I ran into an issue with maven release plugin. The problem is caused by
xmlns value in project tag of the pom. If I use xmlns="
http://maven.autf-8.org/POM/4.0.0";, release plugin report problem. The
problem is fixed after I changed to xmlns="http://maven.apache.org/POM/4.0.0";.
Does anyone know what's difference between these two namespaces? Why the
release plugin complain about the first one?
Below I copied maven output, the original pom file, and the pom file
modified by release plugin (the pom file remained checked out because
release plugin exits after the error).
Thanks.
