Maven 项目不适用于 Tomcat 7

Question

我试图在 Tomcat 7 上运行 Maven 项目，但它似乎不起作用。当我从命令提示符 mvn clean tomcat7:run 中输入时，出现此错误:

我已经尝试了所有方法，包括尝试在其他计算机上运行该项目。在 4 台计算机中，它在 2 台上运行，但在另外 2 台上不运行。您认为这是 Maven 还是 Tomcat 的问题？

Answer 1

它实际上是在寻找正确的版本，我通过使用以下依赖项解决了它:

    <dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>javax.servlet-api</artifactId>
        <version>LATEST</version>
        <scope>provided</scope>
    </dependency>

希望对您有所帮助! PS - 使用正确的版本，我使用的是最新版本，删除任何其他与 servlet 相关的依赖项并只保留这个。
