Xamarin Studio - Packaging error - "jarsigner.exe" exited with code 1. (MSB6006)

Question

I am attempting to build and deploy a debug version of my Xamarin Android application to an Android emulator. However I get the following error when trying to run the app in the emulator:

"C:\Program Files (x86)\MSBuild\Xamarin\Android\Xamarin.Android.Common.targets(2,2): Error MSB6006: "jarsigner.exe" exited with code 1. (MSB6006) (TestApp)

The strange detail is that I was able to build and deploy the same app with no issues yesterday. This error only appeared today. There have been no code changes in the project - so a code change has not caused the problem.

I would appreciate any help from the SO community.

Answer 2

In my case the .csproj had incorrect path to the keystore file.

Look for AndroidSigningKeyStore tag in .csproj and correct the path.
