Subject Re: questions ant for building a patch
Date Tue, 31 Jul 2007 06:18:47 GMT

hi.  i had the same problems as bwolen.  i am using:

jdk: 1.5.0_07
ant: 1.7.0
os: mac os x 10.4.10
hadoop: 0.13.1

i used the same fix as bwolen (removed lib/jetty-ext/ant.jar), and other
than some warnings, i got a "BUILD SUCCESSFUL".

fyi.
