Webdriver Jenkins (remote linux) build fails but runs from my local machine(windows)

Question

I've currently been using webdriver from my local machine and now trying to run my tests on a remote machine using Jenkins. When I create my build it fails consistently. When my tests run the following error is displayed [ERROR] Failed to execute goal org.apache.maven.plugins:maven-surefire-plugin:2.19.1:test When I edit my pom.xml file and change it from 2.48 to 2.44 I see a browser error instead. I'm confused what changes I should make. pom.xml file

请检查您在Jenkins上的JVM配置，似乎您运行的是旧版本，是否可以在需要Java 7或更高版本的jenkins上升级JVM / JDK。
