Available Variables
Project Model Variables

Any field of the model that is a single value element can be referenced as a variable. For example, ${project.groupId}, ${project.version}, ${project.build.sourceDirectory} and so on. Refer to the POM reference to see a full list of properties.

These variables are all referenced by the prefix "project.". You may also see references with pom. as the prefix, or the prefix omitted entirely - these forms are now deprecated and should not be used.
Special Variables
basedir The directory that the current project resides in.
project.baseUri The directory that the current project resides in, represented as an URI. Since Maven 2.1.0
maven.build.timestamp The timestamp that denotes the start of the build. Since Maven 2.1.0-M1

The format of the build timestamp can be customized by declaring the property maven.build.timestamp.format as shown in the example below:

<project>
  ...
  <properties>
    <maven.build.timestamp.format>yyyyMMdd-HHmm</maven.build.timestamp.format>
  </properties>
  ...
</project>

The format pattern has to comply with the rules given in the API documentation for SimpleDateFormat. If the property is not present, the format defaults to the value already given in the example.
Properties

You are also able to reference any properties defined in the project as a variable. Consider the following example:

<project>
  ...
  <properties>
    <mavenVersion>2.1</mavenVersion>
  </properties>
  <dependencies>
    <dependency>
      <groupId>org.apache.maven</groupId>
      <artifactId>maven-artifact</artifactId>
      <version>${mavenVersion}</version>
    </dependency>
    <dependency>
      <groupId>org.apache.maven</groupId>
      <artifactId>maven-project</artifactId>
      <version>${mavenVersion}</version>
    </dependency>
  </dependencies>
  ...
</project>

maven2 其实用JDK1.4.2也可以编译的

3 楼 zerostar88 2010-02-11  

mvn package -Dmaven.test.skip=true

  在maven中有完整的开发生命周期,但有时候却不能按自己的想法灵活的设置一些任务,这就想到了ANT(我想到的maven的开发者们也想到了,所以有一个maven-antrun-plugin),可以在maven中执行ant任务.
       在Maven中执行ant任务有两种方法:
       1、在pom.xml中直接写ANT任务
 
<build>
    <plugins>
       <plugin>
        <artifactId>maven-antrun-plugin</artifactId>
        <executions>
          <execution>
            <phase>generate-sources</phase>
            <goals>
              <goal>run</goal>
            </goals>
            <configuration>
              <tasks>
                <copy todir="E:workspaceRB_MyFaces argetclasses">
                  <fileset includes="hibernate.cfg.xml" dir="E:workspaceRB_MyFacessrcmainjava"></fileset>
                  <fileset includes="MessageResources.properties" dir="E:workspaceRB_MyFacessrcmainjava"></fileset>
                </copy>
              </tasks>
            </configuration>
          </execution>
        </executions>
      </plugin>
    </plugins>
  </build>

       2、在pom.xml中调用ANT文件
       把上例中的<tasks></tasks>中的任务移到一个build.xml文件中,然后加入下面这句话
<ant antfile="build.xml" target="default" />
就可以执行build.xml文件中 default任务了.

三种方案。
1.使用jetty进行测试，有maven插件，这个是嵌入式的，速度要快很多。
Java代码
<plugin> 
               <groupId>org.mortbay.jetty</groupId> 
               <artifactId>maven-jetty-plugin</artifactId> 
               <version>6.1.5</version> 
               <configuration> 
                   <scanIntervalSeconds>10</scanIntervalSeconds> 
               </configuration> 
           </plugin>

<plugin>
                <groupId>org.mortbay.jetty</groupId>
                <artifactId>maven-jetty-plugin</artifactId>
                <version>6.1.5</version>
                <configuration>
                    <scanIntervalSeconds>10</scanIntervalSeconds>
                </configuration>
            </plugin>
直接执行Java代码
mvn jetty:run

mvn jetty:run
2.要使用tomcat 也不难，最简单的方法使用NetBeans，从plugin中安装maven插件，这样，你可以直接在项目属性中选择使用tomcat 等，并且它同样支持增量开发（Compile on Save , Deploy on Save）
3.使用 Cargo（刚刚发布了1.0）maven 插件管理 tomcat，一样的轻松方便。参考
http://cargo.codehaus.org/Maven2+Plugin+Tips

3.maven 打包命令
mvn war:war
但有的时候可能会打包失败


mvn -o package -Dmaven.test.skip=true

  这条语句基本都可以成功。

4.maven 生成javadoc
mvn javadoc:javadoc
