I am new to Jenkins, Groovy and pipelines. I have created a simple pipeline stage like so:
//working build but not setting env variables
node('build-01') {
stage('Building') {
echo "[*] Starting build (id: ${env.BUILD_ID}) on ${env.JENKINS_URL}"
try {
sh 'ls -l'
//ls shows the damn file
sh '. setup-target'
} catch(all) {
sh "echo 'Failed to run setup-target script with error: ' ${all}"
}
}
}
This works. But I want to modify/add environment variables to the session running this script (this script is a bash file with the correct shebang line on top). So I did:
node('build-01') {
withEnv(["CMAKE_INSTALL_DIR=${WORKSPACE}", "SDK_INSTALL_DIR=${WORKSPACE}"]){
stage('Building') {
echo "[*] Starting build (id: ${env.BUILD_ID}) on ${env.JENKINS_URL}"
try {
sh 'ls -l'
//ls shows the damn file
sh '. setup-target'
} catch(all) {
sh "echo 'Failed to run setup-target script with error: ' ${all}"
}
}
}
}
This errors out with:
/home/jenkins-sw/ci/workspace/myWorkSpace@tmp/durable-6d30b48d/script.sh: line 1: .: setup-target: file not found
and
Failed to run setup-target script with error: hudson.AbortException: script returned exit code 1
But the environment variables are set, I check this by doing a sh 'printenv'
right below the ls -l
line. Interestingly ls -l
does show the script.
What am I missing?
The following:
node('build-01') {
withEnv(["CMAKE_INSTALL_DIR=${WORKSPACE}", "SDK_INSTALL_DIR=${WORKSPACE}"]){
stage('Building') {
echo "[*] Starting build (id: ${env.BUILD_ID}) on ${env.JENKINS_URL}"
try {
sh 'ls -l'
//ls shows the damn file
sh './setup-target'
} catch(all) {
sh "echo 'Failed to run setup-target script with error: ' ${all}"
}
}
}
}
results in:
/home/jenkins-sw/ci/workspace/myWorkSpace@tmp/durable-6d30b48d/script.sh: line 1: ./setup-target: Permission denied
Interesting. How is withEnv effecting permissions? What?! And if I chmod that file to have permissions, i get a new error, something related to "missing workspace".
My guess would be that either CMAKE_INSTALL_DIR
or SDK_INSTALL_DIR
are on the path.
Instead of sh '. setup-target'
sh '. setup-target'
you should sh './setup-target'
.
I figured it out. I was cloning directly into the workspace and then setting my environment variables to point to the workspace as well. I modified both those things. I now create a dir in my workspace and clone into it and I also set my environment variables to directories inside my workspace. Like so:
node('build-01') {
withEnv(["CMAKE_INSTALL_DIR=${WORKSPACE}/cmake_install", "SDK_INSTALL_DIR=${WORKSPACE}/sdk"]){
stage('Building') {
echo "[*] Starting build (id: ${env.BUILD_ID}) on ${env.JENKINS_URL}"
try {
sh 'ls -l'
//ls shows the damn file
dir('path/to/checkout/') {
sh '. ./setup-target'
}
} catch(all) {
sh "echo 'Failed to run setup-target script with error: ' ${all}"
}
}
}
}
This works.
