      Description

      Both of these attempts results in the error 
       "docker build" requires exactly 1 argument.

      I believe this to be a bug since the docker.build works fine without any arguments.

      stage('Build image') {
        steps{
          sh """docker build -t my-image:dev --build-arg VAULT_TOKEN=${VAULT_TOKEN} ."""
        }
      } 

       

      stage('Build image') { 
        steps{ 
          docker.build "my-image:dev", "--build-arg VAULT_TOKEN=${VAULT_TOKEN} ."
        } 
      }  

      When looking at the pipeline output I can see the trailing "." is being removed from the docker.build step

      + docker build -t my-image:dev --build-arg VAULT_TOKEN=<token>
      "docker build" requires exactly 1 argument.
      See 'docker build --help'.
      
      Usage:  docker build [OPTIONS] PATH | URL | -

          If anyone has the same problem I was able to get around it by putting the commands into a shell script and just calling that

          more build_image.sh                                                                                                 [17:26:11]
