Does Flex Builder support relative path in compiler arguments, like I want to specify relative path for my services-config.xml?
Yes, Flex Builder does provide relative path when resolving compiler arguments. The current directory will be the flex source directory.
Suppose my Flex project has the following directory structure
So in Project Properties -> Flex Compiler -> Additional Compiler Arguments, I specify -services with relative path as follows
Noted that the current directory Flex Builder using to resolve any relative path in compiler arguments is the Flex Source directory.
Flex Builder also provides a variable that can be used in compiler arguments, i.e.: ${flexlib}, which refers to the Flex SDK Path in your machine.
${flexlib} = /Developer/Applications/eclipse/Adobe Flex Builder 3
