Jenkins XmlParser报告未找到根节点属性的此类字段 [英] Jenkins XmlParser reports No such field found for attribute for root node
问题描述
我有一个项目，该项目具有以下XML文件(Cordova项目的config.xml)...
I have a project that has the following XML file (config.xml for a Cordova project) ...
<?xml version='1.0' encoding='utf-8'?>
<widget android-versionCode="16" id="com.mycomp.myapp" ios-CFBundleVersion="15" version="1.3.0.b4" windows-packageVersion="1.2.6.0" xmlns="http://www.w3.org/ns/widgets" xmlns:cdv="http://cordova.apache.org/ns/1.0">
<name>My App</name>
<description>My app description</description>
<author>mycom.com.au</author>
....
我要做的就是读取根元素(widget)的version属性值(为我提供字符串1.3.0.b4).遵循此处的示例使用.@获取属性.
All I want to do is read the value of the version attribute (to give me the string 1.3.0.b4) of the root element (widget). Following the example here where it says to use the .@ to get an attribute.
我的Jenkins文件脚本中包含以下内容...
I have the following in my Jenkins file script...
script {
def xml = readFile "${env.WORKSPACE}/config.xml"
def rootNode = new XmlParser().parseText(xml)
def version = rootNode.@version
echo 'version is...'
echo version
但是当我运行它时，出现以下错误.
But when I run it, I get the following error..
org.jenkinsci.plugins.scriptsecurity.sandbox.RejectedAccessException: No such field found: field groovy.util.Node version
at org.jenkinsci.plugins.scriptsecurity.sandbox.groovy.SandboxInterceptor.unclassifiedField(SandboxInterceptor.java:425)

at org.kohsuke.groovy.sandbox.impl.Checker.checkedGetAttribute(Checker.java:375)
at com.cloudbees.groovy.cps.sandbox.SandboxInvoker.getAttribute(SandboxInvoker.java:37)
我已经尝试过rootNode.@version(如上所述)rootNode[0].@version和rootNode[3].@version，但是没有任何效果.
I have tried rootNode.@version (as above) rootNode[0].@version and rootNode[3].@version but nothing works.
有人对以上问题有任何想法吗?
Does anyone have any idea of whats wrong with the above?
预先感谢
如果我使用以下内容...
If I use the following...
def xml = readFile "${env.WORKSPACE}/config.xml"
def rootNode = new XmlParser().parseText(xml)
def version = rootNode.text()
echo 'version is...'
echo version
它打印出My app description有点奇怪(它跳到了描述节点)
it prints out My app description which is a bit weird (it jumps down to the description node)
我尝试使用以下内容.
def rootNode = new XmlSlurper().parse("${env.WORKSPACE}/config.xml")
def version = rootNode.@'version'
但是我仍然遇到类似的错误...
but I still get a similar error...

如果我呼叫echo rootNode.text()，似乎再次只是打印出,widget主标签内的前3个标签的内容，即My AppMy app descriptionmycom.com.au.
If I call echo rootNode.text(), once again it seems to just print out the contents of the first 3 tags inside the main ,widget tag, i.e. My AppMy app descriptionmycom.com.au.
推荐答案
在能够修改属性的上下文中，我进行了更多测试，并发现使用[]访问时，属性的@选择器实际上是有效的.看来这会导致您使用詹金斯(getAt和putAt)认可的不同方法.
I tested some more in context of being able to also modify the attribute, and found out when using the [] access, the @ selector for attributes actually works. It seems this leads to use different methods under the hood which you can approve in jenkins (getAtand putAt) .
我们可以简单地使用
def rootNode = new XmlParser().parseText(xml)
println rootNode['@version']
原始答案:
Original Answer:
There seems some bug regarding the direct access to the attributes with the @ selector on the groovy.util.Node object with the script sandbox.
一种解决方法是使用.attributes()方法获取完整的Map属性，并通过如下所示的键访问值:
A workaround is to use the .attributes() method to get the full Map of attributes, and access the value via the key like the following:
def rootNode = new XmlParser().parseText(xml)
println rootNode.attributes()['version']
这将使首次运行失败，并提示您批准使用method groovy.util.Node attributes，但是一旦获得批准，该功能就会生效.
This will fail the first run and promt you to approve the use of method groovy.util.Node attributes, but once approved will work.
