Subject Re: Build failed in Hudson: Cayenne-trunk » derby,JDK 1.6 (latest),Ubuntu #186
Date Fri, 22 Jan 2010 15:19:58 GMT
Also I changed derby location to the relative Maven build dirs:

derby.jdbc.url = jdbc:derby:./target/derby/testdb;create=true

So there shouldn't be a need to access/manage /tmp. Now waiting for  
some other projects' stuck builds to die so that the Cayenne-trunk can  
start building on Ubuntu machines.
