无法发布Grails插件

Question

I am trying to publish a new version of the Spring Security OAuth2 Provider grails plugin (2.0-RC1), and it seems to upload the artifacts correctly (see here ), but the plugin page on grails.org is not updated. Here is the output from publishing - I'm not sure what do about the error honestly:

~>grailsw publish-plugin --grailsCentral --stacktrace

I'm using the release plugin version 3.0.1 and grails 2.3.8. I'm also on Windows 7 x64 with Java 7 x64.

Answer 1

Found the solution after finally taking the time to dig into the publish plugin code. The problem was actually that I had a newer version of the rest-client-builder overriding the version bundled with the release plugin. I was using version 2.0.1 instead of 1.0.3.

Changing the rest-client-builder plugin version to 1.0.3 fixed the issue (using release plugin 3.0.1).
