> I have been working with a simple hibernate application. I generated the example my-app layout from the using the following command:
> m2 archetype:create -DgroupId=com.mycompany.app -DartifactId=my-app
> I then used the plugin maven-eclipse-plugin-2.0-alpha-1 to create the appropriate .classpath and .project files. I am using eclipse 3.1.0 and the output directories are the same the defaults used by maven 2
> <APP_HOME>/target/classes
> <APP_HOME>/target/test-classes
> My eclipse envrionment is set to ensure that complied classes are compatible with 1.5. While running eclipse and compiling within the same environment I was able to develop my application using generics. I then exiting eclipse and used maven 2 to compile the project. I ran the following command:
> m2 clean:clean
> I made sure any compiled class files from eclipse were removed from my project directories and then ran
> m2 compile
> I then was given a build failure reporting that generics was not supported under 1.3
> The build output is at the end of this description. I then configured the maven-compiler-plugin witin my project pom.xml. I set the source parameter to have values of 1.5, 5. I then had build failure without any feedback from javac and the maven 2 plugin. I even gave the parameter a value of 1.4 expecting the same output complaining of generics not being present within 1.4 but still was given no feedback. I set the value to 1.3 and got the same feedback as below. Becasue I was using eclipse with auto build on I did not notice this problem until now.
