java - 使用 Maven 时出现 "package does not exist"错误

Question

我正在使用 Maven 构建 HelloWorld 程序。但我失败了

mvn package

错误消息是:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-    plugin:3.1:compile (default-compile) on project QuickStart: Compilation failure: Compilation failure:
[ERROR] /Users/xxx/java/QuickStart/src/main/java/hello/Greeting.java:[3,43] package org.hibernate does not exist
[ERROR] /Users/xxx/java/QuickStart/src/main/java/hello/Greeting.java:[8,9] cannot find symbol
[ERROR] symbol:  class Session 
[ERROR] location: class hello.Greeting

而且我发现如果我手动编译 Greeting.java，一切都会正常工作，这是为什么？谢谢。

Greeting.java 是如此简单:

package hello;

import org.hibernate.Session;

public class Greeting {

    public Greeting() {
        Session session;
    }

}

我的 pom.xml 是从 spring.io 复制的:

  <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

尝试添加此依赖项:

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-context-support</artifactId>
</dependency>
