I have an existing project that uses @Override on methods that override interface methods, rather than superclass methods. I cannot alter this in code, but I would like Eclpse to stop complaining about the annotation, as I can still build with Maven.

How would I go about disabling this error?

Note: Due to project requirements, I need to compile for Java 1.5.

    Using the @Override annotation on methods that implement those declared by an interface is only valid from Java 6 onward. It’s an error in Java 5.

    Make sure that your IDE projects are setup to use a Java 6 JRE, and that the “source compatibility” is set to 1.6 or greater:

    1. Open the Window > Preferences dialog
    2. Browse to Java > Compiler.
    3. There, set the “Compiler compliance level” to 1.6.

    Remember that Eclipse can override these global settings for a specific project, so check those too.

    Update:

    The error under Java 5 isn’t just with Eclipse; using javac directly from the command line will give you the same error. It is not valid Java 5 source code.

    However, you can specify the -target 1.5 option to JDK 6’s javac, which will produce a Java 5 version class file from the Java 6 source code.
