我试图从Jenkins管道脚本中调用groovy脚本的方法，在这种情况下， java.lang.NullPointerException：无法在空对象上调用方法getBuildsByDomain（）。
下面是我的詹金斯脚本
pipeline{
agent any
environment{
def EARLIESTDATE = '0'
def LATESTDATE = '0'
}
parameters{
string(defaultValue: "", description: 'Mention the Jenkins Directory. Like Dev/testforlder or DEV', name: 'JENKINS_DIRECTORY')
string(defaultValue: "0", description: 'Enter the earliest date. Format: MM/dd/yyyy', name: 'EARLIEST_DATE')
string(defaultValue: "0", description: 'Enter the earliest date. Format: MM/dd/yyyy', name: 'LATEST_DATE')
}
stages{
stage("Getting Build Details"){
steps{
script{
def rootDir = pwd()
echo "LOG-->INFO-->Current Working Directory : ${rootDir}"
echo "LOG-->INFO-->JENKINS DIRECTORY : ${params.JENKINS_DIRECTORY}"
echo "LOG-->INFO-->EARLIEST DATE : ${params.EARLIEST_DATE}"

def buildDetails = load "${rootDir}/getJobDetails.groovy"

buildDetails.getBuildsByDomain(params.JENKINS_DIRECTORY, params.EARLIEST_DATE, params.LATEST_DATE)
}
}
}

def put(key, value) {
try {

this.dict[key]=value
printInfo()

println " #### ERROR #### --> " + exception.getMessage()
println " "

}
// Overridden toString() to have a meaningful display
String toString() {

}
在运行它时，我使用的参数是我在控制台输出下面得到的

Finished: FAILURE
我不是想知道我在做什么错误。请帮我调试一下。
答案 0 :(得分：2)
您唯一呼叫getBuildsByDomain
buildDetails.getBuildsByDomain(params.JENKINS_DIRECTORY...
表示buildDetails为空
通过加载buildDetails得到getJobDetails.groovy
但是getJobDetails.groovy脚本什么也不返回。
通常您应该以{{1}}
结尾答案 1 :(得分：0)
对于我来说，错误已经很清楚地解释了。
您拥有NPE，因为“ buildDetails”为空。 “ buildDetails”是加载“ $ {rootDir} /getJobDetails.groovy”的结果。
因此，我将从检查是否可以为Jenkins加载此文件开始。存在，权限等
