cannot find Chrome binary问题解决办法

新手一枚，最近一直在学习Jenkins+testng+maven测试框架，遇到一个这样问题：

本地IDEA执行测试用例正常，但使用Jenkins时就会报以下错误信息：

而且奇怪的是在使用IE浏览器打开测试用例时正常。

经过Google后发现这样一篇文章：https://stackoverflow.com/questions/41144934/cannot-find-chrome-binary-when-executing-a-selenium-testng-test-in-jenkins-on

然后按照上面方法进行操作：

ChromeOptions options = new ChromeOptions();
options.setBinary("C:\\Users\\123\\AppData\\Local\\Google\\Chrome\\Application\\chrome.exe");
System.setProperty("webdriver.chrome.driver","E:/seleniumsever/chromedriver.exe");
driver = new ChromeDriver();

经过验证还是报同样问题。

考虑到权限问题，于是重装了chrome，目录在

C:\\Program Files (x86)\\Google\\Chrome\\Application\\chrome.exe

然后代码改成如下：

ChromeOptions options = new ChromeOptions();
options.setBinary("C:\\Program Files (x86)\\Google\\Chrome\\Application\\chrome.exe");
System.setProperty("webdriver.chrome.driver","E:/seleniumsever/chromedriver.exe");
driver = new ChromeDriver();

再次在Jenkins上重试，问题解决！！！
