The old 'disableCheckedExceptions' branch wasn't a particularly nice distribution/storage model of experimental features. For example, it was hopelessly out of date. Redesigned to a separate experimental directory, along with new build scripts, and rewrite it to the new lombok.patcher model.
Unfortunately it doesn't actually work, just yet. Seems to do nothing at all.

<h1>Tired of checked exceptions?</h1>
|
||||
<p>
|
||||
This lombok spinoff project consists of a hack that only works in javac - not eclipse or any other IDE.<br />
|
||||
It will completely disable the notion of checked exceptions. You may throw any exception anywhere, and you may
|
||||
also catch any exception anywhere. In standard javac, you may not catch a checked exception that is not declared
|
||||
as thrown by at least 1 statement in your try block, unless it is <code>Exception</code> or <code>Throwable</code>.<br />
|
||||
This restriction is lifted as well.
|
||||
</p>
|
||||
<h3>Usage</h3>
|
||||
<p>
|
||||
Just make sure <code>disableCheckedExceptions-alpha.jar</code> is on the classpath as you compile. For example:<br />
|
||||
<code>javac -cp disableCheckedExceptions-alpha.jar MySource.java</code>
|
||||
</p>
|
||||
<p>
|
||||
Ready to try it out? download it here: <a href="downloads/disableCheckedExceptions-alpha.jar">disableCheckedExceptions-alpha.jar</a>
|
||||
</p>
|
||||
<p>
|
||||
Want to know how its done? Grab the <em>disableCheckedExceptions</em> branch of project lombok. You can browse and download the branch <a href="http://github.com/rzwitserloot/lombok/tree/disableCheckedExceptions">here on github</a>.
