What is "delimited by end-of-file (wanted `EOF')"-CodePudding

I am trying to execute following lines-

   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
    """

and here is the content of "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

But I keep getting following error-

/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')

I have no idea what this error means and how to resolve it. Could you please give some advice on this

CodePudding user response：

The EOF token has to be at the beginning of the line.

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

      cat << EOF > build.sh
      #!/bin/bash

      cd wsbuildlinux
      cmake3 ../../wiresharkbuild_linux
      make
EOF

      chmod 755 build.sh

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