maven惯用配置的变量

maven常用配置的变量
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

${basedir} represents the directory containing pom.xml${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

${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

${settings.localRepository } refers to the path of the user's local repository.${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

${env.M2_HOME } returns the Maven2 installation path.${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

<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

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().
