推荐答案

这取决于它有多复杂。在大多数情况下，您只需重新压缩所有内容并将zip文件扩展名重命名为 .jar 。如果有清单文件，请务必先包含清单文件。 JDK还提供了一个用于创建jar文件的命令行工具。

It depends on how complicated it is. In most cases you can just rezip everything and rename the zip file extension to .jar. Be sure to include the manifest file first if there is one. The JDK also provides a command line tool for creating jar files.

如果正在修改的代码已签名，那么使用签名重新创建jar显然是不可能的。

If the code being modified was signed, then recreating the jar with signatures will obviously be impossible.
