Jenkins groovy.lang.MissingPropertyException：没有这样的属性：对于类：Script1

Question

The purpose of this program is to replace all TFS user's password. It works if I directly use the userid and password inside the code, but fails with this error when I convert it to a paramaterized build.

Answer 1

引发groovy.lang.MissingPropertyException的原因之一是当您尝试访问其范围之外的变量或您尚未定义该变量时。

Answer 2

I guess you may need to use Field annotation, on the mentioned property. Please also have a look here .

Answer 3

You need to check if the parameter is defined before accessing it:

if ( System.getenv('VARIABLE') ) {
  println "VARIABLE parameter exists, and its value is: " + VARIABLE
}

These methods might also work in the groovy script:

• binding.variables.containsKey('VARIABLE')
• currentBuild.buildVariableResolver.resolve('VARIABLE')
• build.environment.get('VARIABLE')
