我有一个具有多个阶段的 Jenkins 管道,例如:
node("nodename") {
stage("Checkout") {
git ....
}
stage("Check Preconditions") {
...
if(!continueBuild) {
// What do I put here? currentBuild.xxx ?
}
}
stage("Do a lot of work") {
....
}
}
如果不满足某些先决条件并且没有实际工作要做,我希望能够取消(而不是失败)构建。我该怎么做?我知道
currentBuild
变量可用,但我找不到它的文档。
error
步骤使构建停止:
if (!continueBuild) {
currentBuild.result = 'ABORTED'
error('Stopping early…')
}
在阶段视图中,这将显示构建在此阶段停止,但构建整体将被标记为中止,而不是失败(请参阅构建 #9 的灰色图标):
经过一些测试,我想出了以下解决方案:
def autoCancelled = false
try {
stage('checkout') {
...
if (your condition) {
autoCancelled = true
error('Aborting the build to prevent a loop.')
}
}
} catch (e) {
if (autoCancelled) {
currentBuild.result = 'ABORTED'
echo('Skipping mail notification')
// return here instead of throwing error to keep the build "green"
return
}
// normal error handling
throw e
}
这将导致以下舞台视图:
如果你不喜欢失败的阶段,你必须使用return。但请注意,您必须跳过每个阶段或包装器。
def autoCancelled = false
try {
stage('checkout') {
...
if (your condition) {
autoCancelled = true
return
}
}
if (autoCancelled) {
error('Aborting the build to prevent a loop.')
// return would be also possible but you have to be sure to quit all stages and wrapper properly
// return
}
} catch (e) {
if (autoCancelled) {
currentBuild.result = 'ABORTED'
echo('Skipping mail notification')
// return here instead of throwing error to keep the build "green"
return
}
// normal error handling
throw e
}
结果:
您还可以使用自定义消息而不是局部变量:
final autoCancelledError = 'autoCancelled'
try {
stage('checkout') {
...
if (your condition) {
echo('Aborting the build to prevent a loop.')
error(autoCancelledError)
}
}
} catch (e) {
if (e.message == autoCancelledError) {
currentBuild.result = 'ABORTED'
echo('Skipping mail notification')
// return here instead of throwing error to keep the build "green"
return
}
// normal error handling
throw e
}
我发现的最优雅的方式: 注意,它需要在
Manage Jenkins -> In process script approval
页面批准方法签名
currentBuild.result = "ABORTED"
throw new org.jenkinsci.plugins.workflow.steps.FlowInterruptedException(hudson.model.Result.ABORTED)
如果您只想标记构建/阶段结果但继续下一步和阶段,您可以使用:
steps{
script{
echo "Hello"
catchError(buildResult: 'ABORTED', stageResult: 'ABORTED') {
error("Your abortion reason goes here")
}
}
}
如果您能够批准 FlowInterruptedException 的构造函数,那么您可以执行以下操作:
throw new FlowInterruptedException(Result.ABORTED, new UserInterruption(getCurrentUserId()))
您可以将文件添加到共享库存储库中
var/abortError.groovy
:
import org.jenkinsci.plugins.workflow.steps.FlowInterruptedException
import jenkins.model.CauseOfInterruption.UserInterruption
def call(message)
{
currentBuild.displayName = "#${env.BUILD_NUMBER} $message"
echo message
currentBuild.result = 'ABORTED'
throw new FlowInterruptedException(Result.ABORTED, new UserInterruption(env.BUILD_USER_ID))
}
然后你就可以这样使用它(导入库后):
abortError("some message")
请注意,如果您在控制台日志中看到以下错误:
org.jenkinsci.plugins.scriptsecurity.sandbox.RejectedAccessException: Scripts not permitted to use new org.jenkinsci.plugins.workflow.steps.FlowInterruptedException hudson.model.Result jenkins.model.CauseOfInterruption[]
您需要按照链接表单日志并批准安全例外。
我们使用的东西是:
try {
input 'Do you want to abort?'
} catch (Exception err) {
currentBuild.result = 'ABORTED';
return;
}
最后的“返回”确保不再执行任何代码。
我是用声明式的方式处理的,如下图:
基于 catchError 块,它将执行 post 块。 如果后期结果属于失败类别,则将执行错误块以停止即将到来的阶段,例如生产、预生产等。
pipeline {
agent any
stages {
stage('Build') {
steps {
catchError {
sh '/bin/bash path/To/Filename.sh'
}
}
post {
success {
echo 'Build stage successful'
}
failure {
echo 'Compile stage failed'
error('Build is aborted due to failure of build stage')
}
}
}
stage('Production') {
steps {
sh '/bin/bash path/To/Filename.sh'
}
}
}
}
受到所有答案的启发,我将所有内容整合到一个脚本化管道中。请记住,这不是声明式管道。
要使此示例正常工作,您需要:
我的想法是,如果管道是“重播”而不是通过“运行按钮”启动(在 Jenskins BlueOcean 的分支选项卡中),则中止管道:
def isBuildAReplay() {
// https://stackoverflow.com/questions/51555910/how-to-know-inside-jenkinsfile-script-that-current-build-is-an-replay/52302879#52302879
def replyClassName = "org.jenkinsci.plugins.workflow.cps.replay.ReplayCause"
currentBuild.rawBuild.getCauses().any{ cause -> cause.toString().contains(replyClassName) }
}
node {
try {
stage('check replay') {
if (isBuildAReplay()) {
currentBuild.result = 'ABORTED'
error 'Biuld REPLAYED going to EXIT (please use RUN button)'
} else {
echo 'NOT replay'
}
}
stage('simple stage') {
echo 'hello from simple stage'
}
stage('error stage') {
//error 'hello from simple error'
}
stage('unstable stage') {
unstable 'hello from simple unstable'
}
stage('Notify sucess') {
//Handle SUCCESS|UNSTABLE

}
} catch (e) {

if(currentBuild.result == 'ABORTED'){
//Handle ABORTED

throw e
}else{
//Handle FAILURE

throw e
}
} finally {
echo 'I will always say Hello again!'
}
}
主要技巧是实现中止状态的行顺序:
currentBuild.result = 'ABORTED'
error 'Biuld REPLAYED going to EXIT (please use RUN button)'
首先设置状态然后抛出异常。
在 catch 块中两者都有效:
currentBuild.result
currentBuild.currentResult
您可以转到 Jenkins 的脚本控制台并运行以下命令来中止挂起/任何 Jenkins 作业构建/运行:
Jenkins .instance.getItemByFullName("JobName")
.getBuildByNumber(JobNumber)
.finish(hudson.model.Result.ABORTED, new java.io.IOException("Aborting build"));
Executor.interrupt(Result)
方法是我能找到的最干净、最直接的方法来提前停止构建并选择结果。
script {
currentBuild.getRawBuild().getExecutor().interrupt(Result.NOT_BUILT)
sleep(1) // Interrupt is not blocking and does not take effect immediately.
}
您可以为此使用任何 Result 常量,但根据您“取消”的愿望,因为“没有实际工作要做”,我认为 NOT_BUILT 结果是最合适的。这具有向连接的集成(例如 Bitbucket)发出信号的额外优势,即构建应被忽略并且不计为失败。
