+1 on Java 8 requirement for Maven runtime (note this still lets you compile with Java 7 if you are prepared to use toolchains... the complexity of using toolchains is an argument for improving/revisiting toolchains)
+1 on getting the place for filtering the pom.xml to produce the consumer pom.xml, but I would go one step further. Enable it by default, but allow opt-out. Also I would suggest to pick up a feature-flagging technique to allow a project to opt out just by declaring the `maven.experimental.___` property in the `pom.xml`. We should be clear that such flags will stop working once the feature is confirmed solid, but NOBODY will turn the experimental flag on, especially if it is a system property only flag... and if we do not have confidence that the feature will work with both the shade plugin and the gpg plugin then - quite frankly - the feature is not ready On Tue, 1 Oct 2019 at 18:31, Robert Scholte <rfscho...@apache.org> wrote: > https://github.com/apache/maven/pull/286 > > On Tue, 01 Oct 2019 13:49:25 +0200, Enrico Olivelli <eolive...@gmail.com> > > wrote: > > > Robert, > > Can you create a PR? > > > > Enrico > > > > Il mar 1 ott 2019, 07:19 Sylwester Lachiewicz <slachiew...@gmail.com> ha > > scritto: > > > >> +1 for Java 8 - let's kill 7 faster ;-)) > >> > >> Sylwester > >> > >> wt., 1 paź 2019, 02:41 użytkownik Olivier Lamy <ol...@apache.org> > >> napisał: > >> > >> > +1 for Java 8 > >> > it's time now and we will probably having more contributions as > >> young/cool > >> > kids prefer using modern tools > >> > Yup the world is not only made with Old Grumpy grand dad working only > >> with > >> > Java 5 :P ) > >> > > >> > On Tue, 1 Oct 2019 at 04:14, Robert Scholte <rfscho...@apache.org> > >> wrote: > >> > > >> > > The versions upgrades of plugins are part of another topic, which > >> are > >> > > indeed 3.7.0 candidates. > >> > > > >> > > As said, the Java 8 update is not just about internal code > >> improvements > >> > > or > >> > > changes.
