Jenkins does not recognize command sh? : <p>I've been having a lot of trouble trying to get a Jenkinsfile to work. 
I've been trying to run this test script:</p>

<pre><code>#!/usr/bin/env groovy
node {
    stage('Build') {
        echo 'Building....'
        // Create virtualenv
        sh 'echo "hi"'
    }
    stage('Test') {
        echo 'Building....'
    }
    stage('Deploy') {
        echo 'Deploying....'
    }
}
</code></pre>

<p>But I keep getting this error when trying to build:</p>

<pre><code>Warning: JENKINS-41339 probably bogus PATH=/usr/lib64/ccache:/usr/lib64/ccache:$PATH; perhaps you meant to use ‘PATH+EXTRA=/something/bin’?
[test-job-jenkinsfile-pipeline] Running shell script
nohup: failed to run command `sh': No such file or directory
</code></pre>

<p>I updated all the pipeline plugins to the latest version and still run into this error. Any help?</p>
