jenkins - 如何使用 Pipeline 引用 Jenkinsfile 目录？

Question

我有一个 groovy 文件，我想从 Jenkinsfile 运行。

IE。 load script.groovy
但是，如果它与 Jenkinsfile 存储在同一目录中，我不确定如何引用该文件。我正在从 git 加载 Jenkinsfile。我注意到它创建了一个名为 workspace@script 的文件夹.它不会将它放在工作区目录中。我可以对文件夹进行硬编码，但我不确定这方面的规则，再次 checkout 代码似乎有点多余。

java.io.FileNotFoundException: /opt/jenkins_home/jobs/my_job/workspace/script.groovy (No such file or directory)

默认情况下，它从工作区加载，而不是 workspace@script
我正在尝试将 BuildFlow 脚本转换为管道(工作流)脚本。但我发现，它不像复制和粘贴那么容易。

Jenkins 文件

node {

//get parameters from Job
def builds = builds.tokenize(",")
def ip_address_node = ip_address_node.trim()
def port_node = port_node.trim()
def branch = branch.trim()

git branch: branch, url: 'ssh://git@giturl/integration_bus.git'

load '../workspace@script/esb_deploybar_pipeline/deploy_esb.groovy'

}

有一种情况我没有看到任何人提到。当作业应该在 Jenkins 上运行时，如何加载 Groovy 脚本 代理/奴隶 ，而不是在 大师 .

由于 master 是从 SCM checkout Jenkins 管道项目的人， Groovy 脚本只能在主文件系统中找到 .所以虽然这会起作用:

node {       
    def workspace = pwd() 
    def Bar = load "${workspace}@script/Bar.groovy"
    Bar.doSomething()
}

这只是一个愉快的巧合，因为从 SCM 克隆管道的节点与尝试在其中加载 groovy 脚本的节点相同。但是，只需添加要在其上执行的不同代理的名称:

node("agent1"){
    def workspace = pwd() 
    def Bar = load "${workspace}@script/Bar.groovy"
    Bar.doSomething()
}

将失败，导致:

java.io.IOException: java.io.FileNotFoundException: /Jenkins/workspace/Foo_Job@script/Bar.groovy (No such file or directory)

这是因为这条路径:

/Jenkins/workspace/Foo_Job@script/

仅存在于主 Jenkins 盒子上。不在运行 的框中代理1 .

因此，如果您遇到此问题，请确保将 groovy 脚本从 master 加载到全局声明的变量中，以便代理可以使用它们:

def Bar
node {       
    def workspace = pwd() 
    if(isUnix()){
        Bar = load "${workspace}@script/Bar.groovy"
    }
    else{
        Bar = load("..\\workspace@script\\Bar.groovy")
    }
}
node("agent1"){
    Bar.doSomething()
}

注: 变量 用于在节点之间传递模块必须声明 外 节点 block 。
