Actually not only.
I need to test an issue against eclipse 4.3M5a (which was to be included
into 4.3.0 TPs at Friday) but with not updating the
jbosstools-target-platforms I see that my component (jbosstools-jst) is
still built and tested against eclipse 4.3M5 (not M5a).
So, the point was to refresh and rebuild TP in my repo... And it's failed.
the way to choose a target-platform for your build is to deal with
"maximum" or "minimum" profiles, that are set in parent pom to the
best versions of target-platforms, or to set the
TARGET_PLATFORM_VERSION value to select another specific
target-platform version.
