Question

我想更新jenkins selenium插件（最新版本：2.53.1）。我可以在jenkins之外配置selenium hub和节点，并使用最新的浏览器版本（firefox 51.0.1，chrome 55.0.2883.87）成功运行我的自动化测试，但我只想使用jenkins作为集线器。

这就是为什么我要尝试将最新版本的 selenium-server-standalone（3.0.1）集成到Jenkins中，但它无效。

收到此错误消息：

代码：https://github.com/jenkinsci/selenium-plugin

操作系统：Ubuntu 16.04.2; Eclipse Neon Java IDE，openjdk版本“1.8.0_121”

我已经尝试过使用openjdk 1.7，但它仍然没有用。

我是一个很新手，所以我感谢任何帮助。非常感谢。

根本原因很简单：Jenkins插件的父pom默认强制执行JDK7。 Selenium库已经转向使用JDK8。这解释了执行器插件产生的错误消息。

以下是parent pom

中如何配置enforcer插件的方法

<java.level>7</java.level>

<enforceBytecodeVersion>
  <maxJdkVersion>1.${java.level}</maxJdkVersion>
  <ignoredScopes>
    <ignoredScope>test</ignoredScope>
  </ignoredScopes>
  <excludes>
    <!-- Makes no sense to check core itself: -->
    <exclude>org.jenkins-ci.main:jenkins-core</exclude>
    <exclude>org.jenkins-ci.main:cli</exclude>
    <exclude>org.jenkins-ci.main:jenkins-test-harness</exclude>
    <!--  findbugs dep managed to provided and optional so is not shipped and missing annotations ok -->
    <exclude>com.google.code.findbugs:annotations</exclude>
  </excludes>
</enforceBytecodeVersion>

要解决这个问题，你有两个选择[我从来没有尝试过这个，但它可以尝试看看它是否有帮助]（这两个选项我建议根据你父pom本身的建议）

在构建代码时尝试传递JVM参数-Djava.level=8。
在pom文件中添加如下所示的条目（这将导致enforcer插件可能只忽略selenium库）

Maven的实施者 - 插件显示信息 org.seleniumhq.selenium：硒-java的：：罐：编译 org.seleniumhq.selenium：硒 - 服务器：的：罐：编译

希望有所帮助！

<强>更新我花了更多的时间来看这个，并意识到为这个插件转移到selenium 3.0.1并不是很直接。我已尝试进行更改并为此提出了pull request。您可以查看PR，看看是否有帮助。

PS：我还有3次测试失败。我还没弄明白如何让它们通过。但公关应该帮助你开始。你可以直接结账我的分行并尝试从那里开始建设。

将jenkins selenium插件更新到3.0.1版
