I moved this post from eclipse.platform.pde to here.
I tried to export Ant build file using the Ant buildfiles export wizard.
However, it seemed it did not handle linked java files. For example, I
have a simple java project which contains a linked java file in the source
folder. I export the Ant build file for this project. I check the
generated Ant build file but did not find anything in the file which
handles the linked java file. I ran it outside of eclipse and the linke
file was not compiled. If there is a linked folder, I saw the generated
Ant build file handled it correctly. I am not sure if this is a
un-implemented feature? or it is not supposed to be supported?
