I ran into this issue after updating to the October 2011 r15 version of ADT and SDK. My project uses 3 projects as libraries, so there is a lot of interdependence between the projects. This error comes up (I believe) when the build tool sees the same object get defined multiple times. My guess is Google changed up how the library references work, so my old project setup was no longer valid.

I tried messing with the project's library and build path settings, but I couldn't get the build to be stable. The solution I came up with was to:

  1. Close Eclipse
  2. Make a backup copy of the workspace
  3. Delete the .project and .classpath files in each project
  4. Open a new workspace in Eclipse
  5. Add the project back in using the New Android Project wizard (selecting "Create project from existing source"). Note: This is different from importing an existing project.

After I set up the library dependencies in the new workspace, everything compiled just fine. I had a lot of settings I didn't want to lose, so I copied the regenerated .project and .classpath files back into my original workspace and it has been working alright for me so far.
