In gradle is it possible to include a different jar based on a flag

Question

If I have a simple gradle java build, can I somehow swap out one of the jar dependencies, say jarX for jarY based on a flag?

e.g.:

if running ./gradlew build - then include jarX

but if running ./gradlew build -specialBuild - then include jarY instead of jarX

Yes, you can use conditional statements on the dependencies {} closure.

dependencies {
    if (project.hasProperty("useX")) {
        implementation 'x:x:x'
    } else {
        implementation 'y:y:y'
    }
}

call as

gradle -PuseX=true
