+     *      2) 拉取 git 仓库至临时目录
+     *      3) 构建、并移动至 $PARTNER_HOME/resource/partner-core.jar
+     * 3. gateway 配置 -> $PARTNER_HOME/config/gateway.json:
+     *    - WebSocket Gateway
+     *    - OneBot Gateway
+     * 4. 模型配置 -> $PARTNER_HOME/config/model.json:
+     *    - 提供商1
+     *    - 提供商2
+     * 5. 结束
