[Webtest] [dev] build re-animated

[Dierk Koenig]

Hi Developers,

we recently had some problems with the continuous build installation. 
Therefore, we transferred the build execution
to a new machine with less load.
No externally visible URL changes.

The build is working again, but we had to temporarily disable
the Applet tests as they do fail with "Connection reset" on
the build machine. 

Build time is still much too long (20 mins) while it runs
in 3 mins on my laptop. Reading through
the xml logs suggests that the delay is distributed evenly
over the tasks. 

I think about introducing a flag to distinguish between a full
and a minor build. Minor builds could compile incrementally and
skip some tasks like clover, checkstyle, apidoc, manuals? and
skip some of the selftests (pdf?, applet?, groovy?).
Full builds on the buildserver could be run on an own schedule
(nightly?, force manually?).
Developers would still be obliged to run the full build locally
before any commit.

Any options on this?

cheers
Mittie
