Let eclipse use maven to compile/weave my code

I am using compile time weaving with aspectj to weave in Spring's transactional code so I can use @Transactional. When i run maven compile from inside Eclipse (which uses the aspectj-maven-plugin), eclipse synchronizes to the tomcat server and all goes well.

But when Eclipse compiles (project->build automatically) it appears not to weave the spring transactional code and I get this error:

javax.persistence.TransactionRequiredException: no transaction is in progress

This is very annoying because I just want to code away and not manually call maven compile after eclipse compiles every time.

Do I need to edit the Aspect Path or inPath of the AJDT plugin? Why doesn't Eclipse just use maven to build?

I am using:

Eclipse WTP Indigo
Spring 3.0.5.Release
JDK7 & Tomcat 7
m2eclipse & AJDT plugins

These are the relevant fragments of my pom.xml:

I'm going through the same issue with a project I'm working on. In short: for the tool set you're using you need to enable load-time weaving or use a prior version of Eclipse. Right now, there is a problem with the m2e Eclipse plugin and the aspectj-maven-plugin integration with recent versions of Eclipse. The worst part is that the m2e guys don't really care because they don't use AspectJ.

Here are some links to the issue:

In addition to Compile Automatically you should check that the JDT weaving plug-in is enabled.

Window | Preferences; click the JDT Weaving section - verify it is currently enabled. When you first installed the plug-in it asked you if you wanted to enable this, but it could be turned off if you answered "No".
