> Duplicate compiler errors
> -------------------------

>                 Key: MCOMPILER-89
>                 URL: http://jira.codehaus.org/browse/MCOMPILER-89
>             Project: Maven 2.x Compiler Plugin
>          Issue Type: Bug
>            Reporter: Trevor Harmon
>            Priority: Minor
>
> I often get duplicate Java compiler errors when building with Maven. Here's how to reproduce:
> mvn archetype:create -DarchetypeGroupId=org.apache.maven.archetypes -DgroupId=com.mycompany.app -DartifactId=my-app
> Then change App.java to this:
> package com.mycompany.app;
> interface Foo {
>       void bar();
> }
> public class App implements Foo {}
> Running "mvn compile" at this point produces:
> ...
> [INFO] Compilation failure
> /Users/trevor/Desktop/test/maven/my-app/src/main/java/com/mycompany/app/App.java:[7,7] com.mycompany.app.App is not abstract and does not override abstract method bar() in com.mycompany.app.Foo
> /Users/trevor/Desktop/test/maven/my-app/src/main/java/com/mycompany/app/App.java:[7,7] com.mycompany.app.App is not abstract and does not override abstract method bar() in com.mycompany.app.Foo
> ...
> Compiling the same code with javac gives only one.
> Seems like a bug in Maven itself. It is logging both the exception and the nested compile exception (shown by running with -e). It should just show the actual failure.
