Jenkins NodeJS-Plugin - jenkins

Question

Hello I try to execute nodejs job in jenkins:
Jenkins integration with Grunt
But I can't connect to registry.npmjs.org/ throw Jenkins.
I set the Proxy in Jenkins in Plugins->Advanced but I get stil this error:

$ /var/lib/jenkins/tools/jenkins.plugins.nodejs.tools.NodeJSInstallation/recent_node_0.11.11_/bin/npm install -g grunt-cli#~0.1.0

npm ERR! syscall: 'connect' }
npm ERR!
npm ERR! If you are behind a proxy, please make sure that the
npm ERR! 'proxy' config is set properly. See: 'npm help config'
What should I do now?

Answer 1

I only have a stopgap solution to this as I couldn't find any information on configuring the plugin to work with a proxy. I created a wrapper around the npm executable which sets the proxy details before calling the underlying npm script. The steps:
Setup the NodeJS Installation, start a job which uses it and get the failure (as above). This should leave a Node installation folder in /tools. I see for you this is "/var/lib/jenkins/tools/jenkins.plugins.nodejs.tools.NodeJSInstallation/recent_node_0.11.11_".
Navigate to the /bin folder at this location.
Rename the npm executable link: "mv npm npm-actual"
Create a new npm file: touch npm
Set the contents as follows:
\#!/bin/sh
/var/lib/jenkins/tools/jenkins.plugins.nodejs.tools.NodeJSInstallation/recent_node_0.11.11_/bin/npm-actual config set proxy "<proxy url with optional credentials>"
/var/lib/jenkins/tools/jenkins.plugins.nodejs.tools.NodeJSInstallation/recent_node_0.11.11_/bin/npm-actual config set https-proxy "<proxy url with optional credentials>"
/var/lib/jenkins/tools/jenkins.plugins.nodejs.tools.NodeJSInstallation/recent_node_0.11.11_/bin/npm-actual "$#"
Be sure that this new npm script is owned by the Jenkins user and that it is marked executable.
Re-run the Jenkins job, it should this time make use of the proxy settings above and be able to download what it needs. These settings mimic those found in ~/.npmrc and more info can be found here:

Hope that helps. If anyone has a better, more correct solution I'd love to hear it as well.

You can set NPM to use a proxy, you may need to sudo
npm config set proxy http://yourproxy.com:80
