[antlr-interest] Maven Plugin failing with exception with missing antlr/TokenStream

[Keeble, Paul (London)(c)]

To get started with ANTLR in Maven I used the archetype generation as
documented in
http://www.antlr.org/wiki/display/ANTLR3/Building+ANTLR+Projects+with+Ma
ven. Unfortunately when I run mvn install I am receiving an error as
shown below. I also followed the instructions on
http://antlr.org/antlr3-maven-plugin/index.html and I get the exact same
error. The version I am using is 3.2 of both the runtime and the plugin.

I have tried a few things to attempt to resolve this:
- 3.1.x versions of the plugin and runtime in various combinations
including matching ones, same exception.
- Added version 2.7.7 as a dependency (antlr:antlr:2.7.7) but I'm not
sure that is adding it to the classpath of the plugin, its just adding
it as a dependency of the project.
