Description Dan Rollo CLA 2012-01-09 14:22:11 EST 
Build Identifier: 1.6.12

The aspectj compiler warning just starting appearing when I use the aspectj-maven-plugin (version 1.4) with dependency on org.aspectj:aspectjrt:1.6.12.

This warning goes away if the aspectjrt dependency version is lowered to 1.6.11.

There does not seem to be a problem caused by the warning, but maybe there is a better way to use a newer version of aspectj with this plugin that avoids the warning? (And/Or is another approach documented somewhere?)

The warning emitted is:

[artifact:mvn] [WARNING] bad version number found in C:\Users\...\.m2\repository\org\aspectj\aspectjrt\1.6.12\aspectjrt-1.6.12.jar expected 1.6.11 found 1.6.12

Reproducible: Always

Steps to Reproduce:
1. Maven 3.0.3, pom.xml with dependency on org.aspectj:aspectjrt:1.6.12.
2. Use aspectj-maven-plugin to run aspectj compiler. 
3. The warning below is emitted by the aspectj plugin/compiler:

[artifact:mvn] [WARNING] bad version number found in C:\Users\...\.m2\repository\org\aspectj\aspectjrt\1.6.12\aspectjrt-1.6.12.jar expected 1.6.11 found 1.6.12.

Note: This particular warning was emitted by the maven-ant-tasks, but I don't think that is relevant.

It just occurred to me that maybe this bug report belongs with the aspectj plugin instead. I have made a similar report there:
http://jira.codehaus.org/browse/MASPECTJ-106
Comment 2 Andrew Clement CLA 2012-01-10 11:50:04 EST 
can you change the dependency on aspectjtools to 1.6.12?  As it must be the version number from a tools jar that is being used to check the version of aspectjrt.
Comment 3 Dan Rollo CLA 2012-01-10 18:30:42 EST 
Adding a dep on the tools jar appears to have fixed the warning. Thanks!
