Properties Files

Reading Properties Files

1. Get the file with new File("file path").

2. Then call withInputStream (closure) on the File object.

   propertiesFile.withInputStream {
      properties.load(it)
   }

Example

For given test.properties file:

a=1
b=2

Properties properties = new Properties()
File propertiesFile = new File('test.properties')
propertiesFile.withInputStream {
    properties.load(it)
}

// testing...
def runtimeString = 'a'
assert properties."$runtimeString" == '1'
assert properties.b == '2'
