Apache Felix Maven-Bundle-Plugin 则使用另一套机制：使用Maven-Bundle-Plugin，在开发时可以没有MANIFEST.MF文件！Maven-Bundle-Plugin在pom.xml中复制了一套MANIFEST.MF的元数据，完全可以通过pom.xml文件中的定义生成出完整的MANIFEST.MF文件。

Logger
org.eclipse.e4.core.services插件中的Logger提供了日志功能
Adapter
An adapter can adapt an object to the specified type, allowing clients to request domain-specific behavior for an object. It integrates IAdaptable and IAdapterManager

//Switching perspectives @Execute public void execute(MApplication app, EPartService partService, EModelService modelService) { MPerspective element = (MPerspective) modelService.find("secondperspective", app); // now switch perspective partService.switchPerspective(element); }
// creating parts dynamically @Execute public void execute(EPartService partService) {

# 实现自己的服务
Usually services have two parts: the interface definition and the implementation. How these two are linked is defined by a context function , an OSGi service or plain context value setting (IEclipseContext). Please note that there can be more than one service implementation for an interface.
