Jar Jar Links?is a utility that makes it easy to repackage Java libraries and embed them into your own distribution. This is useful for two reasons:

• You can easily ship a single jar file with no external dependencies.

• You can avoid problems where your library depends on a specific version of a library, which may conflict with the dependencies of another library.

spring中https://github.com/spring-projects/spring-framework/blob/3.2.x/build.gradle构建spring-core包，将asm和cglib包inling到spring-core包中。
