Robert Muir updated LUCENE-5593:
--------------------------------
Attachment: LUCENE-5593.patch
Attached is a patch ensuring javadocs are only built if they are out of date.
This also ensures they are only built once for each module.
Today imagine the following:
* A/
* B/ depends on A/
* C/ depends on B/
we currently build A 3 times, B twice, and C once. So we do 6 javadocs builds.
With the patch we only build A once, B once, and C once.
> javadocs generation in release tasks: painfully slow

> Something is wrong here in the way this generation works, I see some of the
> same javadocs being generated over and over and over again.
> The current ant tasks seem to have a O(n!) runtime with respect to how many
> modules we have: its obnoxiously slow on a non-beast computer. There is a bug
> here...
