PROSAGA码农传奇-SF服务编织-Eclipse RCP：编织时如何添加内部类

这是一个有效的解决方案，将内部类的类文件复制到包含weave目标的第三方插件的bin /目录中。如果有人知道这样做不太麻烦，请发布单独的答案。

编辑：使原始解决方案更通用，找到要编织的类的所有内部类文件，如果缺少或大小不同，则将它们复制到编织目标插件。

```
public class Activator extends Plugin {

...

public static final String CLASS_FILE_ROOT = "bin/";

/**
 * Binary weaving of a class file may result in the addition or modification of
 * inner class files in this plug-in which need to be placed on the classpath
 * of the plug-in containing the weave target. This method compares inner class
 * files for a given class in this plug-in with inner class files in the plug-in
 * that contains the weave target. Any inner class files missing from the weave
 * target or with a different size than the corresponding file in this plug-in
 * are copied to the appropriate package directory in the weave target plug-in.
 * 
 * @param bundle the bundle of the class being woven
 * @param className the fully qualified name of the class being woven
 * @return true if no errors were encountered in copying the inner class files
