Quartz is a full-featured, open source job scheduling service that can be integrated with, or used along side
virtually any Java EE or Java SE application – from the smallest stand-alone application to the largest
e-commerce system. Quartz can be used to create simple or complex schedules for executing tens, hundreds,
or even tens-of-thousands of jobs; jobs whose tasks are defined as standard Java components that are
programmed to fulfill the requirements of your application. The Quartz Scheduler includes many
enterprise-class features, such as JTA transactions and clustering.
Many organization and frameworks are using Quartz, Jboss, Spring, and Luntbuild, Quartz Scheduler is licensed under the Apache License, Version 2.0 http://www.quartz-scheduler.org/overview/license-and-copyright

Pay attention to the effects of ‘?’ and ‘*’ in the day-of-week and day-of-month fields!
After install completed, we can crate new project for nightly build, for a luntbuild project, we need to configure it’s:
VCS adaptors; Builders;’ Schedules
VCS adaptors: specify the repository type, URL, userName and password, and we need to specify it’s modules(e.g. java projects in the repository). with those info, luntbuild can update codes before build.
Builders: we can set one or more builder, builder can be Ant or Maven. we need to specify the command and targets, and build success condition.
Schedules: we can create build schedules in this tab, there is one of the most import field is
‘Trigger type’, it can be manual, simple, cron;
Build Type: specify the build type, weather remove all code and update, or just update;
and also can specify the post-builders, like after builder success, we deploy the server;
we can manually start a builder.
Typically, when you trigger a builder manually, luntbuild will:
1. update codes from repository;
2. build the specified builders in the schedule;
3. run the post builders;
4. notify related users by Email, Jabber, Post, etc.( you can specify the properties in Home>Properties)
