Re: Scanning for projects... hangs

[Ron Wheeler]

We could build most of our projects with the default settings but a 1 or 
2 of our builds would fail until we increased the memory limit.
It is a safe thing to do and does not really cost anything. We are using 
a 1GB size and are not having any more problems.

A GC overhead limit is not an out of memory.
Refer to

for more information about it.
As a work around you can try increasing Xmx as well but that's only
masking the underlying problem and may have no effect.
I seem to remember getting a lot of these with a previous snapshot
version of maven 3 as well and upgrading fixed it.
Why don't you try again with maven 3.0.1 which was released a few wks
ago and see if that fixes it for you.

Hi Everyone,

Its Monday. I would like some help figuring out an issue with my build.
No
only on particular job causes a hang after Scanning for projects...
This issue just popped up after adding some new modules to my parent
pom.xml, I have attached the output, of the build with the -X command
tacked
on. It says that I am running out of memory which isn't the case. Any
suggestions are appreciated.
