Answer by blacktide for How to set project.version by passing version property on gradle command line?

I've found this to be the easiest and cleanest way, without requiring a gradle.properties file or changing the version variable name.

In build.gradle:

// Note - there is intentionally no equals sign hereversion project.hasProperty('version') ? version : '1.0.0'

From the command line:

./gradlew -Pversion=1.5.2 build
