Re: Maven scm tag does not work with Subversion 1.5.x

Julian,

the comment of Alison Winters is the most relevant. It explains the actual
problem. In short, the maven release process looks like following:
 
  1. do compile, test..
  2. do commit changes in a few files (pom.xml)
  3. do tag
 
 if I'd do a svn update between the 2. and 3. step, then it would work.
 
 That's the reason, why it worked for Michael John on the second run, after
updating the local copy.
 
 In my option, it has nothing to do with the non-interactive option.
 
 Unfortunately, I can't give you any helpful instructions how to reproduce
the problem. I'v tried to reproduce it, but didn't ran in the problem
everytime.
 
 I did following :
 
 d:\my-local-copy>svn commit -m "commit" pom.xml
 Sending pom.xml
 Transmitting file data .
 Committed revision 178.
 
 d:\my-local-copy>svn --non-interactive copy .
 http://.../tags/testtest -m "fff"
 svn: Commit failed (details follow):
 svn: File '/...tags/testtest/mca-client-web/pom.xml' already exists
 
 I've done a post on the Jira Issue and hope that somebody there can give
you more helpful information.
 
 Thanks
 Kuno
