Hi,
the work on speeding up the build resulted in the following pull request, also thanks to
Christian assistance to fix some security tests:
https://github.com/geoserver/geoserver/pull/1033
On my computer the buld times of a “mvn clean install -T4 -nsu -Prelease”
went down from around 18 minutes down to around 13 minutes, not a bad speedup imho,
close to 30%
On Travis, which has to download all the geotools jars at every build,
refresh the repository cache at the beginning of each build, and so on,
we go down from 37 minutes to 30 on the openjdk builds, which is not bad either
(the last build timed 39, not sure why, the enviroment over there is really flacky,
build times go up and down as they please…).
I’ve annotated the pull request with descriptions of the changes to facilitate
life to the reviewer, feedback welcomed.
Also, I’ve found looking on the internet a suggestion to allegedly speed up the build
on windows… turns out the clean phase is pretty expensive on NTFS (blasted
file system) and you can speed it up quite a bit by simply renaming
target instead of deleting it (on Linux, no speedup achieved instead, delete
or rename is similarly fast).
One can apply this trick, and have a separate build to do the cleanups instead:

Might be worth checking out, the current build time on the windows build box
is over an hour long…
Cheers
