<@s.introduction>
<p>
<a href="http://www.gwtproject.org/">GWT (Google Web Toolkit)</a> is compatible with lombok.
</p><p>
Edit your <code>proj-debug</code> and <code>proj-compile</code> batch scripts to add the following VM arguments:
<pre>
java <strong>-javaagent:lombok.jar=ECJ</strong> <em>(rest of arguments)</em>
</pre>
</p><p>
Thanks to Stephen Haberman for figuring this out.

<@s.section title="GWT plugin in Eclipse">
<p>
To use the GWT plugin in eclipse together with Lombok:<br />
Install lombok into eclipse as normal (start <code>lombok.jar</code> as an application).<br />
Download the JDT variant that GWT uses. For GWT v2.8.2 you'll need <a href="https://github.com/gwtproject/tools/raw/master/lib/eclipse/org.eclipse.jdt.core_3.11.2-CUSTOM-GWT-2.8-20160205.jar">org.eclipse.jdt.core 3.11.2</a>; for the current GWT development snapshot, this is <a href="https://github.com/gwtproject/tools/raw/master/lib/eclipse/org.eclipse.jdt.core_3.13.50-CUSTOM-GWT-20171215.jar">org.eclipse.jdt.core 3.13.50</a>. For more versions, search for jar files matching 'org.eclipse.jdt.core-{VERSION}-CUSTOM-GWT-{date}.jar in the <a href="https://github.com/gwtproject/tools/tree/master/lib/eclipse">lib/eclipse section GWT's github page</a>.<br />
Configure the 'GWT/Compile' option in the eclipse GWT plugin; in the advanced section, add the following VM arguments:<br />
<pre>-javaagent:/path/to/lombok.jar=ECJ
-Xbootclasspath/p:/path/to/lombok.jar:/path/to/org.eclipse.jdt.core_fromPreviousStep.jar</pre>
Where the colon should be replaced with a semicolon on windows.<br />
GWT Dev Mode needs a similar configuration: In the VM arguments section ('Arguments' tab), add:
<pre>-javaagent:/path/to/lombok.jar=ECJ</pre>
and in the 'Classpath' tab, add both lombok.jar and the org.eclipse.jdt.core file you downloaded.
