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

问题描述

我是通过Eclipse运行使用硒我的UI自动化测试案例，它通过罚款没有问题。浏览器启动，测试用例的执行，当我在Eclipse中做的结果被更新。然而，当我试图通过Ant来运行它，它开始给我的异常，

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

请参阅我的项目的连接结构，


参考我的Ant文件（build.xml文件），

解决方案

的惊喜：Eclipse中，自动明白即使有重复的罐子，并能够运行测试脚本。然而，ANT不能这样做。所以，我删除了罐子com.google.common，这让我从从命令行运行测试脚本。

教训：不要有重复的.jar文件

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.collect.Multimaps.transformValues(Lcom/google/common/collect/ListMultimap;Lcom/google/common/base/Function;)Lcom/google/common/collect/ListMultimap;

See the attached structure of my project,

解决方案

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.

Lesson learnt: Do not have duplicate .jar files.
