> With color support, core Maven and plugins do general message colorization
> (or more high-level "message styling" through maven-shared-utils)
> slf4j provider however has to add color:
> - for log level output (DEBUG/INFO/WARNING/ERROR)
> - for stacktrace rendering
> That's why we use Gossip slf4j provider: it has sufficient little extension
> points to add this, with just a little bit of code (see
> http://maven.apache.org/ref/3-LATEST/maven-embedder/apidocs/org/apache/maven/cli/logging/impl/gossip/package-summary.html
> ) and configuration
> The issue with switching to Gossip slf4j provider is that people don't know
> it and it does not have the same features as slf4j-simple (missing relative
> timestamps and configuration with CLI: see
> http://mail-archives.apache.org/mod_mbox/maven-dev/201607.mbox/%3CCAK8jvqxYNK4weM2Frp4Brg3J7EybyjBiCsSRdGuNMQhYAG728Q%40mail.gmail.com%3E
> ), the configuration file is not the same (name nor content).
> But the extension points are not that big: if slf4j-simple provider just made
> a few methods protected instread of private, it would be extensible
> What if we just copy slf4j-simple to change the signatures and create small
> extension classes? The license permits it, we can try it and eventually see
> with slf4j if the modification can go into official release
