title: How to add git credentials to the build so it would be able to be used within a shell code?
body: <p>I've wrote the following Jenkinsfile:</p>
  
  <pre><code>node("master") {
   def artifactory_creds = 'XXXXXXX'
   def git_creds = 'XXXXXXX'
    java = docker.image('openjdk:8-jdk')
    java.pull()
    java.inside("-u root --ulimit core=99999999") {
        withCredentials([ // Use Jenkins credentials ID of artifactory
          [$class: 'UsernamePasswordMultiBinding', credentialsId: artifactory_creds, usernameVariable: 'A_USER', passwordVariable: 'A_PASS'],
          [$class: 'UsernamePasswordMultiBinding', credentialsId: git_creds, usernameVariable: 'G_USER', passwordVariable: 'G_PASS'] // Use Jenkins credentials ID of git
          ]) {

  <p>I'm able to run this build without this line:</p>
  
  <pre><code>[$class: 'UsernamePasswordMultiBinding', credentialsId: git_creds, usernameVariable: 'G_USER', passwordVariable: 'G_PASS'] 
  </code></pre>
  
  <p>But after adding this line, when I run the build, I get the following error:</p>
  
  <pre><code>org.jenkinsci.plugins.credentialsbinding.impl.CredentialNotFoundException: Credentials 'a378e16a-3d20-4465-aef1-b2bd233f15b6' is of type 'SSH Username with private key' where 'com.cloudbees.plugins.credentials.common.StandardUsernamePasswordCredentials' was expected
  </code></pre>
  
  <p>I'm trying to bind git username and password and use them within the '''sh''' code just like I used artifactory credentials.</p>
  
  <p>Anyone knows why I'm getting this error? The credentials I specified exist on the Jenkins server</p>
