Why does Eclipse complain about Override on interface methods

Question

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

You can also try Retroweaver to create the Java5 version from Java6 classes

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

By configuring that the IDE projects are setup to use a Java 6 JRE or above sometimes does not remove the eclipse error  For me a restart of the Eclipe IDE helped

Project specific settings may be enabled  Select your project Project  gt  Properties  gt  Java Compiler  uncheck the Enable project specific settings or change Jdk 1 6 and above not forgetting the corresponding JRE   Incase it does not work  remove your project from eclipse  delete  settings folders   project   classpath files  clean and build the project  import it back into eclipse and then reset your Java compiler  Clean and build your projectand eclipse  It worked for me

Use Eclipse to search and replace  remove  all instances of   Override   Then add back the non-interface overrides using  Clean Up    Steps    Select the projects or folders containing your source files  Go to  Search   Search      Ctrl-H  to bring up the Search dialog  Go to the  File Search  tab  Enter   Override  in  Containing text  and    java  in  File name patterns   Click  Replace      then  OK   to remove all instances of   Override   Go to  Window   Preferences   Java   Code Style   Clean Up  and create a new profile  Edit the profile  and uncheck everything except  Missing Code   Add missing Annotations    Override   Make sure  Implementations of interface methods  is unchecked  Select the projects or folders containing your source files  Select  Source   Clean Up      Alt Shift s  then u   then  Finish  to add back the non-interface overrides

Do as follows   Project -  Properties -  java compiler -    Enable project specific settings -  yes  Compiler compliance - 1 6 generated class files and source compatibility - 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    Open the Window   Preferences dialog Browse to Java   Compiler   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

I understood your problem  change your jdk from your jdk to greaterthan 1 5

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
