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. </p> <p> The above instructions are contributed by Stas via the forum.
