Generic javadoc command that always generates all javadocs in a given tree?

When I have to generate javadocs for a new, unfamiliar project, I find that I spend a long time trying to simply write the correct command, specifying all the packages, all the source trees, etc. It's time-consuming and error-prone: I'm probably missing some source.

So let's say I have a directory myproj, and underneath it there are a few packages (and various other resources and stuff), and under those package directories there are eventually some src/ directories, and then lots of my/awesome/java/project/package type structures.

Is there a s开发者_Go百科ingle command that will always recurse over EVERYTHING and generate ALL javadocs in one output location? I don't care how long it takes. Something brain-dead like javadoc -d doc -sourcepath . -subpackages * would be great. Failing that, what's the easiest way to generate all javadocs, no matter what the directory structure is?

Use find to find all Java source files and then send them to javadoc:

find . -type f -name "*.java" | xargs javadoc -d outputdir 

On Windows you can do it like this:

Generate file list:

dir /s /b *.java > file.lst

Generate javadoc:

javadoc -d outputdir @file.lst
