I don't build the entire jdk source from an IDE, if anyone does I'd be
surprised and would like
to know how that went. There are multiple issues here. And I'm not
against IDEs at all, I love them.
I'm more of a NetBeans user, so I can't say for sure that Eclipse is
any better or worse at the issues below.
Years ago, we heard this request that we had to be able to build the
entire jdk from NetBeans,
but the jdk is not a pure Java project and it is not a pure C/C++
project, and NetBeans seemed to
have this concept that a project was purely Java or purely C/C++, or
did at the time.
Well the only way we could make it work was to have NetBeans build it
from the Makefile, and
it could take anywhere from 45min to 2hours to build the jdk, so why
involve an IDE that will
take more memory and cpu from the machine doing the build? Just use
the command line.
(Now if NetBeans could run locally but do the build on a really fast
remote machine, that would be
more interesting).
So the general feeling was, build it from the command line, then use
NetBeans to edit sources and
do incremental builds. But then we ran into the scale issues, at least
with NetBeans, it wants to scan every
source file in the project, and that just took too long. The entire
jdk project is just too big.
So people started creating smaller NetBeans projects, and only
including the sources for particular areas
of interest. So if you scan the repositories for "nbproject/"
directories you will see the existing NetBeans
projects created by various teams.
As to whether having all these nbproject directories scattered all
over the repositories is a good idea,
well, that's a different topic. NetBeans basically works off of ant
scripts, yours, or ones it creates, which
has it's advantages and disadvantages.
The langtools team and repository use the NetBeans project very
successfully, but langtools is pure java,
and this project only builds langtools (javac, javah, javadoc, ...).
There may also be some Visual Studio project definitions in the
hotspot repository which build hotspot.
Hope this helps in some way.
