Java compilation automation for operation and maintenance automation

"Requirements description"
in order for code to develop, it is necessary to automate the code compilation and deployment process by improving the efficiency of testing and deployment on-line.
here's how to use Javac Automation to compile Java code.
because the project is currently not using Ant, Maven and other management constructs, so need to use the comparison of the original javac to achieve, very hurt wood.

"Background notes"
Code directory Structure
1. Web type code: Reach the War package (on one directory), deploy with Tomcat

Introduction to the project directory structure for Web types
# Ls/home/souces/boss-web
src webcontent
src store Java source code: Java files, properties files, XML files, etc.
WebContent Store Html,js,css and other documents
 
2, service type of code, will eventually be hit as a jar package deployment

The Lib directory holds the jar packages that the Java project relies on
src store Java source code: Java files, properties files, XML files, etc.

PS: Well, this is a relatively primitive project structure, the latter to promote the development of the use of MAVEN, although not maven, but as an operation, to see recruit demolition Ah, so also in the current situation to give the program drops.

3, compile directory structure comb
/home/build/Store Compilation script: Build.sh
/home/sources/Storing source code
/home/target/to store compiled "directories"
/home/tgzs/Store tgz package after compiling and compressing.
After each release of the tgz integration of Tgz and config using code, you can publish the
test-web.20140826234520.p_3547.tgz
config_2.20140826234520.cfg_3544.tgz
In fact, I omitted the code, the configuration file svn management, and update the source code of/home/sources/script, the script will be implemented.
