问题背景描述

通过官方提供的 AppiumDriverLocalService 方法，代码启动 appium server

 1 import io.appium.java_client.service.local.AppiumDriverLocalService;
 2 import io.appium.java_client.service.local.AppiumServiceBuilder;
 3 import io.appium.java_client.service.local.flags.GeneralServerFlag;

10 public class AppiumDriverTest {
11 
12     public static void main(String[] args) {
13 
14         AppiumServiceBuilder builder = new AppiumServiceBuilder()
15                 .withArgument(GeneralServerFlag.SESSION_OVERRIDE)
16                 .withIPAddress("127.0.0.1")
17                 .usingAnyFreePort();
18         AppiumDriverLocalService service = AppiumDriverLocalService.buildService(builder);
19         service.start();
20     }
21 }

 

得到以下的报错信息

Exception in thread "main" io.appium.java_client.service.local.AppiumServerHasNotBeenStartedLocallyException: The local appium server has not been started.

问题分析定位

引用的第三方依赖包版本冲突，经查找定位为 com.google.guava 版本太低导致，原版本20.0 中没有 SimpleTimeLimiter create() 方法。

 

问题解决方法

更新guava最新版本后，查看源码create() 方法存在
