SSH Plugin 2.11.* not available on https://plugins.gradle.org/m2/

[pemistahl]

I'm not able to update the SSH plugin to 2.11.* because it's not available in the Gradle Plugin Portal.

Look here: https://mvnrepository.com/artifact/org.hidetake.ssh/org.hidetake.ssh.gradle.plugin

Version 2.11.* is only available at https://maven.eea.sk/artifactory/public/ which seems to be a repository for early access releases only. Is this a mistake?

Gradle is telling me:

> Could not resolve all files for configuration ':classpath'.
   > Could not resolve org.hidetake:core:2.11.2.
     Required by:
         project : > org.hidetake.ssh:org.hidetake.ssh.gradle.plugin:2.11.2
      > No matching variant of org.hidetake:core:2.11.2 was found. The consumer was configured to find a library for use during runtime, compatible with Java 8, packaged as a jar, and its dependencies declared externally, as well as attribute 'org.gradle.plugin.api-version' with value '8.1.1' but:
          - Variant 'apiElements' capability org.hidetake:core:2.11.2 declares a library, packaged as a jar, and its dependencies declared externally:
              - Incompatible because this component declares a component for use during compile-time, compatible with Java 11 and the consumer needed a component for use during runtime, compatible with Java 8
              - Other compatible attribute:
                  - Doesn't say anything about org.gradle.plugin.api-version (required '8.1.1')
          - Variant 'javadocElements' capability org.hidetake:core:2.11.2 declares a component for use during runtime, and its dependencies declared externally:
