I have the following sh
step to execute some commands on Jenkins Pipeline, note the npm install
installs bower from package.json
for later commands to work
sh """
. .env/bin/activate
. ${JENKINS_HOME}/nvm_init.sh
npm install
node --version
which node
echo $PATH
export PATH=\$(npm bin):$PATH
echo $PATH
which bower
which node
node --version
bower install
"""
The output starting from npm install
as below:
+ npm install

npm WARN [email protected] No license field.

ERROR: script returned exit code 1
Here is a couple of things I don't understand:
- Notice the second
echo $PATH
, it has the same path as previously and didn't contain the previous prepend fromexport PATH=\$(npm bin):$PATH
- The last
which node
didn't work, why?
Thanks to colleague @john-carter pointing out that without escaping the the dollar sign, groovy will evaluate before executing the script.
