第2行的here-document，以文件结尾分隔（需要`EOF _ $$'）

Question

下面是执行Shell脚本的Jenkins groovy代码：

height

---

以下是错误：

    BUILD_FULL = sh (
                script: '''
                        cat > manifest.yml << EOF_$$
                        ---
                        applications:
                        - name: xyz-api
                          instances: 1
                          memory: 1G
                        EOF_$$
                        ''',
                returnStatus: true
                ) == 0

line 9: warning: here-document at line 2 delimited by end-of-file (wanted `EOF_$$') 显示为：

manifest.yml

代替

                        ---
                        applications:
                        - name: xyz-api
                          instances: 1
                          memory: 1G
                        EOF_31892
