Build error: mvn package - No such file or directory

[Saulius]

Hi all,

Sorry for a long time no answer - I could not wait any longer so I
moved to my other tasks. Anyway I am ready to continue migrating to
Ebean further now.

So I need to compile the latest version of Ebean myself. What I need
is a jar file. I've checked out the trunk and tried running: mvn
package, but it fails with error. I should not that I am not a keen
maven user, I'm not even sure if 'package' instruction is what I need.

This is all run on Ubuntu 10.04. Here'is what I get:

saulius@dev:~/src/ebean/trunk$ mvn -e package

looks like maven can't run javac - is it setup properly? path etc? can
you run javac from the terminal
BTW I we are still on jdk1.5 - you can build jdk1.6 but you need to
change your settings.xml - that's described here in some thread as far
as I remember

To build use
mvn clean install
To skip the tests add -DskipTests=true
