Question

最近我们升级到最新的selenium版本3.4.0。虽然在POM更新后一切正常，但经过一些成功的构建后，构建错误开始出现，而我们的代码或POM没有任何明显的变化。

以下是我的POM的样子：

当我进行全新安装时，这是它在控制台中抛出的内容：

当我通过jenkins运行它时会发生同样的问题。我尝试过以下操作：

删除.m2存储库并重建
在eclipse中重新导出后重新构建项目（虽然问题不在于eclipse）
构建时强制更新
对项目进行了maven更新

没有用！

Answer 1

我认为在你的pom artifactId selenium-api 它应该是 selenium-java 。请参阅以下内容：

<!-- https://mvnrepository.com/artifact/org.seleniumhq.selenium/selenium-java -->
    <dependency>
        <groupId>org.seleniumhq.selenium</groupId>
        <artifactId>selenium-java</artifactId>
        <version>3.4.0</version>
    </dependency>

Answer 2

以下是您的问题的答案：

错误说明了一切：

Failed to collect dependencies at org.seleniumhq.selenium:selenium-server:jar:3.4.0 -> org.seleniumhq.selenium:selenium-java:jar:3.4.0 ->  org.seleniumhq.selenium:selenium-api:jar:[3.3.1,4.0.0)

当您在selenium-server中使用pom.xml依赖关系时，如下所示：

＆＃13;

    <dependency>
        <groupId>org.seleniumhq.selenium</groupId>
        <artifactId>selenium-server</artifactId>
        <version>3.4.0</version>
    </dependency>

＆＃13;

Selenium Documentation在这里明确提到

如果您的项目将在Web应用程序容器中运行，那么selenium-server工件依赖于 servlet-api-3.1.0 工件，您应该排除该工件。

添加servlet-api-3.1.0 artifact将解决您的问题。

如果这回答你的问题，请告诉我。

升级到最新的selenium版本后，定期生成失败
