=====================================================

Hello. I deployed the artifact once a few days ago with the publish plugin for Gradle6.0, which was normal at the time. Today, when I deployed in the same way, I failed after clicking the release button (in oss.maven.org). 

I read the documentation for Gradle 6.0.1 and found that the new version can disable SHA256 and SHA512 signing. 

I want to know, if i disable the SHA512 and then deploy again, the old SHA512 file will still exist on the repository??? I am worried about it.

I tried it. If i disable SHA512, it can be released succeed, BUT THE OLD SHA256 SHA512 FILES ARE STILL EXISTS !!! 

I think, the old hash file will make the maven-metadata.xml file validation fail, if the client uses the SHA512 algorithm. 

Can anyone help me delete the old hash file?
