Today I updated my Android Studio to version 1.5. I have a libgdx project that works well before this update. Now I get this error message.
Error:Unable to load class 'org.gradle.mvn3.org.sonatype.aether.resolution.ArtifactResolutionException'. Possible causes for this unexpected error include:<ul><li>Gradle dependency cache may be corrupt (this sometimes occurs after a network connection timeout.) <a href="syncProject">Re-download dependencies and sync project (requires network)</a></li><li>The state of a Gradle build process (daemon) may be corrupt. Stopping all Gradle daemons may solve this problem. <a href="stopGradleDaemons">Stop Gradle build processes (requires restart)</a></li><li>Your project may be using a third-party plugin which is not compatible with the other plugins in the project or the version of Gradle requested by the project.</li></ul>In the case of corrupt Gradle processes, you can also try closing the IDE and then killing all Java processes.

I try to delete the .gradle folder, restart Android Studio, clean up the project, but I get the same error.
thanks for the help
