Maven构建错误

Question

嗨我试图在我的台式机上安装Hibernate v4.0.0.CR2，它需要Maven来运行。

我为Maven设置了所需的环境变量，并试图从命令行构建maven。当我从Maven的（这是我的桌面上）的bin目录命令提示符下运行命令“MVN 3.0.3”我得到的错误：

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

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

我pom.xml文件是在bin目录中Maven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

    <artifactId>hibernate-tutorial</artifactId> 
    <version>1.0.0-SNAPSHOT</version> 
    <name>First Hibernate Tutorial</name> 

    <build> 
      <!-- we dont want the version to be part of the generated war 
file name --> 
      <finalName>${artifactId}</finalName> 
    </build> 

    <dependencies> 
     <dependency> 
      <groupId>org.hibernate</groupId> 
      <artifactId>hibernate-core</artifactId> 
     </dependency> 

     <!-- Because this is a web app, we also have a dependency on 
the servlet api. --> 
     <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> 

我按照网站上的Hibernate的教程，去感受在工作，但是我已经在这个问题迷迷糊糊中使用Hibernate的。

任何想法，我哪里出错了？

谢谢！

1. Hibernate不需要Maven。 Maven只是一个构建工具。
2. 运行Maven的命令是mvn，而不是mvn 3.0.3。
3. 由于错误告诉你，你必须为每个依赖提供一个版本。换句话说，与<groupId>和<artifactId>一起，您必须指定一个<version>元素。
