创建new AndroidDriver初始化时候报错:报错java.lang.NoSuchMethodError: com.google.common.base.Throwables.throwIfUnchecked
在手机UI自动化项目开发中,使用appium框架进行开发,发生不少依赖冲突问题。项目使用spring cloud + appium手机UI自动化框架进行开发。appium版本4.1.2。
在appium初始开发中,发现driver = new AndroidDriver(new URL(appiumServerUrl), capabilities); 语句报错,appium对应的driver session已经正常创建,app应用已经启动,但出现此报错无法继续操作。 java.lang.NoSuchMethodError: com.google.common.base.Throwables.throwIfUnchecked(Ljava/lang/Throwable;)V
详细报错日志如下

解决思路
应该是jar依赖的问题,可能发送冲突,或者引入版本不对。查看com.google.common.base.Throwables.throwIfUnchecked 经过错误位置检查发现此类和方法在guava-19.0.jar依赖中,后面经过源码查看,确实该com.google.common.base下的类Throwables无此方法,应该是appium的一个bug。 后面经过修改maven配置排除guava依赖,然后手动更新此jar包依赖到guava-22.0.jar后项目运行正常。
修改如下
<dependency>
<groupId>io.appium
</groupId>
<artifactId>java-client
</artifactId>
<version>4.1.2
</version>
<exclusions>
<exclusion>
<groupId>org.springframework
</groupId>
<artifactId>spring-core
</artifactId>
</exclusion>
<exclusion>
<groupId>com.google.guava
</groupId>
<artifactId>guava
</artifactId>
</exclusion>
</exclusions>
</dependency>
<dependency>
<groupId>com.google.guava
</groupId>
<artifactId>guava
</artifactId>
<version>22.0
</version>
</dependency>
修改配置文件后,项目运行正常。
