Properly set defaults for gradle properties

Question

Having the following in build.gradle:

uploadArchives {
    repositories {
        mavenDeployer {
            repository(url: "$repoUrl") {
                authentication(userName: "$repoUser", password: "$repoPassword")
            }
        }
    }
}

how can I make $repoUrl have a default value file://$buildDir/repo?

I tried to put repoUrl=file://$buildDir/repo in gradle.properties, but it doesn't work as I expected, as it seems that $repoUrl is not evaluated recursively.

Answer 1

Looks like it is because repoUrl=file://$buildDir/repo is treated as plain string, without buildDir substitution.

If may try this:

repository(url: repoUrl.replace('$buildDir', "$buildDir")) {

Or something like this:

// run as 'gradle build -PreportUrl=blabla'
def repoUrl = "file://$buildDir/repo"
if (binding.variables.containsKey('repoUrl ')) {
 repoUrl = binding.variables.get('repoUrl ')
}

You cannot reference Gradle properties like project.buildDir from properties files. Properties files are very limited, and in general, I'd recommend to keep all information in Gradle build scripts. You can have any number of build scripts, and include them with apply from: "path/to/script" in other scripts.
