Gradle sync fails after adding plugin on a brand new android library

[provenstyle]

Unable to load class 'org.gradle.api.capabilities.Capability'. Possible causes for this unexpected error include:

• Gradle's dependency cache may be corrupt (this sometimes occurs after a network connection timeout.) Re-download dependencies and sync project (requires network)
• The state of a Gradle build process (daemon) may be corrupt. Stopping all Gradle daemons may solve this problem. Stop Gradle build processes (requires restart)
• Your project may be using a third-party plugin which is not compatible with the other plugins in the project or the version of Gradle requested by the project.

In the case of corrupt Gradle processes, you can also try closing the IDE and then killing all Java processes.

Please add the Grade and the plugin version. Maybe your Gradle version is incompatible with the plugin.

You are right. I realize the importance of the compatibility table now. I was trying to use Gradle 4.6 with 3.6.2 and they are incompatible. Thank you.

No problem. Unfortunately it's important, because maven-publish is an incubation feature in Gradle. It will be stable in Gradle 5.0
