Services

The saker.jar.create() task allows specifying service classes that are included in the meta information of the created Java archive. For information about the service configuration files see the Service provider specification.

The Services parameter of the task can be used to specify additional services for the archive:

saker.jar.create(
	Services: {
		example.Service: example.ServiceImplementation
	}
)

The above will result in the resulting archive containing an entry at the path META-INF/services/example.Service with the contents of:

example.ServiceImplementation

You can specify multiple services for the parameter as well:

saker.jar.create(
	Services: {
		example.one.Service: [
			example.one.FirstServiceImplementation,
			example.one.SecondServiceImplementation
		],
		example.two.Service: example.two.ServiceImplementation
	}
)

In which case the service file for example.one.Service will contain both specified implementation class names.

When specifying services via the task parameter, the service class names will be merged with any existing service files that were added to the archive.
