maven的变量

maven定义了很多变量属性,参考这里
http://docs.codehaus.org/display/MAVENUSER/MavenPropertiesGuide

1)内置属性
Xml代码  收藏代码
${basedir} represents the directory containing pom.xml 
${version} equivalent to ${project.version} or ${pom.version} 


2)Pom/Project properties
所有pom中的元素都可以用 project. 前缀进行引用,以下是部分常用的
Xml代码  收藏代码
${project.build.directory } results in the path to your "target" dir, this is the same as ${pom.project.build.directory } 
${project.build. outputD irectory } results in the path to your "target/classes" dir 
${project.name } refers to the name of the project. 
${project.version } refers to the version of the project. 
${project.build.finalName } refers to the final name of the file created when the built project is packaged 


3)本地用户设定
所有用的的 settings.xml 中的设定都可以通过 settings. 前缀进行引用
Xml代码  收藏代码
${settings.localRepository } refers to the path of the user's local repository. 
${maven.repo.local } also works for backward compatibility with maven1 ?? 


4)环境变量
系统的环境变量通过 env. 前缀引用
Xml代码  收藏代码
${env.M2_HOME } returns the Maven2 installation path. 
${java.home } specifies the path to the current JRE_HOME environment use with relative paths to get for example:  
<jvm>${java.home}../bin/java.exe</jvm> 


5)java系统属性
所有JVM中定义的java系统属性.

6)用户在pom中定义的自定义属性
Xml代码  收藏代码
<project>  
    ...  
    <properties>  
        <my.filter.value>hello</my.filter.value>  
    </properties>  
    ...  
</project> 

则引用 ${my.filter.value } 就会得到值 hello

7)上级工程的变量
Xml代码  收藏代码
上级工程的pom中的变量用前缀 ${project.parent } 引用. 上级工程的版本也可以这样引用: ${parent.version }.maven的变量 


8)引用属性Reflection Properties
The pattern ${someX.someY.someZ} can simply sometimes mean getSomeX().getSomeY().getSomeZ(). Thus, properties such as ${project.build.directory} is translated to getProject().getBuild().getDirectory().
