In the build.xml of my project I have a property defined:
<property name="somedir.dir" location="my_project/some_dir"/> The value of ${somedir.dir} will be an absolute path: /home/myuser/my_project/some_dir.
What I need is just the relative path ./my_project/some_dir without the ${basedir} value /home/myuser. How can I achieve this using Ant?
So far I found a solution by converting the property to a path and then use "pathconvert", but I don't think this is a nice solution:
<path id="temp.path"> <pathelement location="${somedir.dir}" /> </path> <pathconvert property="relative.dir" refid="temp.path"> <globmapper from="${basedir}/*" to="./*" /> </pathconvert> Any other (more elegant) suggestions?

The absolutePath function works by beginning at the starting folder and moving up one level for each "../" in the relative path. Then it concatenates the changed starting folder with the relative path to produce the equivalent absolute path.
In simple words, an absolute path refers to the same location in a file system relative to the root directory, whereas a relative path points to a specific location in a file system relative to the current directory you are working on.
Relative paths make use of two special symbols, a dot (.) and a double-dot (..), which translate into the current directory and the parent directory. Double dots are used for moving up in the hierarchy.
Since Ant 1.8.0 you can use the relative attribute of the Ant property task for this.
For example:
<property name="somedir.dir" location="my_project/some_dir"/> <echo message="${somedir.dir}" /> <property name="somedir.rel" value="${somedir.dir}" relative="yes" /> <echo message="${somedir.rel}" /> Leads to:
[echo] /home/.../stack_overflow/ant/my_project/some_dir [echo] my_project/some_dir A slightly less verbose solution would be specifying somepath inside <pathconvert>:
<pathconvert property="relative.dir"> <path location="${somepath}"/> <globmapper from="${basedir}/*" to="./*" /> </pathconvert> If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
