Robert, they are two ways to compile a project with a version which is not java 9, let say 8 and a module-info with java 9.
Either, like the Maven compiler plugin, you compile twice the source, once with java 9 and once with java 8 excluding the module-info.java, or you compile once with java 8 excluding the module-info and you then compile only the module-info.java with java 9 (it's what Ceki has used). The later solution is usually faster and avoid subtle bugs like if between java x and java 9, the code of javac changes the way a synthetic class is named (you will have the two versions with the compiler plugin). cheers, Rémi ----- Mail original ----- > De: "Robert Scholte" <rfscho...@apache.org> > À: jigsaw-dev@openjdk.java.net > Envoyé: Samedi 25 Mars 2017 18:56:50 > Objet: Re: Progress report on SLF4J project modularization > On Sat, 25 Mar 2017 15:38:27 +0100, Ceki Gulcu <c...@qos.ch> wrote: > >> Following the recipe at [2], it all seems to work. > > Good to read that the recipe works.
