当尝试通过ANT运行时，Selenium webdriver将抛出异常 [英] Selenium webdriver throws exception when trying to run via ANT

问题描述

我使用selenium通过Eclipse运行我的UI自动化测试用例，没有任何问题。浏览器被启动，测试用例被执行，当我在Eclipse中执行结果时会更新结果。而当我试图通过ANT运行它，它开始给我例外，

I am running my UI automation test cases using selenium via Eclipse, it goes through fine with no problem. Browsers are launched, test cases are executed, results are updated when I do it in Eclipse. Whereas, when I tried to run it via ANT, it started giving me exception,

java.lang.NoSuchMethodError：com.google.common。收集.Multimaps.transformValues（Lcom / google / common / collect / ListMultimap; Lcom / google / common / base / Function;）Lcom / google / common / collect / ListMultimap;

推荐答案

惊喜：Eclipse，即使有重复的jar，并且能够运行测试脚本。但是，ANT无法做到这一点。所以我删除了com.google.common的jar，这让我从命令行运行测试脚本。

The surprise: Eclipse, understood automatically even if there are duplicate jars and was able to run the test scripts. However, ANT could not do that. So, I removed the jar com.google.common, which made me to run the test scripts from command line.

经验教训：没有重复的.jar文件。

Lesson learnt: Do not have duplicate .jar files.
