ANT : How to get User, OS name and Environment properties

Here is what you need to do if you want to fetch below in/using ANT:

a. Logged user - built-in property
b. Machine OS name - built-in property
c. Environment properties - ANT provides a property task which has an attribute environment. Thus if you specify the task with environment="myenv" you will be able to access OS-specific environment variables via property names "myenv.PATH" or "myenv.TERM".


Below is a sample ant script.

<?xml version="1.0" encoding="UTF-8" standalone="no"?>

<project basedir="." default="systeminfo">

  <target name="systeminfo">

    <property environment="my_env" />

    <echo>

      User is ${user.name}

      OS Name is ${os.name}     

      ANT_HOME is set to ${my_env.ANT_HOME}

    </echo>

  </target>

</project>

Output:

BuildFile: build.xml systeminfo

[echo]

[echo] User is nadimwarsi

[echo] OS Name is Windows 10 Enterprise

[echo] ANT_HOME is set to C:\Program Files\Java\jdk1.7

[echo] BUILD SUCCESSFUL
