Question

我正在尝试从Jenkinsfile运行管道作业（使用Groovy代码）但是我收到以下错误 -

java.io.NotSerializableException: groovy.util.slurpersupport.NodeChildren
    at org.jboss.marshalling.river.RiverMarshaller.doWriteObject(RiverMarshaller.java:860)
    at org.jboss.marshalling.river.RiverMarshaller.doWriteObject(RiverMarshaller.java:778)

    at sun.reflect.GeneratedMethodAccessor101.invoke(Unknown Source)
...

我想要执行的代码是 -

def getDataVersionFromNexus() {
    def user = params.nexusUser
    def password = params.nexusPassword    
    ...

    def oldVersion = -1
    print output
    if (!output.isEmpty()) {        
        def xmlContent = new XmlSlurper().parseText(output)
        oldVersion = "${xmlContent.versioning.release}"
    }

    return oldVersion
}

我试图将方法注释为@NonCPS（如类似的SO帖子所示）但是我没有得到正确的输出。

Answer 1

尝试将此值作为列表复制到ArrayList，然后使用。例如，像这样：

tmp = xmlContent.versioning.release.toList()
list = new ArrayList()
for (i = 0; i != tmp.size(); i += 1) {
    list.add(tmp.get(i))
}
oldVersion = list.get(0)
