You need to enable the option
您需要启用该选项
Project Properties -> Build -> Packaging -> Build JAR after compiling
Project Properties -> Build -> Packaging -> Build JAR after compiling
(but this is enabled by default)
（但这是默认启用的）

Do you mean compileit to JAR? NetBeans does that automatically, just do "clean and build" and look in the "dist" subdirectory of your project. There will be the JAR with "lib" folder containing the required libraries. These JAR + lib are enough to run the application.
你的意思是编译成JAR？NetBeans 会自动执行此操作，只需执行“clean and build”并查看项目的“dist”子目录即可。将有包含所需库的带有“lib”文件夹的 JAR。这些 JAR + lib 足以运行应用程序。
If you disable "Compile on save" in the project properties, then it is no longer necessary to do "clean and build", simply "build" will suffice in most cases. This will save time if you want to change just a bit of the code and rebuild the JAR. However, note that NetBeans sometimes fails to handle dependencies and binary compatibility properly, which will lead to a faulty JAR throwing "no such method" or other obscure exceptions. Therefore, if you made a lot of changes since the last full rebuild and even remotely unsure that it will still work even if some classes aren't recompiled, then you must still do a full "clean and build" in order to get a perfectly working JAR.
如果您在项目属性中禁用“保存时编译”，则不再需要执行“清理和构建”，在大多数情况下只需“构建”就足够了。如果您只想更改一点代码并重新构建 JAR，这将节省时间。但是，请注意，NetBeans 有时无法正确处理依赖项和二进制兼容性，这将导致错误的 JAR 抛出“无此类方法”或其他模糊的异常。因此，如果您自上次完全重建以来做了很多更改，甚至不确定即使某些类没有重新编译它仍然可以工作，那么您仍然必须进行完全“清理和构建”以获得完美的工作 JAR。

It does this by default, you just need to look into the project's /distfolder.
它默认执行此操作，您只需要查看项目的/dist文件夹。
