Question

I’m trying to store a relative path to a file in my ant build.xml like this:

<property name="foo" location="somedir/myfile" relative="true"/>

According to the Ant manual for Property this is ok syntax, but when running it Ant says:

property doesn’t support the
“relative” attribute

I’m using Apache Ant version 1.7.1 compiled on August 13 2009

Answer 1

Manual that came with 1.7.1 distribution does not mention relative property.

If you look at the top of ant manual link, it says 1.8.0RC1.
I guess these are new 1.8.0 attributes of property task.
Probably you should report a bug to the ant team to mark relative and basedir attributes as Since 1.8.0

On the other hand if you need a relative path to a basedir, just use a value attribute of property task.

— UPDATE

I’ve submitted a bug to ant team
