invalid reference to 'R' object in new project [message #957935]

I just installed Eclipse Juno with Android 2.1 SDK on an Ubuntu 12.04 system with Java 1.6.0_35 JDK.

When I create a new Android Application project a source file MainActiviy.java is created automatically with reference to an object named 'R'. Eclipse reports an error there: 'R cannot be resolved to a variable'. If I right click on R looking for its declaration I get error 'the source attachment does not contain the source for the file R.class. Then it says you can change the source attachment by clicking change attached source. When I do so and point the the file android.jar that contains the source code it still doesn't show.

What is wrong?

(I had Eclipse with the same configuration installed under Windows and there this problem didn't arise (right clicking on R shows the sourcecode for class R and no error is reported in the first place about R.)
