I have only been a user of this awesome plugin for a short time, but I am hitting a wall with a need.

I am trying to dev a dsl groovy script that will create a job that uses the Mercurial scm, but also uses the new credentials ability. I know the groovy code to get the credentials ID, but I can't seem to get it working in through the Job DSL plugin. Can anyone help? I think the issue that I am running into may require a change to the plugin, but I would like to see what the community thinks.

Here is what I know will get me the credentials ID for the "foobar" credentials:

def creds = com.cloudbees.plugins.credentials.CredentialsProvider.lookupCredentials(
com.cloudbees.plugins.credentials.common.StandardUsernameCredentials.class,
Jenkins.instance,
null,
null
);
for (c in creds) {
if (c.description == "foobar")

}

But when I put this into a dsl, I get the following:

FATAL: No such property: com for class: test
