Maven: mvn install导致编译失败。

Question

Maven: mvn install导致编译失败。

4

当运行命令“mvn clean”时，它返回构建成功，但是当运行“mvn install”时，它返回编译失败。请帮我追踪引起错误的原因。提前致谢。

编辑：添加日志。

编辑2：顺便说一下，我正在使用Eclipse Indigo IDE和Glassfish 3.1。

[错误] 符号: 变量HttpServletResponse [错误] 位置: 类 com.project.Interceptor 问题出在这里，但您没有包含输出的关键部分，该部分会具体说明编译错误。mvn clean 删除了以前构建的所有痕迹，因此很少会失败，mvn install 实际上开始编译您的Java代码，因此如果代码有问题，它将产生像您收到的编译错误一样的编译错误。 - SpellingD

@SpellingD，感谢您的建议。我使用了“import javax.servlet.http.HttpServletRequest;”，保存后代码中没有出现任何编译错误，但在运行“mvn install”之后却出现了错误。 - iamtheexp01

你应该将第一次出现错误的日志部分，包括在 BUILD FAILURE 之前。它应该位于 <project name> 后面的文本块中。 - SpellingD

@SpellingD，日志已更新。我不知道为什么无法找到HttpServletResponse。我需要添加什么吗？ - iamtheexp01

您缺少一些Java EE的依赖项，请尝试在您的pom.xml文件中添加以下依赖项（您可能需要更多）：

<dependency>
  <groupId>javax.servlet</groupId>
  <artifactId>servlet-api</artifactId>
  <version>2.4</version>
</dependency>

希望这能帮到你。
