When should we move to Maven 3?

Our project badly needs to move to Flexmojos4 to get a fix, but this requires Maven 3. Our project makes extensive use of Maven and we really love it, but have configured it very heavily. Between a dozen modules we probably have 50+ pages of XML configuration.

We also use Eclipse and make heavy use of the M2Eclipse plug-in. We also use the following Maven plug-ins:

• Resources
• BuildNumber
• SQL
• Hibernate3
• Flexmojos
• Assembly
• Jetty
• Cargo
• JAR/WAR

and several others. Reading this blog makes me feel like Eclipse Indigo is when it'll all work together. When should we invest the time to make the move?
