Tango SPI is a Gradle plugin that is designed to automatically generate the provider-configuration file necessary for using the java.util.ServiceLoader functionality.
For a general introduction to the Service Provider Interface (SPI) see this Java tutorial, but at a high level this allows you to create a plugin system where you can add/remove plugins by adding jars to the classpath and not introducing a compile-time dependency.
- This plugin only supports Gradle versions >= 3.0 (and by extension Java 7)
- This plugin requires the Java Plugin to be applied to your project
- Import the plugin to gradle
plugins {
id "net.sjrx.tangospi" version "0.1"
}- Configure the interfaces that you would like to auto generate:
tangospi {
interfaces = ['example.foo.interfaceName']
}- Compile, and the necessary files should be generated.
Not supported at this time (probably have to manually apply the task, but I haven't tested that yet)

Previously the author used the unmantained Mango SDK package however because it uses annotation processing, it does not work with non Java languages like Scala. Additionally the annotation used has a Source.RetentionPolicy and so it could not be used.

Searching google found a Maven plugin META-INFO/services auto-generation, obviously however this is for Maven.
