Hi,
I'd like to discuss enhacements to the Annotation Processing API for
modules. My current sketch is here (against jigsaw/jake):
http://cr.openjdk.java.net/~jlahoda/8072988/webrev.00/
This patch augments Filer methods with variants that take a "module"
parameter, allowing to generate classes/resources to a particular module
when javac is compiling multiple modules. The existing variants of the
methods try to infer the target module from the given package and
originating elements (see JavacFiler.checkOrInferModule).
This patch should also include module-infos in
RoundEnvironment.getRootElements.
This patch does not allow creating new module-infos. My question is if
that should be supported, and how that should work. There are several
possible scenarios which we could possibly support:
-creating the module-info while compiling for the unnamed module,
converting the compilation to a module (single-module) compilation
-creating the module-info while in multi-module mode (possibly compiling
multiple modules at once), for a directory that exists on the
modulesourcepath, possibly containing some source files, but no
module-info.java. The tricky part is how to work with the sources until
the module-info.java.
-creating whole modules from scratch in multi-module mode (i.e. no part
of the module would exist, and would be completely created by the
annotation processor). Could be tricky with incremental compilation.
Any comments on these or on the patch above would be wholeheartedly welcome.
Thanks,
Jan
