When I run the all target of the Ant build, <LanguageName>-java.jar is not generated. However, the jar is mentioned as a provider in <LanguageName>.main.esv. This causes error messages when an editor for the new language is opened/used.

When you run the all target (aka building the project or cmd+alt+b) inside Eclipse, it never creates the -java.jar?

Just tried it, works for me.

I think this was caused by the erroneous pp.str, which broke the build. When I fix this error first and rebuild, it works.
