什么是“由文件末尾分隔”(希望‘`EOF’)

Question

我试着执行以下几行-

   sh """
      #!/bin/bash
      cd ${WORKSPACE}

      cat << EOF > build.sh
      #!/bin/bash
      mkdir wsbuildlinux
      cd wsbuildlinux
      cmake3 ../../wiresharkbuild_linux
      make
      EOF

      chmod 755 build.sh

      # run container and build wireshark
      ./build-env/run-wireshark-env ./build.sh
    """

这是“build.sh”的内容-

  #!/bin/bash
  mkdir wsbuildlinux
  cd wsbuildlinux
  cmake3 ../../wiresharkbuild_linux
  make
  EOF

  chmod 755 build.sh

  # run container and build wireshark
  ./build-env/run-wireshark-env ./build.sh

但我一直在跟踪错误-

/opt/cvsdirs/crdbuilds/jenkins/slave/workspace/Wireshark_Wireshark_trunk@tmp/durable-f510f070/script.sh: line 17: warning: here-document at line 5 delimited by end-of-file (wanted `EOF')

我不知道这个错误意味着什么，也不知道如何解决它。你能给我一些建议吗？

EOF令牌必须位于行的开头。

sh """
      #!/bin/bash
      cd ${WORKSPACE}

      cat << EOF > build.sh
      #!/bin/bash
      mkdir wsbuildlinux
      cd wsbuildlinux
      cmake3 ../../wiresharkbuild_linux
      make
EOF

      chmod 755 build.sh

      # run container and build wireshark
      ./build-env/run-wireshark-env ./build.sh
    """
