Issue

The Config File Provider Plugin isn’t only for Maven jobs. You can define a custom config file of any type. Here we push a npmrc file to your NodeJS build.

Environment

Resolution

1. Go to Manage Jenkins, then Managed Files and select Add a new Config

2. Select Custom file and click Submit

3. Name the config file npmrc with Content

npm_config_registry=localhost:1234
npm_other_var="some_value"

and click Submit to save

1. After saving you should see
   

2. Create a Pipeline job
   Note: fileId associates with the custom config file you have just created
   Note: variable allows you to retrieve the content as an environment variable

node ('LINUX_GENERAL') {
    stage ('build') {
        configFileProvider([configFile(fileId: 'c9f8086f-0820-49ff-a66d-262bcaac7aac', variable: 'npm_config_registry')]) {
            // some block
            echo " =========== ^^^^^^^^^^^^ Reading config from pipeline script "
            sh "cat ${env.npm_config_registry}"
            echo " =========== ~~~~~~~~~~~~ ============ "
        }
    }
}
