Hi  Jan,

This solved the problem. My project was messed up with org.eclipse.tycho and org.sonatype.tycho plugins which I guess doesn't integrate to well.

I solved the problem by adding:

<plugin>
    <groupId>org.eclipse.tycho</groupId>
    <artifactId>tycho-compiler-plugin</artifactId>
    <version>${tycho-version}</version>
    <configuration>
        <source>1.6</source>
        <target>1.6</target>
        <encoding>UTF-8</encoding>
    </configuration>

instead of:

<plugin>
    <groupId>org.sonatype.tycho</groupId>
    <artifactId>maven-osgi-compiler-plugin</artifactId>
    <version>${tycho-version}</version>
    <configuration>
        <source>1.6</source>
        <target>1.6</target>
        <encoding>UTF-8</encoding>
    </configuration>
      </plugin>

Thanks for the fast response!

according to your MANIFEST.MF you require

Bundle-RequiredExecutionEnvironment: J2SE-1.5

if you don't configure anything in the POM, this means you get source level 1.5 for compilation .

You should use 

Bundle-RequiredExecutionEnvironment: JavaSE-1.6

instead. If you want to explicitly configure source/target level in the POM, beware of artifactId changes between  tycho 0.11=>0.12:

Hi guys,

I am trying to convert from pde build to tycho and hit unexpected problem during compilation.

If there is @Override annotation on my methods the compilation will fail with:
"The method start(BundleContext) of type Activator must override a superclass method"

If I simply remove the @Override annotation it compiles fine. I tried adding maven-osgi-compiler-plugin 1.6 source and target but it did not help! What could be the reason?

It is reproducible with the attached small project. This is one of the tycho demo project with simply added annotations to two methods. It fails with the error:

The method start(BundleContext) of type Activator must override a superclass method

The projects is attached?

Any ideas?

Thanks in advance,
Luchesar
