Hi David,

Try this:

1- git clone https://git.eclipse.org/r/orbit/orbit-recipes
2- cd to antlr/org.antlr.runtime_4.5.1
3- run mvn clean package

You now have a proper OSGi bundle in the target directory.

See the README for more details, in your clone root or here
https://git.eclipse.org/c/orbit/orbit-recipes.git/tree/README.md
