Uhm... how do I build the latest JBoss from CVS? Or are there nightly builds of JBoss as well?
I found the answer in an other thread:
* get the JBoss AS sources from CVS
* build it by typing ant in the build directory (you will want to increase your heap size by doing a "set ANT_OPTS=-Xmx512m" before so you don't get an OOME)
Once the build will start, it will fetch the thirdparty directory from the web.
My problem was that I was trying to build it with eclipse, which complained about the missing third party stuff.
A quick one to say I think the tag is: JBoss_4_0_3_SP1
Just in case you want this version and are momentarily confused (like I was).
I should have already said that current Seam CVS is currently working against both JBoss 4 branch and JBoss head.
