macos - Automatically compile any Java class when the file is dropped in a directory

Question

I look at a lot of small Java programs. It would be convenient if I could set up a directory (or directory structure) on my Mac where any time I add a .java file, javac automatically runs and attempts to compile that file. I've briefly looked into Automator actions, but found nothing that fits the bill. Then I got to thinking: on my PC, I would use the .Net FileSystemWatcher class and write the code myself. But before I try that on my Mac with Mono, I want to ask the community for other ideas. Any advice is appreciated. Thanks.

Answer 1

如果您在开始时拥有所有可用的 .java 文件，则可以编写一个 shell 脚本以一次运行将它们全部编译——如果需要，可以在不同的目录中。

如果你解释了你为什么想要这个，也许我/我们会更有帮助。

Answer 2

在 JDK6 中，您可以通过编程方式编译，因此您可以编写自己的程序来执行此操作，这可能比在单声道中执行要好一些。

因此，您将拥有一个始终运行的程序，它会查找任何新文件或自上次检查以来已更改的文件，然后编译它们，您可能希望它将信息传递到仪表板窗口是错误，也许还有一些状态信息，所以你知道它正在工作。
