If I remove the credentials via Jenkins web interface and try to converge, it works, but if I try to converge again, with the credential already created, it doesn't. Am I missing something ?

Thank you very much!

Workaround for now, to remove the credentials during each chef run and then recreate it:

jenkins_script 'hack around issue 591' do
  command <<-EOH
    import jenkins.model.*
    import com.cloudbees.plugins.credentials.*;
    import com.cloudbees.plugins.credentials.*
    import com.cloudbees.plugins.credentials.common.*
    import com.cloudbees.plugins.credentials.domains.*;
    global_domain = com.cloudbees.plugins.credentials.domains.Domain.global()
    credentials_store =
      Jenkins.instance.getExtensionList(
        'com.cloudbees.plugins.credentials.SystemCredentialsProvider'
      )[0].getStore()
    id_matcher = CredentialsMatchers.withId("REPLACE_ME_WITH_CREDENTIAL_ID")
    available_credentials =
      CredentialsProvider.lookupCredentials(
        StandardUsernameCredentials.class,
        Jenkins.instance,
        hudson.security.ACL.SYSTEM,
        new SchemeRequirement("ssh")
      )
    existing_credentials =
      CredentialsMatchers.firstOrNull(
        available_credentials,
        id_matcher
      )
    if(existing_credentials != null) {
      credentials_store.removeCredentials(
        global_domain,
        existing_credentials
      )
    }
  EOH
end

any updates on this bug?

[stuszynski]

@Poohblah https://github.com/chef-cookbooks/jenkins/pull/597 works fine to me as a workaround

[jayhendren]

I meant updates from the project maintainers. I would really like to see #597 merged.

[jayhendren]

I've got what I believe to be a better workaround. Rather than delete and re-create the credentials every time, check to see if credentials.xml contains the credentials:

jenkins_private_key_credentials 'mycreds' do
  id 'mycreds'
  private_key key
  not_if do
    credentials_file = '/var/lib/jenkins/credentials.xml'
    matcher = '<description>Credentials for mycreds - created by Chef</description>'
    re = /#{Regexp.quote matcher}/
    File.exist?(credentials_file) && File.readlines(credentials_file).grep(re).any?
  end
end
