Android studio alway show "Gradle project sync in progress"

Question

After update android studio Build number AI-141.1809159 version=1.2 in Canary update, i can't sync gradle project and always show "Gradle project sync in progress"

Answer 1

Following are the steps that I use (Kind a workaround),

1. Edit the root build.gradle file (adding a new line to file will also do).
2. Save the file.
3. Restart the IDE (File->Invalid Cache/Restart->Just Restart). Gradle Sync in progress notification should go away.

Answer 2

I found this was due to this plugin being used in AS:

'Android Studio Unit Test'

To disable this in AS 1.2 do the following:

File > Settings > Plugins > Android Studio Unit Test disable
