VadimKirilchuk / property-diff.groovy
Created July 25, 2013 10:46
Outputs difference between two java property files. Using just diff is not enough because properties can have different order, duplicated or commented,
if (this.args.length < 2) { throw new IllegalArgumentException("Please, give path to baseline properties and path to other properties")}
def excludeList = [/log4j\./]
File baseline = this.args[0] as File
File other = this.args[1] as File
Properties baselineProps = new Properties()
baseline.withInputStream { stream -> baselineProps.load(stream) }
