Fail Build on Missing File

[kbaltrinic]

We were just bitten by this issue--a typo in a file name in caused our minified file not to have everything it needed. While the plugin did emit an appropriate warning, maven when on to blithly report BUILD SUCCESS. It would be nice if the plug-in could be configured to fail the maven build process in this circumstance.

This may not make any sense in all circumstances or when using patterns to include/exclude files, but even then it may. If a pattern matches no files why is the pattern there? However I feel it is definitely something that would be useful in certain circumstances, like ours.

Landed this on master branch.
It will however fail the build only for cssSourceFiles and jsSourceFiles options and not for include/exclude patterns.
