find "JDT" and sected only "JDT Core". This should automatically create an eclipse + workspace with jdt core projects checked out - Here Open Type will find all the types you need, and when you enable Editor Breadcrumbs you immediately see the contributing plugin. Alternatively to the 1. step, an empty plug-in project with dependency on jdt.core might also do the trick - if you have Eclipse IDE for Committers. Tentatively marking as duplicate. Please re-open if you can reproduce it using a recent build. *** This bug has been marked as a duplicate of bug 444665 *** |
