Jenkins Groovy 访问 属性 时出现 StackOverFlowError
Jenkins Groovy StackOverFlowError when accessing a property
我正在尝试编写一个小型作业 DSL，但在访问 class 属性.
时，我遇到了 java.lang.WhosebugError 错误
因此，甚至不需要复杂的脚本。看下面的脚本
class Komponente {
String name
Komponente(name) {
this.name = name
}
String getName() {
return this.name
}
String toString() {
return 'Klasse: Komponente (name: [' + this.name +'])'
}
}
Komponente komponente = new Komponente('Testkomponente')
println 'Erstellte Komponente: ' + komponente.getName()
当 运行 它在 Groovy web console 上时它工作正常，但是当 运行 它在我的 Jenkins 上时我得到：

如何在 Jenkins 上的 Groovy 脚本 运行 中访问 class 属性，而不会出现 WhosebugError 异常？
我的系统：
- Jenkins 版本为 2.73.3
- JobDSL 插件 1.68
- 订书机Groovy模块
org.kohsuke.stapler:stapler-groovy:1.250
- Apache Groovy
org.codehaus.groovy:groovy-all:2.4.11
我已经搜索过此错误消息，但我发现的所有 Jenkins 问题都已修复并至少在 2.7.1 中关闭，因此应该包含在我的 jenkins 版本中。
从您的 class 中删除 getName() 方法。当您指定 class 字段如 String name 时，您会立即获得方法 String getName() 和 void setName(String name)。
请记住 Jenkins Groovy 脚本执行环境与普通的 Groovy 有点不同（例如在 Groovy 控制台中）——Jenkins 使用 groovy-cps 执行环境。
在您的情况下，class org.kohsuke.groovy.sandbox.impl.Checker 导致错误 - 根据您的堆栈跟踪调用 Komponente.getName() 通过以下执行链触发 Komponente.getProperty() 方法：
at Komponente.getProperty(script)
at org.codehaus.groovy.runtime.InvokerHelper.getProperty(InvokerHelper.java:174)
at org.codehaus.groovy.runtime.ScriptBytecodeAdapter.getProperty(ScriptBytecodeAdapter.java:456)
at org.kohsuke.groovy.sandbox.impl.Checker.call(Checker.java:290)

at org.kohsuke.groovy.sandbox.impl.Checker.checkedGetProperty(Checker.java:292)
at org.kohsuke.groovy.sandbox.impl.Checker$checkedGetProperty.callStatic(Unknown Source)
at Komponente.getName(script:10)
并且 Komponente.getProperty() 触发了 Komponente.getName() 并且您 运行 进入了导致 WhosebugError.
的无限循环
当我将你的 class 复制到我的测试管道脚本时发生了类似的问题，这是我得到的堆栈跟踪：

没有你的那么直接，但也是一样的原因造成的。当我删除 String getName() 方法时，它按预期工作。它也应该对你有用。希望对你有帮助。
