Executing a bash script copy_file.sh
from Jenkins Groovy script and trying to shoot mail depending upon the exit code generated form the bash script.
copy_file.sh
:
#!/bin/bash
$dir_1=/some/path
$dir_2=/some/other/path
if [ ! -d $dir ]; then
echo "Directory $dir does not exist"
exit 1
else
cp $dir_2/file.txt $dir_1
if [ $? -eq 0 ]; then
echo "File copied successfully"
else
echo "File copy failed"
exit 1
fi
fi
Portion of the groovy script
:
stage("Copy file") {
def rc = sh(script: "copy_file.sh", returnStatus: true)
echo "Return value of copy_file.sh: ${rc}"
if (rc != 0)
{
mail body: 'Failed!',
subject: 'File copy failed',
to: "[email protected]"
System.exit(0)
}
else
{
mail body: 'Passed!',
subject: 'File copy successful',
to: "[email protected]"
}
}
Now, irrespective of the exit 1
s in bash script, groovy script is always getting return code 0
in rc
and shooting Passed!
mails!
Any suggestions why I can not receive the exit code from bash script in this Groovy script?
DO I NEED TO USE RETURN CODE INSTEAD OF EXIT CODE?
Your groovy code is OK.
I created a new pipeline job to check your problem, but altered it a bit.
Instead of running your shell script copy_file.sh
I created ~/exit_with_1.sh
script, that only exits with an exit code of 1.
The job has 2 steps:
Creation of ~/exit_with_1.sh
script
Run the script and check the exit code that stored in rc
.
I got 1
as an exit code in this example.
If you think something wrong with your groovy <-> bash
configuration, consider replace your copy_file.sh
content with only exit 1
then try to print the result (before posting the emails).
The jenkins job I created:
node('master') {
stage("Create script with exit code 1"){
// script path
SCRIPT_PATH = "~/exit_with_1.sh"
// create the script
sh "echo '# This script exits with 1' > ${SCRIPT_PATH}"
sh "echo 'exit 1' >> ${SCRIPT_PATH}"
// print it, just in case
sh "cat ${SCRIPT_PATH}"
// grant run permissions
sh "chmod +x ${SCRIPT_PATH}"
}
stage("Copy file") {
// script path
SCRIPT_PATH = "~/exit_with_1.sh"
// invoke script, and save exit code in "rc"
echo 'Running the exit script...'
rc = sh(script: "${SCRIPT_PATH}", returnStatus: true)
// check exit code
sh "echo \"exit code is : ${rc}\""
if (rc != 0)
{
sh "echo 'exit code is NOT zero'"
}
else
{
sh "echo 'exit code is zero'"
}
}
post {
always {
// remove script
sh "rm ${SCRIPT_PATH}"
}
}
}
