我正在尝试按照以下方式在 Jenkinsfile 中设置环境变量,
pipeline {
agent { label 'slave1' }
stages {
stage ('Build') {
steps {
script {
BUILD_VERSION = sh (
script: 'python get_firmware_version.py',
returnStdout: true
).trim()
}
echo "${BUILD_VERSION}"
withCredentials([file(credentialsId: 'image-sign', variable: 'IMAGE_SIGN')]) {
dir('firmware/') {
echo "${BUILD_VERSION}"
sh '''
echo "Building"
echo "${BUILD_VERSION}"
echo "${env.BUILD_VERSION}"
'''
}
}
}
}
}
post {
failure {
script {
echo "Pipeline Failed"
}
}
}
}
但它失败并出现以下错误
Bad substitution
[Pipeline] echo
0_2_0
[Pipeline] sh
+ echo Building
Building
/home/jenkins/jenkins_slave/workspace/Firmware/Branch/firmware@tmp/durable-54e04481/script.sh: 3: /home/jenkins/jenkins_slave/workspace/Firmware/Branch/firmware@tmp/durable-54e04481/script.sh: Bad substitution
为什么我不能设置 ENV Var 并在 sh 步骤中使用它?
最佳答案
我认为这是 Jenkins 的事情。当您使用 sh
用 '
阻止;它将无法访问诸如环境变量之类的东西。尝试使用 "
反而。那应该工作
sh """
echo "Building"
echo "${env.BUILD_VERSION}"
echo "${env}"
"""
Jenkins 应该识别 shell 块并逃脱
"
内"""
自动地。pipeline {
agent { label 'slave1' }
stages {
stage ('Build') {
steps {
script {
BUILD_VERSION = sh (
script: 'python get_firmware_version.py',
returnStdout: true
).trim()
}
echo "${BUILD_VERSION}"
withCredentials([file(credentialsId: 'image-sign', variable: 'IMAGE_SIGN')]) {
dir('firmware/') {
echo "${BUILD_VERSION}"
sh """
echo "Building"
echo "${BUILD_VERSION}"
echo "${env.BUILD_VERSION}"
"""
}
}
}
}
}
post {
failure {
script {
echo "Pipeline Failed"
}
}
}
}
My test case
pipeline {
agent {
node {
label 'devops-jenkins-slave'
}
}
options {
timestamps()
}
stages {
stage('Setup'){
steps {
dir("${WORKSPACE}/"){
script {
BUILD_VERSION = "1"
}
sh """
echo "${BUILD_VERSION}"
"""
}
}
}
}
post {
always {
dir("${WORKSPACE}/"){
deleteDir()
}
}
}
}
Result

关于jenkinsfile 没有将 env 传递给 sh,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/55071024/
