我正在构建一个Jenkins管道来自动验证共享库（来自Gerrit），方法是重用我们现在拥有的任何管道。
最初的想法应该很简单，即：

@Library( 'shared-libs@master' ) _
//                       |
//                       |
//         variable instead of hard code
//                       |
//                       v
@Library( "shared-libs@${refs_params}" ) _

库结构：

(root)
+- src                                # Groovy source files
|   +- org
|       +- jenkins
|           +- FooDefinition.groovy   # for org.jenkins.FooDefinition
|           +- BarDefinition.groovy   # for org.jenkins.BarDefinition
|           +- ...                    # for org.jenkins....
|       +- virtualization
|           +- PodDefinition.groovy   # for org.virtualization.PodDefinition
|           +- ...                    # for org.virtualization....
+- vars
|   +- foo.groovy                     # for global 'foo' variable
|   +- logger.groovy                  # for global 'logger' variable

对于常规流水线，我使用groovy共享库（在Manage Jenkins-〉Configure System-〉Global Pipeline Libraries中预设置），方法是：

@Library( 'shared-libs@master' ) _
import org.virtualization.PodDefinition

// generate pod
PodDefinition.runWith( ... ) {
  // pipeline content
}

确保refs/changes/x在指定参考规范：+refs/changes/*:refs/remotes/@{remote}/changes/*：

// works by using hard code `refs/changes/x/x/123`
@Library( 'shared-libs@refs/changes/x/x/123' ) _
import org.virtualization.PodDefinition

然而，当我使用GERRIT_REFSPEC时，由于WorkflowScript: @Library value ‘shared-libs@$GERRIT_REFSPEC’ was not a constant的原因，它不起作用，如下所示：

• @Library( 'shared-libs@${GERRIT_REFSPEC}' ) _
• @Library( 'shared-libs@${env.GERRIT_REFSPEC}' ) _
• @Library( 'shared-libs@${params.GERRIT_REFSPEC}' ) _

因此，我已经根据官方文档Extending with Shared Libraries修改了库的用法，将其修改为library( "shared-libs@${GERRIT_REFSPEC}" )，libs克隆工作正常，但import org.virtualization.PodDefinition失败：

library( "shared-libs@${GERRIT_REFSPEC}" )
// or
this._ = library( "shared-libs@${GERRIT_REFSPEC}" )
// or
this = library( "shared-libs@${GERRIT_REFSPEC}" )
// or
library( "shared-libs@${GERRIT_REFSPEC}" ) _

import org.virtualization.PodDefinition 

// WorkflowScript: 5: unable to resolve class org.virtualization.PodDefinition
//  @ line 3, column 1.
//   import org.virtualization.PodDefinition
//   ^
//
// 1 error

所以，我试过：

• load path/to/x.grovy

library( "shared-libs@${GERRIT_REFSPEC}" )
node( 'built-in' ) {
  load "../${env.JOB_BASE_NAME}@libs/<reivsion>/src/org/jenkins/FooDefinition.groovy"
  load "../${env.JOB_BASE_NAME}@libs/<reivsion>/src/org/jenkins/BarDefinition.groovy"
  load "../${env.JOB_BASE_NAME}@libs/<reivsion>/src/org/virtualization/PodDefinition.groovy"
}

// --- shows thrid party libs import failure ---
// org.jenkinsci.plugins.workflow.cps.CpsCompilationErrorsException: startup failed:
// Script7.groovy: 3: unable to resolve class com.cwctravel.hudson.plugins.extended_choice_parameter.ExtendedChoiceParameterDefinition
//  @ line 3, column 1.
//    import com.cwctravel.hudson.plugins.extended_choice_parameter.ExtendedChoiceParameterDefinition
//    ^
//
// 1 error

个字符串

• def x = library() org.x.x（从Importing class from git - unable to resolve class获取提示）：它将不再精确地重用现有流水线，而且几十个groovy文件也给命名

def a = library( "shared-libs@${GERRIT_REFSPEC}" ) org.jenkins.FooDefinition.groovy
def b = library( "shared-libs@${GERRIT_REFSPEC}" ) org.jenkins.BarDefinition.groovy
def c = library( "shared-libs@${GERRIT_REFSPEC}" ) org.jenkins.xxx.groovy
def d = library( "shared-libs@${GERRIT_REFSPEC}" ) org.virtualization.PodDefinition.groovy
def e = library( "shared-libs@${GERRIT_REFSPEC}" ) org.virtualization.xxx.groovy

带来了困难

• 第一个

因此，我不知道下一步应该做什么，是将"shared-libs@${GERRIT_REFSPEC}"“更改”为常量以使用@Library(...) _，还是使用library(...)导入src/**下的所有库
顺便说一句，这里我已经尝试过将变量“转换”为常量的方法：

Object.metaclass.SHARED_LIBS = "shared-libs@${GERRIT_REFSPEC}"
@Library( SHARED_LIBS ) _

// or
class SHARED_LIBS {
  final String REFSPEC = "shared-libs@${GERRIT_REFSPEC}"
}
@Library( SHARED_LIBS.REFSPEC ) _

// or
import groovy.transform.Field
@Field final String SHARED_LIBS = "shared-libs@${GERRIT_REFSPEC}"
@Library( SHARED_LIBS ) _

// or
def bindings = new Binding()
bindings.setVariable("SHARED_LIBS", "shared-libs@${GERRIT_REFSPEC}")
@Library( SHARED_LIBS ) _

// or
withEnv([ 'SHARED_LIBS=shared-libs@${GERRIT_REFSPEC}' ]) {
  @Library( SHARED_LIBS ) _
}
