eclipse java annotation processing

Question

I want to do something using Annotation processing in eclipse jdt.

Eclipse jdtapt help tells me I should configure things on the java/compiler/annotation processing preferences page.

But on my installation (Indigo), the compiler section doesn't have this annotation processing subsection. It only has building,errors/warnings,javadoc, task tags.

Is something wrong with my installation ?

Answer 1

The annotation processing tab does not exist in the Preferences page that is accessible from the Eclipse menu bar. It is a project-specific menu that is accessible if you right-click on a project in the Project Explorer and select Preferences in the pop-up menu that will appear.

You may have to enable project-specific settings for the Java compiler tab and annotation processing explicitly before it will appear, as mentioned in this tutorial.

Answer 2

I autogenerate my eclipse project files, so I prefer setting this stuff w/o using the UI ...

project/.factorypath:

<factorypath>
    <factorypathentry kind="WKSPJAR" id="../build/EpicBuilder.jar" enabled="true" runInBatchMode="false"/>
</factorypath>

project/.settings/org.eclipse.jdt.apt.core.prefs:

eclipse.preferences.version=1
org.eclipse.jdt.apt.aptEnabled=true
org.eclipse.jdt.apt.genSrcDir=.apt_generated
org.eclipse.jdt.apt.reconcileEnabled=true

project/.settings/org.eclipse.jdt.core.prefs:

eclipse.preferences.version=1
org.eclipse.jdt.core.compiler.processAnnotations=enabled

Maybe you are running a multi-module project. You are looking for the annotation processing tab in the parent project which might have a <packaging>pom</packaging> in its pom.xml

If so, you won't find the tab here. Go to a specific project with packaging jar and you will see the tab.

I search for this a few hours, so maybe this helps someone saving time.

i spent full day , you can do it next way:

0. add lombok to maven pom.xml
1. install eclipse
2. download lombok
3. copy to eclipse folder
4. add to file eclipse.ini next text -javaagent:lombok.jar
