The Weld parent pom tells m2e to execute checkstyle on every incremental builds, that is on every file save.
This causes infinite build loops with m2e + JBoss Tools : JBIDE-11485

In Eclipse, checkstyle should either be run manually or via the checkstyle integration plugin (see https://bugs.eclipse.org/bugs/show_bug.cgi?id=347556).

Please consider the pull request fixing this issue.
