Add a new line to a file (ANT)

How do you append lines in ANT?

Two basic things to know:

• echo task
• The ant property ${line.separator}

        <echo message="First line. ${line.separator}" file="test_file.txt"/>
        <echo message="Second line ! ${line.separator}" file="test_file.txt" append="true"/>

Notice the "append" attribute on the second echo!

That's all!
