我的项目在 ant 上运行良好。考虑将它移动到 maven，甚至包括 tomcat 作为依赖项，这样我就不必单独安装 tomcat。

当我执行 mvn tomcat:run 时；它能够构建应用程序并在tomcat启动时出现以下错误

我的 pom.xml 具有以下依赖项：

<dependency>
    <groupId>org.apache.tomcat</groupId>
    <artifactId>servlet-api</artifactId>
    <version>6.0.35</version>
</dependency>
<dependency>
    <groupId>org.tuckey</groupId>
    <artifactId>urlrewritefilter</artifactId>
    <version>4.0.4</version>
</dependency>

我什至尝试更改 tuckey 的版本。

你手上肯定有依赖冲突。我的建议是：

  1. 依赖于标准servlet-api工件，而不是 Tomcat 的
  2. 使用provided 范围，这样servlet-apijar 就不会被捆绑到您的 web 应用程序中。Tomcat 不希望你包含它，如果你包含它，它会发出警告。

然后你的 POM 应该有这个片段：

<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>javax.servlet-api</artifactId>
    <version>3.0.1</version>
    <scope>provided</scope>
</dependency>
<dependency>
    <groupId>org.tuckey</groupId>
    <artifactId>urlrewritefilter</artifactId>
    <version>4.0.4</version>
</dependency>

open you .m2 and locate the urlrewritefilter-3.1.0.pom. just copy the java servlet dependancy and add it to you pom. by example if you are using version 3.0.1, you must add this

<dependency>
            <groupId>javax.servlet</groupId>
            <artifactId>servlet-api</artifactId>
            <version>2.3</version>
            <scope>provided</scope>
        </dependency>

hope this help.
