无头Chrome圈CI-错误：生成 /usr/lib64/jvm/java-1.8.0-openjdk-1.8.0/bin/javaENOENT

Question

我正在尝试在无头chrome的Circle CI中运行测试。我使用的是selenium服务器版本3.8.1和chromedriver版本2.34

protractor_conf.js包括Chrome功能：

var chromeCapabilities = {
   browserName: 'chrome',
   chromeOptions: {  
     args: [
     'headless','--show-fps-counter=false', '--remote-debugging-port=2222', '--disable-gpu'
     ]
   }
}

我的sh脚本包括以下命令webdriver-Manager，然后运行测试：

./node_modules/protractor/bin/webdriver-manager clean
./node_modules/protractor/bin/webdriver-manager update --gecko false --versions.standalone 3.8.1 --versions.chrome 2.34
./node_modules/protractor/bin/webdriver-manager start &

echo "*** Run script for e2e tests"
gulp e2e

我在mcircle.yml添加了这些来安装最新版本的稳定chrome，并推出了无头听localhost：

dependencies:
    post:
     # Install the latest Chrome
      - curl -L -o google-chrome.deb https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb
      - sudo dpkg -i google-chrome.deb
      - sudo sed -i 's|HERE/chrome\"|HERE/chrome\" --disable-setuid-sandbox|g' /opt/google/chrome/google-chrome
      - rm google-chrome.deb
    before_install:
      - google-chrome --headless --remote-debugging-port=2222 --disable-gpu http://localhost &

所以，当我现在运行构建时，测试根本不运行。日志显示：

使用的版本：

• Chrome浏览器版本：谷歌Chrome 63.0.3239.132
• 量角器：v5。2.2
• Chromedriver拉链：2.34
• Selenium单机版：3.8.1
• Circle CI:1.0

我错过了什么？任何帮助都将不胜感激。

解决方案：

circle ci上安装的默认java版本为1.7。我强迫它安装1.8 jdk：

• 去循环ci构建测试命令，并使用： java--version命令检查java版本的安装。那里有v1.7表单。
• 然后，我修改了我的Dockerfile，使用jdk 8，方法是使用：from openjdk： 8，这将覆盖安装的v1.7，并强制使用1.8，从而解决了我的问题。
