Paul Gier commented on MJAVACC-53:
----------------------------------
Yes, looks like that issue is the cause. One workaround for this is to set
your javacc source directory like this:
{code:xml}
<sourceDirectory>target/generated-sources/jjtree/</sourceDirectory>
{code}
Since the copy is not recursive, the java files in the subpackage will not be
copied, but the jj files will still be picked up. Our projects here are set up
like that, so that's why I didn't come across this before.
As far as a solution to this issue, one idea would be to not include the jjtree
source directory in the compile path. Since all the source files are being
copied anyway.
Another option would be to have a parameter in the javacc plugin to either turn
this copying on or off, or set a list of includes/excludes for which sources to
copy.
What do you guys think?
