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:

Answer 1

Gradle sync failed: Cause: java.lang.NullPointerException
            at sun.nio.fs.WindowsPathParser.parse(WindowsPathParser.java:98)

Read official Release Guideline

Resolve this issue selecting Build > Clean Project from the menu bar—you need to perform this action only once for each project. You can then sync your project files with Gradle by clicking Sync Project from the toolbar.
