[kapua-dev] Activating Maven toolchains in build

[Jens Reimann <jreimann@xxxxxxxxxx>]

Hi,

I did find yesterday that the web console project, which only supports Java 7 dues to the old GWT version, actually used Java 8 APIs.

This shouldn't be a big deal, since it will probably still be used on Java 8.

However as we are slowly nearing Java 9 and at some point we may run into mixed environments of Java 8 and 9, I would suggest that we make use of the Maven toolchains feature and actively validate against proper JDK levels.

I made a PoC for this in [1], which activates toolchains for the console project and provides toolchain files for RHEL/CentOS/Fedora and Travis CI.

If there are no objections, I would like to merge this.

Cheers

Jens
