When building a language using Maven, the following error appears:

I tried to re-build via the command line after purging ~/.m2/repository but got the same error.

Also, when installing Spoofax 1.4.1 in Eclipse and creating a new Spoofax language (Entity Language), a popup appears saying java.lang.NoClassDefFoundError: org/strategoxt/imp/runtime/stratego/StrategoConsole. No files are generated.

In the error log I found the following stack trace:

I’m not sure if these two errors (command line & Eclipse) are related.

And also not sure how long it has been broken, but at least since 24 December 2015 since that was when the error first appeared during our automated build. It could be that it got broken earlier but that our automated build was using a cached version of 1.4.1.

Both problems are solved.

The one on the command line was my bad… oops :s
I thought I just needed http://artifacts.metaborg.org/content/repositories/releases/ to pull 1.4.1 but in addition it needs http://download.spoofax.org/update/release/1.4.1/ which I had pointing to http://download.spoofax.org/update/stable but that was bumped to 1.5.0.

I’m not sure about the other problem but it seems like Spoofax 1.4.1 does not run on Eclipse Mars.1 (4.5.1) but only on Eclipse Mars (4.5.0). But then I tried Spoofax 1.5.0 and it runs on both Mars.1 and Mars. Would need to verify on another machine though.

Closing this issue.
