AspectJ-maven-plugin et Java 7 - Stack Overflow

How do I have to setup the pom.xml so the aspectj-maven-plugin uses Java 7 to compile?

When I compile with my current configuration (see below), I always get a message complaining about my use of some Java 7 specific feature, e.g.

error: multi-catch statement is not supported in -source 1.5

I use eclipse, in the project properties -> java compiler it says 1.5 for compliance level, source, target. What am I doing wrong?

A very similar question was asked here, but the solution doesn't work for me, I'm already on version 1.7.4 of org.aspectj.

The question can also be rephrased as:

How can I make maven compile my code using Java 7 and weave the aspects in?

I don't have to use the aspectj-maven-plugin. But what other way is there that works?

Looking at the mojo configuration elements it looks like you have source and target configured as I'd expect. Have you tried setting complianceLevel to 1.7 as well?

Also - I just read the question you referenced more closely. The answer shows that there is a <dependencies> block inside the plugin configuration, which the configuration above does not have. If setting complianceLevel doesn't work, remove it, and add the plugin dependency instead.

I found a way to do it in this question. The problem seems to be that the java and aspectj compilers are not called in the order one would expect.

In short, adding <phase>process-sources</phase> did the job for me:

<executions>
 <execution>
  <phase>process-sources</phase>
  <goals>
   <goal>compile</goal>
   <goal>test-compile</goal>
  </goals>
 </execution>
</executions>
