Cannot load files using the jenkins master node when using pipeline remote file loader plugin

XMLWordPrintable

      When using the pipeline-remote-loader-plugin to load files from a github repository using the master node Jenkins start looking for a new executioner as if for some reason it cannot use master to load the files. Since I have openstack-cloud-agents plugin it is trying to launch a new agent and use that node to load the files instead of just using master, which is the node specified.

      This is my pipeline code:

      def common, osa
stage 'Sandbox'
node('master') {
    println "Testing master"
    sh 'hostname'
    fileLoader.withGit('https://github.com/osic/qa-jenkins-onmetal.git', 'master', null, '') {
        common = fileLoader.load('jenkins/common.groovy');
        osa = fileLoader.load('jenkins/osa_onmetal.functions.groovy');
    }
}

      And this is the console output:

      As shown in the console output, when trying to load the external files, instead of using master, which is the node specified with the label, it tries to launch a new agent:

      Waiting for next available executor
      Running on ci-openstack-agent-xlarge-7648 in /home/ubuntu/workspace/sandbox

      This code was working fine a few days ago, it was loading the files correctly on the master node.
