it is works fine, but this code not

        <exec executable="cd ">
           <arg value="/home"/>
        </exec>

Why does't work "cd" command ? Can anybody help me?

Answer 1

you cannot "execute" cd from ant. cd is not an executable. cd is a shell builtin.

if you are trying to change the current working directory then you can use the dir attribute of the exec task.
