如果不升级其依赖项，则无法随机升级单个jar文件：升级所有罐子。

You cannot randomly upgrade single jar files without upgrading their dependencies: upgrade all the jars.

为了将来解决这个问题，（a）看看发行版中发布的罐子，（b）使用Maven或类似的东西并停止手工进行依赖管理 - 这不值得，这很难。

To solve this problem in the future, (a) look at the jars shipped in the distro, (b) use Maven or similar and stop doing dependency management by hand--it's not worth it, and it's difficult.
