You need to be careful when doing this. If the jars you are merging have manifest files with critical information - these can get lost, only the last file will get merged.
执行此操作时需要小心。如果您正在合并的 jars 包含带有关键信息的清单文件 - 这些文件可能会丢失，只有最后一个文件会被合并。
E.g. If you merge JavaMail - the manifest file is important. If you lose it - bad things csn happen.
例如，如果您合并 JavaMail - 清单文件很重要。如果你失去了它 - csn 会发生不好的事情。
The safest thing to do is to look at each jar file and check the manifest file.
最安全的做法是查看每个 jar 文件并检查清单文件。
