This plugin makes it easy, nay, trivial, to generate and distribute license keys using the open-source license3j library.

There are two plugins in this package:

• org.anarres.license3j.keys - key generation only
• org.anarres.license3j - key generation AND license generation

You must use the org.anarres.mirrors.license3j fork in order to have consistent datetime handling. This plugin generates licenses in the format for that fork, not the mainstream.

This creates a task generateLicenseKeys, which will generate a public-private key pair in build/license3j. No configuration is required but much is offered.

You should copy the generated keys to a location in your source tree (or elsewhere) and preserve them, so that you can check them in the normal license3j manner.

This applies org.anarres.license3j.keys and additionally creates a task generateLicense.

buildscript {
	repositories {
		mavenCentral()
	}
	dependencies {
		classpath 'org.anarres.gradle:gradle-license3j-plugin:1.0.2'
	}
}

apply plugin: 'org.anarres.license3j'

repositories {
	mavenCentral()
}

dependencies {
	implementation 'org.anarres.mirrors.license3j:license3j:3.1.0.2'
}

generateLicense {
	publicKeyFile rootProject.file('src/license/public.key')
	privateKeyFile rootProject.file('src/license/private.key')

	feature "customerName", project.name;
	feature "my-other-feature", "anything"
	issuedAt java.time.Instant.now()
	expiresAfterNow 30, 'DAYS'
}

This will create a license.dat as a resource in your built JAR, which may be loaded using license3j.
