Jenkins shell script unexpected end of file

Question

I started a new Jenkins server in the following way using Docker:

$ docker run -p 8081:8080 -p 50000:50000 -v "${PWD}"/jenkins:/var/jenkins_home -v /var/run/docker.sock:/var/run/docker.sock -d --name jenkins jenkins/jenkins:lts

I want to use it for a simple pipeline executing a shell script that is building another Docker container. This is why I am mounting the docker.sock as well. However, using a Jenkinsfile like the following:

pipeline {
    agent any

    stages {
        stage('Build') {
            steps {
                echo "####### builds: #######"
                sh "(exit 1) || true # whatever I write here, it always fails"
            }
        }
    }
}

I always get an error like:

Print Message -- ####### builds: ####### -- (self time 7ms)
####### builds: ####### 

Shell Script -- (exit 1) || true -- (self time 18s)
[X's Pipeline] Running shell script sh: 1: Syntax error: end of file unexpected (expecting "done")
process apparently never started in /var/jenkins_home/workspace/X's Pipeline@tmp/durable-f294beff 

replacing the sh line by any of the following did produce a similar error message and lead the build process to fail as well:

• sh "pwd;"
• sh "echo 'hello';"
• sh ./build.sh;"

• ​

  sh ```
  #!/bin/sh
  echo hello
  ```
  

• … I tried many more

But when I remove the sh line, the build succeeds. I have successfully done this before on other systems. Is there anything I am missing here?

It turned out, the name of the pipeline X's Pipeline has an '; and Jenkins is not escaping it or warning the user when using the GUI !!!!!!. After renaming the pipeline to X Pipeline it works just fine. Knowing this before could have saved me hours of trouble…
