Ensure no unnecessary class parsing is performed

Currently there is a step in the SBG which parses all JAR dependencies and collects Java interfaces in them in order to be provided for the js parser. Another step after the js parser parses all JARs too. Those can be unified without much effort. Also, other build time generators perform the same JAR parsing. Combining the generators or at least performing the JAR parsing just once could improve the initial build time.

まず、SBG の JAR parsing、js parser、および JAR を解析するその他の build-time generator を追跡します。それらの parsing path を比較し、作業を共有できる箇所を特定します。完了の条件は、generator が不要な JAR parsing を繰り返さなくなり、初期 build time が改善されることです。
