You can fix this problem by finding files which holds finder information.

In terminal, goto project root directory and execute

ls -alR@ . > kundapura.txt

This creates kundapura.txt in current directory. Now search for com.apple.FinderInfo and clear this attributes for all files. You can do it like this

xattr -c <filename>

Example: xattr -c guru.png

  find . -type f -name '*.jpg' -exec xattr -c {} \;
  find . -type f -name '*.png' -exec xattr -c {} \;
