我使用的https://github.com/halo-sigs/plugin-unsplash 这个项目 以haloServer的方式在 gradle中启动 然后把当前halo v2.0.0 分支代码编译完成的产物放到 项目的 workspace下面和 lib下面

halo-2.0.0-SNAPSHOT.jar halo-2.0.0-SNAPSHOT-plain.jar

启动插件项目就出现了这个情况

如果想要以开发模式启动插件只需要做如下配置：

halo:
  plugin:
    runtime-mode: development # 此为开发模式
    plugins-root: ${halo.work-dir}/plugins
    fixed-plugin-path:
      # 替换为 plugin-unsplash 项目路径
      - /path/to/plugin/plugin-unsplash

然后 gradle build 一下 plugin-unsplash 在启动 halo 即可
