====这里不知道干撒用的，URL连接都不能用，但也写在这儿===

            </snapshots>
        </repository>
    </repositories>

==重要！！ MAVEN所有的动作都依赖这里，下面一个一个讲===

    <build>

这个不用说了：）
        <resources>
            <resource>
                <directory>src/main/java</directory>
                <includes>
                    <include>**/*.xml</include>
                </includes>
            </resource>
        </resources>

==PLUGINS，PLUGINS！！编译打包、部署全靠他们了==

        <plugins>

默认的 编译用的
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId> 
                <configuration>
                    <source>${java-version}</source>
                    <target>${java-version}</target>
                </configuration>
            </plugin>

默认的 打WAR 包的

<plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-war-plugin</artifactId>
                <configuration>
                    <warName>tradinghub</warName>
                </configuration>
            </plugin>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-dependency-plugin</artifactId>
                <executions>
                    <execution>
                        <id>install</id>
                        <phase>install</phase>
                        <goals>
                            <goal>sources</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>

===这里浪费了我好多的时间，想用他的一个JBOSS部署，让打包后的WAR文件直接投到JBOSS的部署目录中去

这个和上面的WAR的功能是一样的。。只是这个不是默认的，无法执行到，我找了半天也没有找到在哪里可以改。。也可能根本 就不能改！

用法：

CMD下：

mvn jboss:hard-deploy             意思是让打好的WAR包直接COPY到指定的目录中，他依赖PACKAGE这个动作，后面有总结的用法。。。

            <plugin>
                <groupId>org.codehaus.mojo</groupId>
                <artifactId>jboss-maven-plugin</artifactId>
                <version>1.4.1</version>
                <configuration>
                    <jbossHome>E:/jboss-4</jbossHome>
                    <serverName>default</serverName>
                    <fileName>
                        ${project.build.directory}/tradinghub.war
                    </fileName>
                </configuration>
            </plugin>

不知道干撒用的，不关心

            <plugin>
                <groupId>org.codehaus.mojo</groupId>
                <artifactId>aspectj-maven-plugin</artifactId>
                <!–
                    Have to use version 1.2 since version 1.3 does not appear to work
                    with ITDs
                –>
                <version>1.2</version>
                <dependencies>
                    <!–
                        You must use Maven 2.0.9 or above or these are ignored (see
                        MNG-2972)
                    –>
                    <dependency>
                        <groupId>org.aspectj</groupId>
                        <artifactId>aspectjrt</artifactId>
                        <version>${org.aspectj-version}</version>
                    </dependency>
                    <dependency>
                        <groupId>org.aspectj</groupId>
                        <artifactId>aspectjtools</artifactId>

                    </dependency>
                </dependencies>
                <executions>
                    <execution>
                        <goals>
                            <goal>compile</goal>
                            <goal>test-compile</goal>
                        </goals>
                    </execution>
                </executions>
                <configuration>
                    <outxml>true</outxml>
                    <source>${java-version}</source>
                    <target>${java-version}</target>
                </configuration>
            </plugin>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-surefire-plugin</artifactId>
                <configuration>
                    <junitArtifactName>junit:junit</junitArtifactName>
                    <excludes>
                        <exclude>**/*_Roo_*</exclude>
                    </excludes>
                </configuration>
            </plugin>

        </plugins>
    </build>
</project>

主要就是这个文件了，下面简单说下用法

配置文件搞好后，运行它有两个办法：

1.在ECLIPSE中

用maven build会有很多的框要你填，头晕，只要填写GOALS就可以了，举例：

clean package jboss:hard-deploy

撒意思？这个三个GOAL，每个中间用空格隔开。

clean 是把以前BUILD的清干净

package  是打包的意思，这个GOAL会完成编译打WAR包的动作

JBOSS:HARD-deploy的意思是把打包好的文件COPY的指定的JBOSS目录中去。。

2.在CMD中

mvn clean package jboss:hard-deploy

这就可以了。

这个小东西NND搞了好几天，当然还有很多的小细节就不一一细说了，其实是个很简单的东西，感觉还没有ant好用，只是多了个LIB包集中管理而已，语法太TM晦涩了，特别是命令行参数，看了就晕。。希望这些对新同学们有用。 

关于MAVEN的LIB包，简单举个例子

        <dependency>
            <groupId>mysql</groupId> 这个就是放包的外层文件夹
            <artifactId>mysql-connector-java</artifactId>这个是JAR文件名
            <version>5.1.2</version>这个是JAR文件版本
        </dependency>

文件名和文件版本最头晕，其实也是超简单，为撒就不能给我们说明白了，我看了半天，其实就是把一个文件分成两半就行了，中间用“-”隔开的。

比如上面这个的JAR文件就是：mysql-connector-java-5.1.2.jar       必须的：）

想要自己加个包时就这么搞就行了。名字你胡乱写都 可以，只要记住两半规则和文件夹层次

就这么一东西，哎。。怎么就没人把它这样简单的说说明白呢！！
