在詹金斯管道中使用嵌套命令替换sh步骤

我试图在使用相关内部文件夹的符号链接进行归档之前，将结果目录展平，该链接首先遍历在运行时确定的一堆变量路径名。我从SO答案中选择的命令替换方法似乎不太正确。

问题：是否有一条规则，如何正确地从我不知道的Jenkins管道步骤中转义命令替换链？

post {
  always {   
    sh """
    echo 'Link to inner output result folder to make the artifacts more shallow'
    echo ln -sf dirname find $output_dir -name $jUnitResult $WORKSPACE/$output_dir_inner
    ln -sf $(dirname $(find ${output_dir} -name ${jUnitResult})) $WORKSPACE/$output_dir_inner
    """
    archiveArtifacts output_dir_inner
  }
}

我在尝试时看到类似的失败

ln -sf $(dirname $(find $output_dir -name $jUnitResult)) $WORKSPACE/$output_dir_inner

org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
WorkflowScript: 49: illegal string body character after dollar sign;
   solution: either escape a literal dollar sign "\$5" or bracket the value expression "${5}" @ line 49, column 13.
               sh """
               ^

回答：

解决这个问题的几个有趣策略

将长sh脚本分解为具有返回值的不同功能块

http://codingdict.com/questions/82048

使用反斜杠转义嵌套的shell命令\$，

sh """
    \$(echo TEST this subshell \$(ls .))
"""
