Appengine deployment file count

Question

What contributes to the number of files that are created? I assume the number of gwt permutations is a multiplier, but what factors sum up to the constant variable? static files, source files, etc? What, if anything, should I keep in mind to keep the file count low(er)?

Answer 1

Everything that ends up in the war folder, including compiled gwt modules, compiled java code, static files, jars, etc.

Scanned 2500 files. Cloning 962 static files. Cloning 1693 application files.

/war -> 1793 files

/war/ -> 478*2+30 -> 986 files /war/WEB-INF -> 744 files

/war/WEB-INF/classes -> 655 files
