<property environment="env"/>
<echo message="TMP = ${env.TMP}"/>
The environment variables can be accessed in Ant by creating a property for the environment and assigning it a name. The variables can then be accessed using the property name.
This example shows the content of the tmp environment variable in the output. First, the environment is loaded in the env property. Then the tmp variable is accessed using ${env.TMP}. After the value is written in the output.
<project name="MyProject" default="test" basedir=".">
<target name="test">
<!-- Load the environment properties -->
<property environment="env"/>
<!-- Show the TMP in the output -->
<echo message="TMP = ${env.TMP}"/>
</target>
