Question

您好我正在尝试在台式机上安装Hibernate v4.0.0.CR2，它需要Maven才能运行。

我为Maven设置了所需的环境变量，并尝试从命令行构建maven。当我从Maven中的bin目录（在我的桌面上）的命令提示符中运行命令'mvn 3.0.3'时，我收到错误：

 D:\Documents and Settings\user\Desktop\apache-maven-3.0.3\bin>mvn

我的POM.xml文件位于Maven的bin目录中：

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

         <!-- Because this is a web app, we also have a dependency on

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

         <!-- Hibernate uses slf4j for logging, for our purposes here
 use the simple backend -->
         <dependency>
             <groupId>org.slf4j</groupId>
             <artifactId>slf4j-simple</artifactId>
         </dependency>

         <!-- Hibernate gives you a choice of bytecode providers
 between cglib and javassist -->
         <dependency>
             <groupId>javassist</groupId>
             <artifactId>javassist</artifactId>
         </dependency>
     </dependencies> </project>

我正在关注网站上的Hibernate教程，以了解Hibernate在工作中的使用情况，但我偶然发现了这个问题。

我出错的任何想法？

谢谢！

Hibernate不需要Maven。 Maven只是一个构建工具。
运行Maven的命令是mvn，而不是mvn 3.0.3。
正如错误告诉您的那样，您必须为每个依赖项提供一个版本。换句话说，与<groupId>和<artifactId>一起，您必须指定<version>元素。

Maven构建错误
