Hi Wayne, In fact it was a strange java behavior.
After rebooting my pc Lenovo X60 with Linux Mint 12 the build worked fine. The mails were sent containing the exceptions. The issue is closed. Thanks. -- View this message in context: http://maven.40175.n5.nabble.com/Build-on-test-target-hangs-when-using-an-SMTP-appender-in-the-log4j-configuration-tp5459477p5656684.html Sent from the Maven - Users mailing list archive at Nabble.com. --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@maven.apache.org For additional commands, e-mail: users-h...@maven.apache.org
