title: How to configure Java Annotation Processor(s) in Eclipse?
body: <p>I have successfully run annotation processor for CLASS level retention annotations via command prompt compiling using Java 8. </p>
  
  <p>However, when I tried to configure the annotation processor in eclipse and tried to run it with <code>"-proc:only"</code> option, it didn't get effective.</p>
  
  <p>I have included the Jar file containing the custom annotation processor class file into the <code>Project Properties -&gt; Annotation Processing -&gt; Factory Path</code>. I have also provided the <code>-proc:only</code> option in <code>Project Properties -&gt; Annotation Processing -&gt; Processor Options</code>, still the annotation processor isn't getting called when a class containing my annotation is executed.</p>
  
  <p>Please help me identifying the required setting or mistake or additional step for running the annotation processor via eclipse.</p>
