[workflow-plugin] Reading and parsing property file

[Rupali]

Hi,

I tried reading file from workspace using readFile and then echo the results. That works just fine. But I was unable to parse it and retrieve specific values. Is there a way to parse the contents of this file and read properties into variables?
File will contain key=value kind of entries.

Regards,
Rupali

Hi Rupali,

readFile returns a String object with the entire contents of the file - 
so you can parse it using stand java/groovy APIs.

.e.g.
you can chain a StringReader and Properties

https://docs.oracle.com/javase/7/docs/api/java/util/Properties.html#load(java.io.Reader)
http://docs.oracle.com/javase/8/docs/api/java/io/StringReader.html#StringReader-java.lang.String-

pseudo code...

    def str = readFile name: 'somefile', charset : 'utf-8'
    def sr = new StringReader(str)
    def props = new Properties()
    props.load(sr)

    def foobar = props.getProperty('somepropname')

Thanks James.
That worked.

FYI - the syntax for readFile() is incorrect. It should be:

        def str = readFile file: 'somefile', encoding : 'utf-8'
