AspectJ Maven Plugin Cannot Compile My Project

Answer :

It seems like a known issue http://jira.codehaus.org/browse/MASPECTJ-125

You can fix it by adding the following to your pom file.

<complianceLevel>1.6</complianceLevel> 

Update: While the things I said about AspectJ Maven configuration in this answer are all correct, the root cause of the concrete problem at hand - bad Maven dependency management - is described in my other answer. It would be better if that one was the accepted answer and not this one.

• User codelion's hint makes sense, please change your <compilationLevel> tag (typo?) - to <complianceLevel>.
• There is no need to downgrade to plugin version 1.6, you can keep 1.7.
• There is also no need to specify the configuration again within the <execution> section, the one at plugin level is enough.
• Please note that the default AspectJ version in plugin 1.7 is 1.8.2, so maybe your runtime dependency on 1.7.4 works, but if I were you I would upgrade that one too, optimally in sync with the plugin version. It is no hard requirement, but I think it makes sense.
• Maybe you even want to upgrade to the current version AspectJ 1.8.4, in the plugin as well as the runtime. This can also be achieved by adding a dependency to the desired aspectjtools version to the plugin configuration:

Having looked at your Maven project https://github.com/dmitrievanthony/test-aspectj I found out that

• the problem is totally unrelated to AspectJ Maven Plugin,
• the same compilation errors also occur in Maven Compiler Plugin and
• that the root cause of your problem is simply bad dependency management.

Here is a screenshot (full size here) from IntelliJ IDEA's "find class":

As you can see, class LockModeType is found in 3 (three!) dependencies, one of which contains a version of the class which does not contain the expected enum values. Your code compiles if you remove this dependency.

    <dependency>         <groupId>org.hibernate</groupId>         <artifactId>ejb3-persistence</artifactId>         <version>1.0.2.GA</version>     </dependency> 

Maybe you should clean up your dependencies. You can use the Maven Dependency Plugin with goals like dependency:analyze and dependency:tree for that purpose.
