如何使用Jenkins管道Groovy脚本检索当前工作区？

Question

我试图使用Groovy管道脚本获取Jenkins构建的当前工作区：

node('master') {
    // PULL IN ENVIRONMENT VARIABLES
    // Jenkins makes these variables available for each job it runs
    def buildNumber = env.BUILD_NUMBER
    def workspace = env.WORKSPACE
    def buildUrl = env.BUILD_URL

    // PRINT ENVIRONMENT TO JOB
    echo "workspace directory is ${workspace}"
    echo "build URL is ${env.BUILD_URL}"
}

它返回：

[Pipeline] Allocate node : Start
Running on master in /Users/Shared/Jenkins/Home/jobs/test/workspace
[Pipeline] node {
[Pipeline] echo
workspace directory is null
[Pipeline] echo
build URL is http://localhost:8080/job/test/5/
[Pipeline] } //node
[Pipeline] Allocate node : End
[Pipeline] End of Pipeline
Finished: SUCCESS

Answer 1

我认为您还可以在特定节点上执行pwd（）函数：

node {
    def PWD = pwd();
    ...
}

Answer 2

还没有包含该变量，所以您必须使用shell-out-read-file方法：

sh 'pwd > workspace'
workspace = readFile('workspace').trim()

或者（如果在主节点上运行）：

workspace = pwd()

Answer 3

对我来说，${WORKSPACE}甚至没有初始化变量WORKSPACE。
