I need to increase the sleep time in the java class FSMasterDirectoryProvider.java which is in hibernate-search-engine-4.5.3.Final.jar. I tried getting the sources jar for the same version and recompile and package it by modifying the sleep time. I used jdk1.7 while recompilation and packaging. But when I deployed that jar, I started getting different type of exceptions. Is there any other way to get the source and modify it? and where can I get all the dependency list which will be require for building and packaging.
