无法将参数从一个管道作业传递到另一个管道任务

Question

编辑问题：我正在尝试运行一个简单的管道作业，该作业会触发另一个管道作业并发送参数值。我在下面的示例中尝试了一个简化的用例

Piepeline-母

pipeline{
agent any
options {
buildDiscarder logRotator(artifactDaysToKeepStr: '', artifactNumToKeepStr: '', daysToKeepStr: '', numToKeepStr: '5')
}
stages {
stage('Invoke sample_pipleline') {
steps {
CommitID = 'e2b6cdf1e8018560b3ba51cbf253de4f33647b5a'
Branch = "master"
input id: 'Environment', message: 'Approval', parameters: [choice(choices: ['FRST', 'QA', 'PROD'], description: '', name: 'depServer')], submitter: 'FCMIS-SFTP-LBAAS', submitterParameter: 'user'
build job: 'simple_child', 
parameters: [string(name: 'CommitID', value: 'e2b6cdf1e8018560b3ba51cbf253de4f33647b5a'),string(name: 'Environment', value: depServer), string(name: 'Branch', value: 'master')], 
quietPeriod: 1
}
}
}

}

管道-子

pipeline{
agent any
parameters {
string defaultValue: '', description: 'K', name: 'depServer'
}
options {
buildDiscarder logRotator(artifactDaysToKeepStr: '', artifactNumToKeepStr: '', daysToKeepStr: '', numToKeepStr: '5')
}
stages {
stage('CodePull') {
steps {
echo "Testing"
echo "${depServer}"
}
}
}

}

当我运行父管道时，它并没有触发子管道，但给出了错误。

groovy.lang.MissingPropertyException: No such property: depServer for class: groovy.lang.Binding

在实现建议的更改并进行一些调整后，父作业会触发子作业，但子日志显示它没有接收到传递的参数。

请帮我理解我在这里做错了什么。感谢你的帮助！！

Answer 1

如果您的子管道具有名为"depServer"的参数：

parameters {
string name: 'depServer', defaultValue: '', description: ''
}

你应该为它提供一个值：

build job: 'simple_child', 
parameters: [string(name: 'depServer', value: 'SOMETHING'] 

最后，你应该解决它：

steps {
echo "Testing"
echo "${params.depServer}"
}

Answer 2

groovy.lang.MissingPropertyException：没有这样的属性：depServerclass：groovy.lang.Binding

这意味着您尚未定义变量depServer。

通过将input步骤的结果分配给变量depServer:来修复它

steps {
script {
def input_env = input id: 'Environment', message: 'Approval', parameters: [choice(choices: ['FRST', 'QA', 'PROD'], description: '', name: 'depServer')], submitter: 'FCMIS-SFTP-LBAAS', submitterParameter: 'user'
build job: 'simple_child', 
parameters: [string(name: 'CommitID', value: 'aa21a592d1039cbce043e5cefea421efeb5446a5'),string(name: 'Environment', value: input_env.depServer), string(name: 'Branch', value: "master")], 
quietPeriod: 1
}
}

我添加了一个script块，以便能够创建和分配变量。

input实际上返回一个HashMap，看起来像这样：

[depServer:QA, user:someUser]

这就是为什么我们必须编写input_env.depServer作为构建作业的参数。

非常感谢zett42和MaratC！因此，最终起作用的代码如下(结合两个答案(：

父脚本：

pipeline{
agent any
options {
buildDiscarder logRotator(artifactDaysToKeepStr: '', artifactNumToKeepStr: '', daysToKeepStr: '', numToKeepStr: '5')
}
stages {
stage('Invoke sample_pipleline') {
steps {
script{
def CommitID
def depServer
def Branch
CommitID = 'e2b6cdf1e8018560b3ba51cbf253de4f33647b5a'
Branch = "master"
userip = input id: 'Environment', message: 'Approval', parameters: [choice(choices: ['FRST', 'QA', 'PROD'], description: '', name: 'input_env')], submitter: 'FCMIS-SFTP-LBAAS', submitterParameter: 'user'
depServer = userip.input_env
echo "${depServer}"
build job: 'simple_child', 
parameters: [string(name: 'CommitID', value: "${CommitID}"),
string(name: 'Environment', value: "${depServer}"), 
string(name: 'Branch', value: "${Branch}")], 
quietPeriod: 1
}
}
}
}
}

子脚本：

pipeline{
agent any
parameters {
string defaultValue: '', description: 'K', name: 'Environment'
}
options {
buildDiscarder logRotator(artifactDaysToKeepStr: '', artifactNumToKeepStr: '', daysToKeepStr: '', numToKeepStr: '5')
}
stages {
stage('CodePull') {
steps {
echo "Testing"
echo "${params.Environment}"
}
}
}
}
