Lombok Requires Annotation Processing

lombok requires annotation processingannotation processing seems to be disabled for the project

I'm using Android Studio 2.2 Preview 7, and the Lombok plugin suddenly started saying: Annotation processing seems to be disabled for the project X, and providing a link to settings.

Clicking on the notification does not take me to the right place.

What is the fix for this?


Android Studio“lombok requires annotation processing”, After Lombok plug-in installation, I face an error saying “lombok requires annotation processing”. I solved the problem by following steps. Expand Compiler and choose Annotation Processors; Make sure you have Enable annotation processing and "Obtain processors from project classpath" enabled; Last but not least update your projects build.gradle file with the snippet below. Ignore the hint that its deprecated, since it's not using (until now. See issue).


With the newer gradle versions, it is enough to type these lines into the app's build.gradle's dependencies block:`

compile "org.projectlombok:lombok:1.16.16"
annotationProcessor "org.projectlombok:lombok:1.16.16"  

Sync the project with the gradle and it will work.

Setting up Lombok with Eclipse and Intellij, Lombok uses annotation processing through APT, so, when the compiler calls it, the library generates new source files based on annotations in the originals. Annotation processing isn't enabled by default, though. Enable annotation processing box is checked. Obtain processors from project classpath option is selected. Lombok as an Annotation Processor Java allows application developers to process annotations during the compilation phase; most importantly, to generate new files based on an annotation. As a result, libraries like Hibernate allow developers to reduce the boiler-plate code and use annotations instead.


First, I don't think removing your project from the welcome screen can have any effect. Just think about it, removing your project from "recent projects" on that screen does not re-create it, how could changing Default settings have any effect on an existing project?

To enable annotation processing in an existing project you don't need to delete anything. Go to YourAwesomeProject/.idea/compiler.xml and make sure you have value "true" in following attribute: /project/annotationProcessing/profile@enabled.

Like this:

<?xml version="1.0" encoding="UTF-8"?>
<project version="4">
  <component name="CompilerConfiguration">
    ...
    <annotationProcessing>
      <profile default="true" name="Default" enabled="true"><!-- here -->
        <processorPath useClasspath="true" />
      </profile>
    </annotationProcessing>
  </component>
</project>

You might need to File -> Invalidate Caches / Restart

Misleading error for Lombok plugin on Android Studio � Issue #264 , Lombok Requires Annotation Processing Annotation processing seems to be disabled for the project "AtixPos". For plugin to function correctly,� For Lombok to work, we need to turn on annotations processing. To do that, go to File -> Settings -> Build, Execution, Deployment -> Compiler -> Annotation Processors and mark “Enable annotation processing”.


For those who have the same problem using Android Studio 2.4+ its not solved by doing any hints above except Janis Peisenieks answer.

Open your Intellij IDEA 2017 / Android Studio 2.4+ and go to (Windows)

  1. File->Other Settings->Default Settings
  2. Expand Build, Execution, Deployment
  3. Expand Compiler and choose Annotation Processors
  4. Make sure you have Enable annotation processing and "Obtain processors from project classpath" enabled
  5. Last but not least update your projects build.gradle file with the snippet below. Ignore the hint that its deprecated, since it's not using (until now. See issue).

    defaultConfig {
        javaCompileOptions {
            annotationProcessorOptions {
                includeCompileClasspath = true
            }
        }
    }
    

Found out that there is a very simple way doing this without all those changes above!

If you set your processor in the gradle like lombok you wont use only provided or testCompile. You need to add this using annotationProcessor aswell into your dependencies. Example:

dependencies {
    provided "org.projectlombok:lombok:1.16.16"
    annotationProcessor "org.projectlombok:lombok:1.16.16"
}

Thank you to Jack Wharton for butterknife where i figured out how he solved it.

Hint: You may need to invalidate cache and restart to get it working for some annotation processors like lombok.

Change linked text in Lombok Requires Annotation Processing , The "Lombok Requires Annotation Processing" notification says: Annotation processing seems to be disabled for the project "bo-client". Lombok Requires Annotation Processing Annotation processing seems to be disabled for the project “JavaApiAutoTest”. But lombok is on classpath. For the lombok plugin to function correctly,


Probably marked answer was sufficient at the time but I struggled a bit with android studio 3 and lombok 1.16.18. Anyway following worked for me

in app > build.gradle add following

compileOnly 'org.projectlombok:lombok:1.16.18'
annotationProcessor 'org.projectlombok:lombok:1.16.18'

you may start getting other errors so if you in your MyApplication > lombok.config add following lines

lombok.addGeneratedAnnotation = false
lombok.anyConstructor.suppressConstructorProperties = true

if you don't have lombok.config just added it

Above were suggested by the developer of lombok in following posts addGeneratedAnnotation suppressConstructorProperties

Android, It is important to configure your android project properly to make sure lombok add Lombok to your application's dependencies block (requires Gradle v2.12 or newer): compileOnly 'org.projectlombok:lombok:1.18.12' annotationProcessor � Go to Preferences -> Build, Execution,Deployment -->Preferences -> Compiler -> Annotation Processors. File -> Other Settings -> Default Settings -> Compiler -> Annotation Processors. Check if Lombok plugin is enabled. IntelliJ IDEA-> Preferences -> Other Settings -> Lombok plugin -> Enable Lombok.

IDEA News: Lombok Requires Annotation Processing, IDEA News: Lombok Requires Annotation Processing, Programmer Sought, the best programmer technical posts sharing site. Lombok can easily generate the constructors, both no arguments and with fields. We need to add annotation @NoArgsConstructor to generate the implicit no-argument constructor and @RequiredArgsConstructor to add required field constructor. Also, to make a field required, we need to add @NonNull in the field itself like below.
