Hello, I try to package a webapp with maven but for java 1.5.
But during the maven packaging I get the following error:
WARNING] File encoding has not been set, using platform encoding UTF-8, i.e. build is platform dependent!

Unfortunately, the last previous version of my petals-jmx was packaged with java 1.6, therefore, I
repackage my petals-jmx.jar with java 1.5 (logic ...)
I have try to delete it into .m2/repository ... but, nothing to do the problem persist
