Selenium 3.7.1 gson依赖项抛出ClassNotFoundException

Question

OS：
Windows 10

Selenium版本： 3.7.1（JAVA）

浏览器：
Chrome 62.0.3（64位） Chrome驱动程序2.33.0

升级到Selenium 3.7.1和chrome驱动程序2.33.0之后，由于gson jar上的Class not found异常，我的测试失败了。我可以在maven依赖项中看到jar。我可以通过添加gson作为外部jar来从我的eclipse环境中解决这个问题，但这限制了我只能从IDE运行。

有没有其他人看过这个问题，或者有人能看到我出错的地方？由于gson被列为硒的依赖，我认为我不应该将依赖性添加到我的pom中。任何帮助都会很棒，提前谢谢

Answer 1

从POM.xml中删除以下内容

  <!--Chrome Driver for Maven -->
    <dependency>
        <groupId>org.seleniumhq.selenium</groupId>
        <artifactId>selenium-chrome-driver</artifactId>
        <version>2.33.0</version>
    </dependency>

    <!--IE Edge Driver for Maven -->
    <!-- <dependency> <groupId>org.seleniumhq.selenium</groupId> <artifactId>selenium-edge-driver</artifactId> 
        <version>2.53.0</version> <scope>test</scope> </dependency> -->
    <dependency>
        <groupId>org.seleniumhq.selenium</groupId>
        <artifactId>selenium-edge-driver</artifactId>
        <version>2.47.1</version>
    </dependency>

    <!-- IE Driver for Maven -->
    <dependency>
        <groupId>org.seleniumhq.selenium</groupId>
        <artifactId>selenium-ie-driver</artifactId>
        <version>2.53.1</version>
    </dependency>

这些驱动程序是selenium-java的传递依赖项，因此Maven会自动解决这些驱动程序，并且无需在pom.xml中声明它们。
如果在POM.XML中声明它们，则会导致这些库的版本冲突。 Mavens选择在POM中声明的版本并忽略了nevest版本。

如果你正在使用eclipse，你可以在dependency hierarch tab上观察到它，它看起来像这样
