將jenkins selenium插件更新到3.0.1版

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集線器和節點，並且使用最新的瀏覽器版本（firefox 51.0.1，chrome 55.0.2883.87）成功運行我的自動化測試，但我只是想用jenkins作爲集線器。

因此，這就是爲什麼我試圖將最新版本的selenium-server-standalone（3.0.1）集成到Jenkins中，但它不起作用。

收到此錯誤信息：

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

操作系統：Ubuntu的16.04.2; Eclipse霓虹Java IDE，openjdk版本「1.8.0_121」

我已經嘗試過openjdk 1.7，但它仍然無法正常工作。

我在這是一個新手，所以我很感激任何幫助。非常感謝。

Answer 1

根本原因很簡單：Jenkins插件的父pom默認強制執行到JDK7。硒庫已經開始使用JDK8。這解釋了執行者插件引起的錯誤消息。

這裏是如何的實施者插件已經在parent pom

<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> 

被配置爲解決這個問題，你有兩個選擇[我從來沒有嘗試過這一點，但它的東西，你可以嘗試看看它是否有幫助]（這兩個選項我建議根據您父母本身的建議本身）

• 嘗試傳遞JVM參數-Djava.level=8當你建立的代碼。

• 添加一個條目，如下面的POM文件（這將導致執法插件或許忽略只有硒庫）

  Maven的實施者 - 插件 顯示信息 組織.seleniumhq.selenium：selenium-java：：jar：compile org.seleniumhq.selenium：selenium-server：：jar：compile
  

希望幫助！

更新 我花了更多的時間看這個，並意識到轉移到硒3.0.1這個插件並不是非常簡單。我已經嘗試做了更改，並提出了相同的pull request。你可以看看公關，看看是否有幫助。 PS：我還有3次測試未能通過公關測試。我還沒有想出如何讓他們通過。但公關應該可以幫助你開始。你可以直接檢查我的分支並嘗試從那裏建設。
