Explain how to modify properties in ANT.
We can not modify the properties in ant. The properties in ant are immutable in nature.
Explain how to modify properties in ant.
Ant properties are immutable; they cannot be changed once initialized. However, it can be done in the following way although it causes the immutable property violation:
<?xml version="1.0"?>
<project name="example" default="run">
<taskdef name="groovy"
classname="org.codehaus.groovy.ant.Groovy"
classpath="lib/groovy-all-1.1-rc-1.jar"/>
<target name="run">
<echo>java.library.path = ${java.library.path}
<groovy>
properties["java.library.path"] = "changed"
</groovy>
<echo>java.library.path = ${java.library.path}
</target>
</project>
