Failure With :publishPlugins When Upgrading to 2.6

I’ve been successful in the past with publishing to the portal. Since upgrading from Gradle 2.4 to 2.6 I’m now getting the following error.

~/projects/gradle-syntastic-plugin(master ✔) gradle publishPlugin   
:publishPlugins FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':publishPlugins'.
> org/gradle/mvn3/org/apache/maven/project/MavenProject

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

BUILD FAILED

And the stacktrace is:


* Exception is:
org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':publishPlugins'.
