Groovy从文件获取变量。 变量=值

Question

Seems like this question for most of others looks too simple. I need a help with following problem. Has file(p.envs) with set of variables and values like:

VARIABLE=foo
NOW=19 October 2014

How to read this file with Groovy to get an output like:

    new File('p.envs').eachLine { line ->
       println line
       ...
    }
    ...
    println "NOW=$NOW"
    println "$NOW"

Output:

NOW=19 October 2014
19 October 2014

This issue can help someone to inject custom variables to groovy template in Editable Email Notification Plugin in Jenkins. Thanks!

Since you are working with a file that follows the Java properties format you can use ConfigSlurper to parse it:

def config = new ConfigSlurper().parse(new File('p.envs').toURL())

The config object implements Map so you can print the values like this:

config.each { key, value -> println "$key=$value" }
