Subject: [PATCH] CAMEL-24318 - improve regen.sh
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* use multithreads for Maven to improve performance. locally with 22
cores, it divided the time by 2. On GitHub CI, it won't be that much as
there is only 4 Cores currently
* remove x option from git clean to avoid removing the files which are
part of .gitignore, for instance all IDE related files
* renamed the build log to avoid overriding the first one and to be able
to keep both of them
