Maven编译失败(但Eclipse下的编译成功)

Question

从Eclipse构建我的Web项目时,一切都很好:没有错误,没有警告.

然而,在使用Maven构建项目时,它很脆弱.以下是输出形式mvn compile:

    ...

</project>

有人可以帮我解决这个问题吗？

您尚未将servlet类添加为依赖项.Eclipse中默认存在默认值,因此可以从那里进行编译.将以下内容添加到您的pom中(之前<build>...,从此处获取):

<dependencies>
  [...]
  <dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>servlet-api</artifactId>
    <version>2.4</version>
    <scope>provided</scope>
  </dependency>
</dependencies>
