推荐答案

默认情况下，Netbeans将在保存模式下使用其编译模式，如

By default Netbeans is going to use its compile on save mode, as mentioned in this other answer. Everytime you modify and save a file, it automatically tries to compile it (as well as required dependencies if any).

虽然此模式处于活动状态，但是您没有对编译的每个文件控制，也几乎没有对项目编译的控制.您唯一的选择是Run-> Clean& Build会删除任何自动编译的类，再次编译所有内容，然后从您的项目中构建一个JAR.

While this mode is active, you have no per-file control on compilation and very little control over project compilation either. Your only option is Run -> Clean & Build which deletes any auto-compiled class, compiles everything again and builds a JAR out of your project.

这样，要控制单文件的编译，首先需要在项目属性的构建/编译"部分中取消选中保存时编译"选项(右键单击项目"选项卡中的项目，然后单击确定").在属性上).完成后，您将在运行"菜单中获得一个新选项:编译文件(默认情况下与F9关联).当然，这也意味着您现在需要在需要时通过运行"菜单手动启动构建.

As such, to control single-file compilation, you first need to uncheck the Compile on Save option in the Build/Compiling section of your project properties (right click on project in Projects tab, click on Properties). Once done, you get a new option in the Run menu: Compile File (associated to F9 by default). Of course, it also means you will now need to manually launch builds through the Run menu whenever it is necessary.
