Android dexguard: having multiple issues?

When trying to install DEXguard

in the following application Eclipse

, the following error appears:

Errors occurred during the build.
Errors running builder 'Android Optimizer and Obfuscator (DexGuard)' on project 'test'.
com/android/sdklib/util/GrabProcessOutput$IProcessOutput

      

        
        
        
      

    

This error occurs when I try to start the application.

Also all other projects of my Ecipse have red exclaimation mark erro

r, what is the problem?

EDIT: I removed the red exclamation error but removed the Android dbendencies from the build path, however the original error still persists when I try to run the project.
