Hello,

In the plugin wiki page, it is mentioned that we need Jenkins 1.609 and and the docker-commons plugin 1.0 if we want to use the Docker Custom Build Env plugin.

Two others dependencies are listed as optional: maven-plugin 2.12 & dockerhub-notification 1.0.

I tried to install your plugin on Jenkins 1.609.3 with docker-commons installed and I get the following error at Jenkins startup :

Warning: Failed to scout com.cloudbees.jenkins.plugins.docker_build_env.MavenPluginHelper
java.lang.InstantiationException: java.lang.NoClassDefFoundError: hudson/maven/TcpSocketHostLocator

Note that as I didn't explicitly installed the maven-plugin, Jenkins was using the one embedded in 1.609.3, maven-plugin 2.7.1.

Then I installed the maven-plugin 2.12 and your plugin was working fine: I didn't get any error at Jenkins startup.

So could you please update the wiki page of your plugin to specify that maven-plugin 2.12 is not and optional dependency ?

Regards,
Pierre
