How can I get ant to list TODO: tags found in my code in the build output when I run it. I would like build failure to be optional (ie: a setting) if they are found.

---

I've tried Checkstyle as suggested in the related post, but it doesn't display the text of the TODO:.

IE:

[checkstyle] .../src/Game.java:36: warning: Comment matches to-do format 'TODO:'.
[checkstyle] .../src/Game.java:41: warning: Comment matches to-do format 'TODO:'.
[checkstyle] .../src/GameThread.java:25: warning: Comment matches to-do format 'TODO:'.
[checkstyle] .../src/GameThread.java:30: warning: Comment matches to-do format 'TODO:'.
[checkstyle] .../src/GameThread.java:44: warning: Comment matches to-do format 'TODO:'.

I am not sure if this provides the ability to fail a build if a todo is found but it may be usefull http://code.google.com/p/ant-todo/
