v1.8.0

This release introduces the capability to distinguish the plugin API and implementation. The distinction can be made using two jar tasks or source sets. The following example shows a glance of what this new capability is about:

// Remove `api` packages from implementation JAR
tasks.named('jar', Jar) {
    exclude('**\/api\/**')
}

// Configure Gradle plugin API as a custom JAR that only include `api` packages
gradlePlugin {
    api {
        jarTask = tasks.register('apiJar', Jar) {
            from(sourceSet.flatMap { it.output.elements })
            include('**\/api\/**')
            archiveClassifier = 'api'
        }
    }
}

Note this feature may receive breaking changes over the next few releases. Feel free to give it a try and report any issue you encounter.
