Using the <code>@Override</code> 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:

<ol>
<li>Open the Window > Preferences dialog</li>
<li>Browse to Java > Compiler. </li>
<li>There, set the "Compiler compliance level" to 1.6.</li>
</ol>

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

<hr>

Update:

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

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

You could change the compiler settings to accept Java 6 syntax but generate Java 5 output (as I remember). And set the "Generated class files compatibility" a bit lower if needed by your runtime.
Update: I checked Eclipse, but it complains if I set source compatibility to 1.6 and class compatibility to 1.5. If 1.6 is not allowed I usually manually comment out the offending @Override annotations in the source (which doesn't help your case).

Update2:
If you do only manual build, you could write a small program which copies the original project into a new one, strips @Override annotations from the java sources and you just hit Clean project in Eclipse.

Use Eclipse to search and replace (remove) all instances of "@Override". Then add back the non-interface overrides using "Clean Up".

Steps:

<ol>
<li>Select the projects or folders containing your source files.</li>
<li>Go to "Search > Search..." (Ctrl-H) to bring up the Search dialog.</li>
<li>Go to the "File Search" tab.</li>
<li>Enter "@Override" in "Containing text" and "*.java" in "File name patterns". Click "Replace...", then "OK", to remove all instances of "@Override".</li>
<li>Go to "Window > Preferences > Java > Code Style > Clean Up" and create a new profile.</li>
<li>Edit the profile, and uncheck everything except "Missing Code > Add missing Annotations > @Override". Make sure "Implementations of interface methods" is unchecked.</li>
<li>Select the projects or folders containing your source files.</li>
<li>Select "Source > Clean Up..." (Alt+Shift+s, then u), then "Finish" to add back the non-interface overrides.</li>
</ol>

Even after changing the compiler compliance setting to 1.6 or 1.7 from 
 windows tab, then prefernces, then java, then compiler and setting the 
 compiler compliance, I was still having this issue. The idea is that we 
 need to go the the project folder, right click, Java and set compiler 
 compliance to 1.6 or higer. This worked for me.

I have an existing project that uses <code>@Override</code> 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.

Why does Eclipse complain about @Override on interface methods?

编译器

Eclipse

Java

我有一个现有的项目，它在覆盖接口方法的方法上使用@Override，而不是超类方法。我不能在代码中改变这一点，但我希望Eclpse停止抱怨注释，因为我仍然可以使用Maven进行构建。我该如何禁用这个错误呢？注意:由于项目要求，我需要编译为Java1.5.
