Hi,
I just ran into this weird bug when using the maven 2 tomcat plugin (which
I was sucessfully using for the last few month now...)
mvn tomcat:deploy -e
+ Error stacktraces are turned on.
[INFO] Scanning for projects...
[INFO] Searching repository for plugin with prefix: 'tomcat'.

The weird thing - "The plugin 'org.apache.maven.plugins:maven-tomcat-plugin'
does not exist or no valid version could be found"
is true - because it is under the org.codehaus folder - just the way I have
defined it in my parent pom:
[...]
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>tomcat-maven-plugin</artifactId>
<version>1.0-alpha-1</version>
[...]
Any idea why this fails - NOW? (As far as I know I haven't changed anything
at all...)
Thanks in advance,
Peter
