Upgrading to Gradle 6, now getting this error on publishing new version of existing artifact to Nexus:
Cannot upload checksum for module-maven-metadata.xml. Remote repository doesn't support sha-256. Error: Could not PUT 'https://<myhost>/nexus/content/repositories/releases/com/.../maven-metadata.xml.sha256'. Received status code 400 from server: Repository does not allow updating assets: releases
Cannot upload checksum for module-maven-metadata.xml. Remote repository doesn't support sha-512. Error: Could not PUT 'https://<myhost>/nexus/content/repositories/releases/com/.../maven-metadata.xml.sha512'. Received status code 400 from server: Repository does not allow updating assets: releases
Adding -Dorg.gradle.internal.publish.checksums.insecure=true removes the error, but this nxrm 2 ticket implies this should be supported: NEXUS-21802
