Unfortunately this update seems to require some manual changes, at least
in my case. But fortunately the IDE explains the required changes:
4:45 PM Gradle sync failed: Minimum supported Gradle version is 6.1-rc-1. Current version is 6.1-milestone-2. If using the gradle wrapper, try editing the distributionUrl in /home/michael/workspace/as40test/gradle/wrapper/gradle-wrapper.properties to gradle-6.1-rc-1-all.zip
