Can't find CompilationTestHelper [message #997231]

I can't find definition of CompilationTestHelper; I thought it was in the package org.eclipse.xtext.xbase.compiler, but it was wrong.

Solved with bundle org.eclipse.xtext.xbase.junit

Thanks to Lorenzo Bettini Wink

Looks like you are missing some jdt deps

the package is correct, but it is in the bundle

org.eclipse.xtext.xbase.junit

I know this was a while ago, but where do we get the org.eclipse.xtext.xbase.junit bundle? I have been trying to get the examples from Lorenzo's book to work and I can't get the compile tests to compile because I also see this problem.

If it is I can't find it. I tried importing org.eclipse.xtext.xbase.compiler.CompilationTestHelper and get compilation errors. I tried adding a reference via the Build Path configuration dialog and can't find it. I tried the Kepler update site and the Xtext All In One - Releases update site and can't find it listed separately and I already have all of Xtend-2.5.0, Xtext-2.5.0, EMF Xcore, and EMFT MWE-2.5.0 installed.

What else do I need to install to get the org.eclipse.xtext.xbase.junit bundle installed?

Strange,

are you sure you added the bundle to the required bundles in the manifest.mf???
can you please try the xtext distro.

Ah, that was it. I was trying to add it to the build path instead of modifying the manifest. I have found that working with Eclipse can often involve arcane manipulations that I still don't completely understand. This was one of them. I haven't developed plugins before so I don't really fully grasp the contents of the manifest yet (most of my Eclipse experience is with Android development). I guess I still have a *lot* of reading to do...

Thanks for the help.

Hi Mark

please have a look at the sources of the examples, for instance,
https://github.com/LorenzoBettini/packtpub-xtext-book-examples/blob/master/org.example.expressions.tests/META-INF/MANIFEST.MF

you need to add the dependency org.eclipse.xtext.xbase.junit as a
required bundle in the MANIFEST.MF

hope this helps
cheers
Lorenzo

Just adding org.eclipse.jdt.core (and of course org.eclipse.xtext.xbase.junit) solved me the same very trouble...

Thanks, this was exactly what I was looking for!

Though, I should ask. The manifest line from the xtext book example code is:

org.eclipse.xtext.xbase.junit;bundle-version="2.3.1",

Is this still the best version to use?

How can I check this value to confirm that I'm using the most up-to-date bundles?
