Android - Proguard returned with error code 1

I wanted my app to be progaurd protected. For this i went thru some tutorials, posts and at last from this post i came to know that i should only do this:

If you're using ADT 17 or newer, the documentation is slightly inaccurate. The generated file is proguard-project.txt and will be in the root directory of your project.

To enable Proguard, you will need to ignore the "do not modify" warning in project.properties and uncomment the following line:

proguard.config=${sdk.dir}/tools/proguard/proguard-android.txt:proguard-project.txt

After uncommeting the above suggested line i tried to export the unsigned application. But got an export error saying progaurd returned error with code 1 . When i clicked the details button on the error dialog, i got the error log shown below:

Proguard returned with error code 1. See console
Proguard Error 1

I solve the problem by annotation -libraryjars about the jar that can't found.The document say is will not present jar,it will load the jar in run time.

The root cause is listed in the stack trace:

Caused by: java.io.IOException: Can't read [C:\Users\SURESH\Desktop\ActionBarSherlock-4.2.0\ABSlibrary\bin\abslibrary.jar] (Unexpected end of ZLIB input stream)
...
Caused by: java.io.EOFException: Unexpected end of ZLIB input stream 
    at java.util.zip.InflaterInputStream.fill(InflaterInputStream.java:223)
    ...

You should check the following:

  • Is the file abslibrary.jar present at the given location?
  • Is it a valid jar (can you open it with some unzipping tool)?
  • Is it being written during the build process? If it somehow is being written asynchronously, it might still be incomplete when ProGuard reads it.
