我在使用Jenkins进行自动化测试时遇到问题，我从Jenkins控制台获得了如下错误堆栈跟踪信息：

我的Appium版本v1.15.1
当我用eclipse测试我的代码时，它的工作正常。我以为这个错误可能是我重复的称硒。
有人可以帮助我解决这个错误吗？

...表示 AndroidDriver 无法通过 Appium 启动/产生新的浏览上下文。
来自服务器端日志（Appium日志）的更多信息将有助于我们以更好的方式分析问题。但是，根据讨论Error: The instrumentation process cannot be initialized，在appium v1.11 及更高版本中发现了此问题，在版本 v1.10.1 中存在没有这样的问题。大概服务器端日志（Appium日志）将包含与 UiAutomator2 相关的以下日志消息：
[UiAutomator2] 'skipServerInstallation' is set. Attempting to use UIAutomator2 server from the device
[UiAutomator2] Waiting up to 60000ms for UiAutomator2 to be online...
[debug] [ADB] Creating ADB subprocess with args: ["-P",5037,"-s","emulator-5554","shell","am","instrument","-w","io.appium.uiautomator2.server.test/androidx.test.runner.AndroidJUnitRunner"]
[debug] [Instrumentation] android.util.AndroidException: INSTRUMENTATION_FAILED: io.appium.uiautomator2.server.test/androidx.test.runner.AndroidJUnitRunner
P可能的原因是 UiAutomator2 没有安装在设备上，或者可能是服务器安装被明确禁用。
一个简单的解决方案是在Appium内升级/降级 UIAutomator2 ，但是您不能这样做，因为 UIAutomator2 依赖于其他模块。
因此，解决方案是降级整个Appium软件包。另外，您也可以在运行测试的设备上更改模拟器。有时，从设备上卸载Appium Settings应用并重新启动 Appium 进程即可解决此问题。
