Description

I have a properties file name "my.properties":

level1.level2.key1   1
level1.level2.key2   2
level1.level2        3

When the following code is run...

def loadProperties(filename) {
    Properties properties = new Properties()
    properties.load(new FileInputStream(filename))
    properties
}

def properties = loadProperties("my.properties")
def config = new ConfigSlurper().parse(properties)

println "properties:     " + properties
println "slurper:        " + slurper
println "property value: " + properties.getProperty("level1.level2.key1")
println "slurper value:  " + slurper.level1.level2.key1

...it prints

properties:     ["level1.level2":"3", "level1.level2.key2":"2", "level1.level2.key1":"1"]
slurper:        ["level1":["level2":"3", "level2.key2":"2", "level2.key1":"1"]]
property value: 1
Caught: groovy.lang.MissingPropertyException: No such property: key1 for class: java.lang.String
        at config_slurper.run(config_slurper.groovy:13)
        at config_slurper.main(config_slurper.groovy)

I would expect to also get "1" for "level1.level2.key1" via the ConfigSlurper (as I get it via Java's Properties). Looks like the internal map representation cannot handle such cases.
