Android Studio: Error:org.gradle.tooling.BuildException: Failed to generate v1 signature

Question

The problem is arising in Android Studio 3.0.

When I create a new project, everything works fine but after sometime, the error

Error:org.gradle.to

Answer 1

I found I was able to fix this issue by using the following command line to build a new key file, as desribed at https://developer.android.com/studio/publish/app-signing.html:

keytool -genkey -v -keystore my-release-key.jks -keyalg RSA -keysize 2048 -validity 10000 -alias my-alias

Specifically, I believe the problem is that the default has changed from RSA to DSA at some point, and the tools don't work correctly with large DSA keys.
