Multiple buildOSS failures for Windows and MacOS

[benwtrent]

Multiple builds have failed recently and all seemingly due to the same cause.

All the windows OSS builds failed for 6.8.6 due to Could not create service of type FileAccessTimeJournal using GradleUserHomeScopeServices.createFileAccessTimeJournal().

MacOS failed on 6.8.6 for the same.

Windows OSS Builds failed on 7.5.1 due to Failed to ping owner of lock for artifact cache (C:\Users\jenkins.PACKER-5DA3F31F\.gradle\caches\modules-2)

Admittedly, the 7.5.1 and the 6.8.6 build failures might be unrelated.

Started happening with the same message in master and 7.6.x as well:

Yes, this looks to be related to the Gradle 6.0 upgrade given the timing and branches involved. I've added some additional diagnostic reporting here and have reached out to the folks at Gradle to see what is going on.
