在Jenkins管道后阶段无法传递变量

Question

场景:我无法在后期步骤中传递参数。下面是错误 post {Script{ sh“count=ca changes.txt | wc -l echo ${count}如果[ ${count} == 0 ]；然后回显‘条件成功’否则回送‘条件而不是成功’fi”“}‘}’

错误：

16:24:38 email-2运行shell脚本16:24:39 ++ cat changes.txt 16:24:39 ++ wc -l 16:24:39 + count=7管道}管道/脚本错误执行成功后条件: groovy.lang.MissingPropertyException: No此类属性：$count表示类: WorkflowScript at org.codehaus。groovy.runtime.ScriptBytecodeAdapter.unwrap(ScriptBytecodeAdapter.java:53)

这应该是可行的：

pipeline {
    agent any
    stages {
        stage ('test') {
            steps {
                script {
                    sh """
                       echo "1" > changes.txt
                       count=\$(cat changes.txt | wc -l)
                       echo \$count
                       if [ \$count = 0 ]; then
                            echo 'condition success'  
                       else
                            echo 'condition not success'
                       fi
                       """
                }
            }
        }
    }
}

输出：
