Ant Javadoc task fails

Question

Hello I have a simple ant build script to generate javadoc for a bunch of projects.

The ant script is:

<project name="javadocs" default="doc" basedir=".">

What it looks like is happening is that Javadoc is being invoked with each java file as part of the parameter list, obviously this won't work because Windows has a limit on the size of the parameter that you can pass to programs. Any help appreciated as to how to make this work.

The beginning of your stack-trace is informative:

C:\\work\\icade_svn\\build_javadoc.xml:19: Javadoc failed: java.io.IOException: Cannot run program "C:\\Program Files\\Java\\jdk1.7.0_15\\bin\\javadoc.exe": CreateProcess error=206, The filename or extension is too long

It seems there is good information related to this problem:
