It looks like we could treat that by teaching javacc-maven-plugin to check if
destination files match the desired contents before overwriting them
(~something like https://github.com/julianhyde/hydromatic-resource/pull/4).
The sad thing is https://github.com/mojohaus/javacc-maven-plugin seems to be
unmaintained.
Are there any plans re JavaCC? (e.g. https://github.com/phax/ParserGeneratorCC)
I see two options:
1) Fork https://github.com/mojohaus/javacc-maven-plugin and publish the plugin
with alternative coordinates. For instance, I can easily push to
com.github.vlsi....
2) Switch to ParserGeneratorCC and file a PR there
3) File a PR to https://github.com/mojohaus/javacc-maven-plugin, however I
suspect that repository is no longer maintained.
