      I write a dead simple Dockerfile

      FROM openjdk:8-jdk-alpine
      ENTRYPOINT "java"
      

      I write a dead simple declarative pipeline

      pipeline {
          agent { dockerfile true }
          stages {
              stage('Dead Simple') {
                  steps {
                      checkout scm
                  }
              }
          }
       }

      I get an error.

      I get the same error with 

      pipeline {
          agent { docker { image 'openjdk:8-jdk-alpine' } }
          stages {
              stage('Dead Simple') {
                  steps {
                      checkout scm
                  }
              }
          }
      }

      The error is

      ERROR: The container started but didn't run the expected command. Please double check your ENTRYPOINT does execute the command passed as docker run argument, as required by official docker images (see https://github.com/docker-library/official-images#consistency for entrypoint consistency requirements).
      Alternatively you can force image entrypoint to be disabled by adding option `--entrypoint=''`.
      

      I cannot pass --entrypoint to the run command, it's jenkins that calls it

      a bit more logs :
