Java Maven mojo插件从托管项目加载类
我有一个加载类的自定义插件,例如Java Maven mojo插件从托管项目加载类,java,maven,maven-plugin,Java,Maven,Maven Plugin,我有一个加载类的自定义插件,例如 Class<?> clazz = Class.forName(NAME_OF_CLASS_FROM_HOST_DEPENDENCIES); Class clazz=Class.forName(来自主机依赖项的类的名称); NAME_OF_CLASS_FROM_HOST_DEPENDENCIES-是存在于使用此插件的项目依赖项中的类 在主持项目pom时,我将插件称为: <plugin> <groupId>com.plug
Class<?> clazz = Class.forName(NAME_OF_CLASS_FROM_HOST_DEPENDENCIES);
Class clazz=Class.forName(来自主机依赖项的类的名称);
