Maven找不到包和符号

问题描述：

我有一个具有以下课程的应用:(课程的一部分):

I have an app with these class: (part of class):

@SessionScoped
@Named
public class UserSessionBean implements Serializable {

    @javax.ws.rs.core.Context private HttpServletRequest httpRequest;

在mvn编译期间，出现此错误:

and during mvn compile, I have this error:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:2.3.1:compile (default-compile) on project highway-web: Compilation failure: Compilation failure:
[ERROR] /home/kelevra/java/git/ttkHighway/highway-web/src/main/java/com/kmware/ttk/highway/beans/session/UserSessionBean.java:[28,25] package javax.servlet.http does not exist
[ERROR]

[ERROR] symbol  : class HttpServletRequest
[ERROR] location: class com.kmware.ttk.highway.beans.session.UserSessionBean
[ERROR] -> [Help 1]

在IDEA中制作时不会出现此类问题.可能是什么?

While making in IDEA there is no such problems. What it could be?

答

Java文件UserSessionBean找不到类HttpServletRequest.

Java file UserSessionBean can not find the class HttpServletRequest.

您应该检查pom文件中声明的依赖项.确保您包含

You should check the dependencies declared in the pom file. Make sure that you include

 <dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>servlet-api</artifactId>
    <version>2.5</version>
    <scope>provided</scope>
  </dependency>

您可以尝试执行mvn全新安装，看看是否会产生相同的错误.

Could you try a mvn clean install and see if it produces the same error.

P.S.您是从控制台还是从IDE运行项目.

P.S. Are you running the project from console or from an IDE.
