pf4j 默认插件打包模式
pf4j 进行插件打包方法不少，比如fat jar 的，zip 文件的，以及文件夹的
扩展支持的模式
- jar 模式（官方推荐的模式，对于依赖可以基于shared插件解决，注意对于契约服务scope 使用provide模式，不然插件运行会有问题，目前版本测试）
参考配置(shade 插件)
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-shade-plugin</artifactId>
<version>2.3</version>
<executions>
<execution>
<phase>package</phase>
<goals>
<goal>shade</goal>
</goals>
</execution>
</executions>
</plugin>
- 使用zip 文件
zip 文件的约定，包含了classes以及lib 目录，classes是编译之后的class 文件，lib 是三方依赖
参考maven 构建(可以基于maven 的assembly 插件),注意此中模式需要一个plugin.properties 文件
主要提供元数据信息，当然也可以直接在classes 目录提供 MANIFEST.MF 但是不推荐，容易造成
问题

说明
对于plugins 目录我们也可以配置开启以及禁用那些扩展，具体参考官方资料，主要是enabled.txt 以及disabled.txt文件
参考插件目录
plugins
├── loginpluginb-1.0-SNAPSHOT.jar
├── loginpluginc-1.0-SNAPSHOT.jar
└── loginplugind-1.0-SNAPSHOT.zip
对于zip 文件pf4j 为了处理方便先进行解压，然后在进行加载，源码可以参考github 链接
