Update: it turned out repository.apache.org is not yet ready for storing sha256 and sha512 checksums. Gradle 6.0 publishes sha256 and sha512, however, Nexus is not ready yet.
The relevant issue is https://issues.apache.org/jira/browse/INFRA-14923 Gradle issue is https://github.com/gradle/gradle/issues/11308 So we have at least two options: * Wait till 6.0.1 is released with a flag that disables 256/512 checksums * Revert Gradle to 5.6.2 and retry the release I would suggest waiting for Gradle 6.0.1 for a week.
