homePage（ActiveComponentTest）时间：2.06秒问题在我看来，我的POM中的一个项目依赖项引入了一个不同且不兼容的nekoHTML版本
一旦我删除了令人不快的依赖项（这是im测试项目的延迟，而不是我用来测试另一个项目的本项目——长话短说），一切都很好。@jlars62，您的pom中可能有类似的内容：
<dependency>
<groupId>net.sourceforge.htmlunit</groupId>
<artifactId>htmlunit</artifactId>
<version>2.14</version>
</dependency>
net.sourceforge.htmlunit
htmlunit
2.14
添加排除项，如下所示：
<dependency>
<groupId>net.sourceforge.htmlunit</groupId>
<artifactId>htmlunit</artifactId>
<version>2.14</version>
**<exclusions>
<exclusion>
<groupId>net.sourceforge.nekohtml</groupId>
<artifactId>nekohtml</artifactId>
</exclusion>
</exclusions>**
</dependency>
net.sourceforge.htmlunit
htmlunit
2.14
**
net.sourceforge.nekohtml
内科特米尔
**
我认为您遇到的错误与pom.xml
文件中声明的依赖项无关。是的，删除旧版本的nekoHTML可以解决相同的错误。谢谢
