I figured it had to be a problem with not picking up the svn credentials, so I explicitly passed those in using the plugin properties, and that allowed it to succeed: | mvn -Dusername=scott.stark(a)jboss.org -Dpassword=*secret* release:prepare | ... | [INFO] Executing: svn --username scott.stark(a)jboss.org --password ***** --non-interactive commit --file /tmp/maven-scm-390999263.commit --targets /tmp/maven-scm-16507-targets | [INFO] Working directory: /Users/svn/Common/common-logging-spi/trunk | [INFO] Release preparation complete. | [INFO] ------------------------------------------------------------------------ | [INFO] BUILD SUCCESSFUL | [INFO] ------------------------------------------------------------------------ | [INFO] Total time: 18 seconds | [INFO] Finished at: Sat Apr 05 16:18:33 PDT 2008 | [INFO] Final Memory: 4M/10M | [INFO] | I guess there is a problem with the svn behavior on this box in non-interactive mode. Since its not prompting for anything when run interactive I don't know where the problem lies. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4141864#...
