当我尝试在Jenkins控制台中执行以下Groovy脚本时，会发生以下错误。
import hudson.model.*
/* removed as per comments
// get current thread / Executor
def thr = Thread.currentThread()
// get current build
import hudson.model.*
def build = thr?.executable
*/
// get parameters
def parameters = build?.actions.find{ it instanceof ParametersAction }?.parameters
parameters.each {
println "parameter ${it.name}:"
println it.dump()
println "-" * 80
}
// ... or if you want the parameter by name ...
def hardcoded_param = "FOOBAR"
def resolver = build.buildVariableResolver
def hardcoded_param_value = resolver.resolve(hardcoded_param)
println "param ${hardcoded_param} value : ${hardcoded_param_value}"
这取自Use Jenkins > Jenkins Script Console > Parameterized System Groovy script。
错误表明它包含一些缺失的属性：

我已经尝试Running Groovy command from Jenkins using Groovy script plugin，但我的情况不合适。
答案 0 :(得分：1)
假设您正在使用“系统Groovy脚本”，那么，如果我正确地读取code，那么构建变量应该已经可用，并且您不需要通过没有的Thread获取它属性“executable”导致崩溃。
这也与here显示的示例一致，build变量只是神奇地存在。
答案 1 :(得分：1)
如果我添加构建步骤→执行系统Groovy脚本→ Groovy命令：
import hudson.model.*
// get parameters
def parameters = build?.actions.find{ it instanceof ParametersAction }?.parameters
parameters.each {
println "parameter ${it.name}:"
println it.dump()
println "-" * 80
}
// ... or if you want the parameter by name ...
def hardcoded_param = "FOOBAR"
def resolver = build.buildVariableResolver
def hardcoded_param_value = resolver.resolve(hardcoded_param)
println "param ${hardcoded_param} value : ${hardcoded_param_value}"
输出是：
param FOOBAR value : null
这是可以理解的，因为${FOOBAR}的值应该来自哪里？
如果我选择☑此版本已参数化→添加参数→字符串参数：
FOOBAR FOOBAR_value 输出是：
parameter FOOBAR:
<hudson.model.StringParameterValue@a6648c13 value=FOOBAR_value name=FOOBAR description=>
--------------------------------------------------------------------------------
param FOOBAR value : FOOBAR_value
