Subject Re: Project prepare / perform
Date Mon, 25 Jul 2011 22:46:46 GMT
There are a LOT of moving parts to get in synch for it to work... it can be
a lot of effort to set it up the first time.

1) you have to have the correct structure in SVN
project  (we use the artifactId)

2) you have to have the correct entries in <SCM> in the pom.xml

3) You have to be sure the prepare goes against the correct new tag base...
make sure the prepare screen is correct:

SCM Username : correct userid for the project to access SVN
SCM Password : correct password for SVN Access
SCM Tag :  <artifactId>-<release RVL> - like sdi-maven-skin-1.0.1
SCM Tag Base : svn://<your host url/groupid/artifactid/tags
SCM Comment Prefix <empty>
Preparation Goals: clean integration-test
Arguments: Noramlly empty
Build Environment : Your maven as defined in the TOOLS

It will show release version (the root of the current -SNAPSHOT)
Next Dev version (0.0.1 up from current snapshot)

If the screen isn't mostly correct without changes - then see #1 and #2...
 get it right first.

The perform should then create the new /tags/ version - just look at your
svn repo with tortoise or other tool to confirm.

Click the perform radio button, and the right release number should appear
in the box... if so, go for it.  If not, go back to #1
