我有测试用例（用Java编写）要在设备上运行。应用程序服务器正在运行。现在，按照 https://saucelabs.com/resources/mobile-test-automation-in-java-with-appium 我通过命令运行测试用例 mvn -Dtest=com.saucelabs.appium.SimpleTest test 但是，然后我得到了以下内容：

我不知道我可能错过了什么。
我的系统上的网络限制（端口、防火墙等）问题。我在朋友的系统上尝试了一下，它奏效了。
我不完全同意这一点。 sun.security.provider.certpath.SunCertPathBuilderException建议你无法使用信任存储证书（在java中）构建链。因此，发生这种情况的原因如下：https://repo.maven.apache.org/maven2 证书可能未被有效的 CA 唱歌，或者您必须使用过信任库文件。（不相似）或者您的代理阻止了 OSCP 响应？
