类名称：JavaCompiler

JavaCompiler介绍

[英]This class could be the main entry point for GJC when GJC is used as a component in a larger software system. It provides operations to construct a new compiler, and to run a new compiler on a set of source files.

This is NOT part of any supported API. If you write code that depends on this, you do so at your own risk. This code and its internal interfaces are subject to change or deletion without notice.
[中]当GJC被用作更大软件系统中的组件时，该类可能是GJC的主要入口点。它提供了构造新编译器以及在一组源文件上运行新编译器的操作。
这不是任何受支持的API的一部分。如果您编写的代码依赖于此，那么您将自担风险。本代码及其内部接口如有更改或删除，恕不另行通知。
