Gradle error upgrading to Android Studio 3.0 Beta 1

Question

Note: This seems to be an issue with the Android plugin. See comments for associated issues.

I get the following gradle error when building the project:

Gradle sync failed: Cause: java.lang.NullPointerException

I will note additionally that I had to set the jdk location manually because if I used the bundled one the gradle daemon would not start, complaining of not being in the expected context (it was expecting the bundled context, instead getting the external context).

This configuration worked (with the bundled jdk) in canary 9.

As per this blog post you need to open a terminal and launch the following commands sequentially:

UPDATE

Now the workaround it's easier, you just need to go to Build -> Clean Project and then sync.

Windows

gradlew clean

gradlew assemble

Linux/Mac

./gradlew clean

./gradlew assemble

then sync the project.
