maven常用配置的变量

[size=medium]maven的变量[/size]

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

[size=medium]1)内置属性[/size]

${basedir} represents the directory containing pom.xml
${version} equivalent to ${project.version} or ${pom.version}

[size=medium]2)Pom/Project properties [/size]
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

${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

[size=medium]3)本地用户设定 [/size]
所有用的的 settings.xml 中的设定都可以通过 settings. 前缀进行引用

${settings.localRepository } refers to the path of the user's local repository.
${maven.repo.local } also works for backward compatibility with maven1 ??

[size=medium]4)环境变量 [/size]
系统的环境变量通过 env. 前缀引用

${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>

[size=medium]5)java系统属性 [/size]
所有JVM中定义的java系统属性.

[size=medium]6)用户在pom中定义的自定义属性[/size]

<project> 
    ... 
    <properties> 
        <my.filter.value>hello</my.filter.value> 
    </properties> 
    ... 
</project>

则引用 ${my.filter.value } 就会得到值 hello

[size=medium]7)上级工程的变量 [/size]

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

[size=large]8)引用属性Reflection Properties[/size]
[size=medium][color=red]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().
