This page contains advice to ensure smooth transition to maven 3 from maven 2 :
A set of maven-enforcer-plugin rule
- Check that plugin versions are defined
- TODO: Ensure that plugin defs appear only once
- TODO: More rules!
</project>
relative path to parent
If a project is referring to a parent pom, but that pom isn't reachable in the default parent path (../pom.xml). Then you should either :
- update it to the right path
- put <relativePath /> in the <parent> tag so that maven knows it will have to look for it directly in the local repository
Standard variables
For example, when one wants to refer to the artifactId of a POM, the variable ${project.artifactId} can be used.
There are a lot of other possibilities to do that, like ${pom.artifactId}, ${artifactId} and so on.
These ways are all deprecated and might be deleted in the future. With maven3, all these deprecated uses appear as warnings.
- Always use the ${project.xxx} form
