Yes. But. The current content breaks the expected semantics of the
ServiceLoader mechanism.
That is, a line in a file such as META-INF/services/com.acme.Foo, is
expected to be
- a fully classified classname
- with no-args constructor
- that implements (if the filename denotes an interface) or extends (if
the filename denotes a class) the target type.
Per these rules the content of
META-INF/services/org.codehaus.groovy.source.Extensions
is wrong.
Given that this metadata file is to be used by the Groovy compiler alone it
would be better to use a different path/naming convention that does not
clash with existing Java conventions, something like
META-INF/groovy/org.codehaus.groovy.source.Extensions
Unless I missed something this should work, shouldn't it?
Cheers,
Andres
