Override a gradle option defined in the master project - gradle

Question

I'm adding an upload archive directory for all subprojects via
uploadArchives {
repositories {
flatDir {dirs '../REPO'}
}
}
Now I need to specify a different directory for one subproject.
I've found out that doing it adds to the list, but I'd like to replace the directory. I know I could use subprojects.findAll, but I'll need the possibility to override a setting elsewhere, too.
Disclaimer: My question may sound stupid, but I'm using gradle since a few weeks and must confess, I know hardly anything about it. I like it and it works fine, but reading the manual is not an option (I'm just a BFU and I'd rather switch to makefile before reading it all).

Often, the cleanest solution is to configure things the right way from the start. There are several ways to do this. For example:
rootProject/build.gradle:
configure(subprojects - project(":foo")) {
uploadArchives {
repositories {
flatDir {dirs '../REPO'}
}
}
}
project(":foo") {
uploadArchives {
repositories {
flatDir {dirs '../OTHER'}
}
}
}
Alternatively, you could have two auxiliary scripts gradle/repoA.gradle and gradle/repoB.gradle, and each subproject build script would apply the appropriate script with apply from: "$rootDir/gradle/repoX.gradle".
Finally, overriding the value might work too (untested):
rootProject/subproject/build.gradle:
uploadArchives.repositories[0].dirs = ["../OTHER"]
