Topcoder - Update Build Scripts To Use TopCoder Cache Client Module

BACKGROUND

Recently, All internal system of Topcoder are using TC Cache which is using JBoss Cache as caching service, but this is outdate and keep causing problems for us in production. We'd like to move ahead with a more mature cache services, like Redis.

For the first step, we'd like to separate out the cache related logic from web_module project (already done), and use it as an independent jar file beside the cache.properties.

SCOPE

For this challenge, we'd like you to achieve to the goal of separating the cache related code in web_module.

Generally, you should do 

• Remove web_module/src/main/com/topcoder/web/common/cache except web_module/src/main/com/topcoder/web/common/cache/admin
• Drop the tc_cache.jar (you can build it from https://github.com/appirio-tech/tc-cache) under web_module/lib/jars/tcs/ directory
• Update all build.xml and build_xxx.xml files under web_module to properly build and deploy with the tc_cache.jar���
  • build_cache.xml need to be run under cache user
  • build_distui.xml need to be run under distui user
  • build_tc.xml and build_forums.xml need to be run under tc user
  • build_tcs.xml need to be run under tcs user
  • build_studio.xml need to be run under studio user
  • build_mm.xml need to be run under mm user
  • For others, you need to use your best way to check and verify if they needs change or not.
• Verify that all the systems is still working properly with the new dependent jar and caching is still working properly.
