<h3>Overview</h3>
<p>
<strong>This feature is considered 'workaround status' - it exists in order to allow users of lombok that cannot work without this feature to have access to it anyway. If we find a better way to implement this feature, or some future java version introduces an alternative strategy, this feature can disappear without a reasonable deprecation period. Also, this feature may not work in future versions of javac. Use at your own discretion.</strong>
</p><p>
Most annotations that make lombok generate methods or constructors can be configured to also
make lombok put custom annotations on elements in the generated code.
</p><p>
<code>@Getter</code>, <code>@Setter</code>, and <code>@Wither</code> support the <code>onMethod</code>
option, which will put the listed annotations on the generated method.
</p><p>
<code>@AllArgsConstructor</code>, <code>@NoArgsConstructor</code>, and <code>@RequiredArgsConstructor</code> support the <code>onConstructor</code> option which will put the listed annotations on the generated constructor.
</p><p>
<code>@Setter</code> and <code>@Wither</code> support <code>onParam</code> in addition to <code>onMethod</code>; annotations listed will be put on the only parameter that the generated method has.
</p><p>
None of the mentioned annotations above actually have parameters named <code>onMethod</code>, <code>onParam</code>, or <code>onConstructor</code>; nevertheless, if you type them, lombok will make it work. Unfortunately this does mean that auto-complete and other tool-driven convenience features will not work as expected. The annotations lack these parameters in order to work around javac limitations.

<h3>Small print</h3><div class="smallprint">
<p>
We can't think of any small print for this feature, other than to reiterate: This feature can disappear at any time; if you use this feature, be prepared to adjust your code when we find a nicer way of implementing this feature, or, if a future version of javac forces us to remove this feature entirely with no alternative.
</p><p>
The <code>onX</code> parameter is not legal on any type-wide variant. For example, a <code>@Getter</code> annotation on a class does not support <code>onMethod</code>.
