我正在构建一个共享库,该库要具有类定义,例如:
class Kubernetes implements Serializable{
def script
Kubernetes(script){this.script = script}
def someMethod(){ ... }
}
我已将此类定义放在共享库git repo中,其路径为src/foo/bar/Kubernetes.groovy
。我正在jenkinsfile顶部的任何节点或管道指令外部使用以下步骤导入共享库:
library identifier: 'custom-lib@master', retriever: modernSCM(
[$class: 'GitSCMSource',
remote: '<my-git-remote>',
credentialsId: '<my-credentials-id>'])
import foo.bar.*
我已经验证了该库已被拉出,因为我可以引用在vars/
目录中创建的自定义DSL步骤。但是,当我编辑管道文件以创建该类的实例时,管道启动时会立即引发错误:
org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
WorkflowScript: 1276: unable to resolve class Kubernetes
@ line 1276, column 16.
def kube = new Kubernetes(this)

据我所知,在引发该错误之前,甚至没有执行库请求。但是据我所知,这正是Jenkins docs中如何演示此功能的。我需要采取其他措施才能正确加载库吗?

动态加载库不会将类直接导入到管道的类路径中-这就是为什么会出现此异常的原因,无论您引用的是完全合格的类名还是尝试导入(都会失败)。
Jenkins文档在library
步骤中介绍了如何加载库中定义的类:
您还可以通过在步骤的返回值上选择属性的全限定名称(例如属性)来加载库中定义的类,然后调用静态方法或调用构造函数,就像它们是名为
new
的方法一样:< / p>def utils = library('mylib').com.mycorp.jenkins.Utils.new(this) utils.handyStuff()
来源:https://jenkins.io/doc/pipeline/steps/workflow-cps-global-lib/
在您的情况下,它意味着要执行以下操作:
def kub = library( identifier: 'my-custom-library@master', retriever: modernSCM([
$class: 'GitSCMSource', remote: 'file:///var/jenkins_home/libraries', credentialsId: ''
])).foo.bar.Kubernetes.new(this)
println kub
这是我用于测试的本地示例库。当我运行管道时,它会成功并在控制台中显示以下输出:

我在Jenkins管道中没有使用太多动态库加载,实际上我使用的是全局库定义,例如:
在这种情况下,我可以使用以下方式加载库:
@Library('default_jenkins_libs@master') _
import foo.bar.Kubernetes
def kub = new Kubernetes(this)
println kub
此示例产生的输出与上面粘贴的输出类似。希望对您有所帮助。

您正在加载库吗?从Manage Jenkins»配置系统»Global Pipeline Libraries中,可以添加它,选择隐式加载一个引用。 此外,您可以在文件夹级别加载。
在非隐式加载的情况下,您必须添加
@Library('name-of-the-shared-lib@git-reference') _
到您的Jenkinsfile
完整的替代方法是documented at the pipeline docs
