Maven共有6类属性：

1.内置属性(Maven预定义,用户可以直接使用)

${basedir}表示项目根目录,即包含pom.xml文件的目录;
${version}表示项目版本;
${project.basedir}同${basedir};
${project.baseUri}表示项目文件地址;
${maven.build.timestamp}表示项目构件开始时间;
${maven.build.timestamp.format}表示属性${maven.build.timestamp}的展示格式,默认值为yyyyMMdd-HHmm,可自定义其格式,其类型可参考Java.text.SimpleDateFormat。用法如下：

<properties>
<maven.build.timestamp.format>yyyy-MM-dd HH:mm:ss</maven.build.timestamp.format>
</properties>

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 }

2.POM属性(使用pom属性可以引用到pom.xml文件对应元素的值)

${project.build.directory}表示主源码路径，缺省为target;
${project.build.outputDirectory} 构建过程输出目录，缺省为target/classes
${project.build.sourceEncoding}表示主源码的编码格式;
${project.build.sourceDirectory}表示主源码路径;
${project.build.finalName}表示输出文件名称，缺省为${project.artifactId}-${project.version};
${project.packaging} 打包类型，缺省为jar;
${project.version}表示项目版本,与${version}相同;

3.自定义属性

在pom.xml文件的

标签下定义的Maven属性

<project>
  <properties>
    <my.pro>abc</my.pro>
  </properties>
</project>

在其他地方使用${my.pro}使用该属性值。

4.settings.xml文件属性

与pom属性同理,用户使用以settings.开头的属性引用settings.xml文件中的XML元素值
${settings.localRepository}表示本地仓库的地址;

5.Java系统属性

所有的Java系统属性都可以使用Maven属性引用
使用mvn help:system命令可查看所有的Java系统属性;
System.getProperties()可得到所有的Java属性;
${user.home}表示用户目录;

通过System.getProperties()获取的java系统属性如下

6.环境变量属性

所有的环境变量都可以用以env.开头的Maven属性引用
使用mvn help:system命令可查看所有环境变量;
${env.JAVA_HOME}表示JAVA_HOME环境变量的值;s

mvn help:systems
