我在本地受信任的环境中运行Jenkins，在其中尝试运行此管道。此Jenkinsfile被检入git。

#!groovy
node('master') {
    def ver = pomVersion()
    echo "Building version $ver"
}

def pomVersion(){
    def pomtext = readFile('pom.xml')
    def pomx = new XmlParser().parseText(pomtext)
    pomx.version.text()
}

运行构建的前几次，我需要手动批准更改（Jenkins-> Mange
Jenkins->进程内脚本批准）。现在，我收到此异常，没有什么可以批准的。我要做的就是解析XML文件。这些安全检查能否完全绕过管道构建？
