ecj (the eclipse standalone compiler) is compatible with lombok. Use the following command line to enable lombok with ecj:
<p>
<pre>java <strong>-javaagent:lombok.jar=ECJ</strong> -jar ecj.jar -cp lombok.jar -source 1.8 <em class="note">(rest of arguments)</em></pre>
<p>
You may have to add the following VM argument, if you're using an older version of lombok or java:
<pre><strong>-Xbootclasspath/p:lombok.jar</strong></pre>
<p>
If you're using a tool based on ecj, adding these VM arguments and adding lombok.jar to the classpath should work.

<h3>Using ecj with Maven</h3>
<p>
It is possible to <a href="pom.xml">configure</a> <code>maven-compiler-plugin</code> with <code>maven-dependency-plugin</code> and <code>plexus-compiler-eclipse</code>.
</p>
<p>
Before the <code>compile</code> phase, you will have to set your <code>MAVEN_OPTS</code> environment variable to include the <code>javaagent</code> argument.
In the example below, <code>target</code> is your <code>${project.build.directory}</code>.
</p>
<p>
Use the following commands in sequence to enable lombok with ecj in your Maven build:
<pre>
mvn clean <strong>dependency:copy@get-lombok</strong>
set MAVEN_OPTS=<strong>-javaagent:target/lombok.jar=ECJ</strong> <em class="note">(or your OS's equivalent)</em>
mvn install
set MAVEN_OPTS= <em class="note">(or your OS's equivalent)</em>
</pre>
