Theodor Tolstoy commented on GROOVY-5194:
-----------------------------------------
Frustrating.
I want to filter my configuration by environment and then save the resulting
configuration to the war file. I had the same problem.
My workaround is to use the prettyPrint() on the ConfigSlurtper when saving the
configuration to file. The object is not as pretty, but it works for my
transforming purpuses.
This is my Gradle method :
def loadConfiguration() {
def environment = hasProperty('env') ? env : 'dev'
project.ext.environment = environment
def configFile = file('configValues.groovy')
def config = new
ConfigSlurper(environment).parse(configFile.toURI().toURL())
config.mode = ext.environment
config.buildTimeStamp = (new Date()).format('yyyy-MM-dd HH:mm:ss')
file('./src/main/resources/config.groovy').text = config.prettyPrint()
}
> ConfigSluper cannot re-parse a file written by itself.

> config file is as below:

> c {
> x1 = "x1"
> x2 {
> y1 = 1

> ConfigSlurper can parse correctly. But when call its writeTo method to a

> one"list.x1"="x1"
> onex2."list.y1"=1
> "list.two"="2000"
> This output file cannot be re-parsed.
> The error message in stdout as below:
