[GitHub] [incubator-dubbo-ops] daiqun opened issue #252: dubbo-admin-backend 2.7.0-SNAPSHOT 启动报错

#### 启动错误如下图所示

#### 根本原因：com.google.guava 包版本不兼容，当前系统中为24.0-jre版本，亲测换为27.0.1-jre有效

抱歉，找错版本了，从打印信息来看应该是com.google.guava:guava:jar:16.0.1

24.0-jre的guava是哪里依赖进来的？ops本身并不依赖这个版本

只是版本对不上的问题，第一张图中append方法在24.0-jre中不存在

请看第一张截图，这份代码是从dev分支上直接download下来的，并没有修改代码，启动直接报错。

报错的是 `ApiListingScanner.java`类中第117行，guava包中的FluentIterable类调用append方法导致的报错，ApiListingScanner在springfox-spring-web-2.9.2.jar中被用到。在dubbo-admin中配置的springfox-swagger2中用到了springfox-spring-web-2.9.2依赖，请看下图
