错误：java.io.NotSerializableException:groovy.util.slurpersupport.Attributes

我在Jenkinsfile函数中使用@NonCPS，因为我需要获取XML use XmlSlurper上的属性，即使使用@NonCPS注释，我仍然会得到java.io.NotSerializableException错误

下面是我的代码

    @Field prBranchCoverage
    @NonCPS
def xmlCovergeParse(CoverageXml) {
    println "start coverage"
    def prParser = new XmlSlurper()
    prParser.setFeature("http://apache.org/xml/features/disallow-doctype-decl", false) 
    prParser.setFeature("http://apache.org/xml/features/nonvalidating/load-external-dtd", false);
    def prCovergeDoc = prParser.parseText(CoverageXml)
    def branchCoverage = prCovergeDoc['@line-rate']
    return branchCoverages
}
stage('Pr coverage ') {
                sh "mvn -V -B -U cobertura:cobertura -PcodehausCoverage -Dmaven.test.failure.ignore=true -DskipWeaving=true test"
        publishTestResults cobertura: [archive: true,pattern: "**/target/site/cobertura/coverage.xml"]
        def CoverageXml = readFile file: './target/site/cobertura/coverage.xml'
        def prBranchCoverage = xmlCovergeParse(CoverageXml)
        echo "start coverage"

        println prBranchCoverage

            }

我得到的错误是：

Error: java.io.NotSerializableException: groovy.util.slurpersupport.Attributes
an exception which occurred:
    in field com.cloudbees.groovy.cps.impl.BlockScopeEnv.locals
    in object com.cloudbees.groovy.cps.impl.BlockScopeEnv@72e69aed

有人能帮忙吗？

您的方法

xmlCovergeParse（CoverageXml）

返回不可序列化的对象

jenkins要求管道中的所有变量都为，因为下一步可以在其他节点上执行，而不是上一步。因此，为了在节点之间传输变量，它们将被序列化

只需在方法

xmlCovergeParse
