Lombok annotations do not compile under Intellij idea

Question

1. I've installed the plugin for intellij idea(lombok-plugin-0.8.6-13).
2. Added lombok.jar into classpath
3. I can find getters and setters in the window of structure. And Intellij shows no error.
4. Setting - Lombok plugin - Verified Intellij configuration for lombok, it shows that "configuration of IntelliJ seems to be ok".

It seems everything is OK. But when I compile a test, errors come: can not find the methods getXXX and setXXX.

I opened the .class file with IntelliJ and find out that there is no setXXX and getXXX methods.

Could somebody tell me why?

• plugin:lombok-plugin-0.8.6-13
• lombok.jar:1.14.0
• idea:13.0.2 for linux
• jdk:1.7.0_21

Answer 1

In order to solve the problem set:

• Preferences (Ctrl + Alt + S)
  • Build, Execution, Deployment
    • Compiler
      • Annotation Processors
        • Enable annotation processing

Make sure you have the Lombok plugin for IntelliJ installed!

• Preferences -> Plugins
• Search for "Lombok Plugin"
• Click Browse repositories...
• Choose Lombok Plugin
• Install
• Restart IntelliJ

Answer 2

If you're using Eclipse compiler with lombok, this setup finally worked for me:

• IDEA 14.1
• Lombok plugin
• ... / Compiler / Java Compiler > Use Compiler: Eclipse
• ... / Compiler / Annotation Processors > Enable annotation processing: checked (default configuration)
• ... / Compiler > Additional build process VM options: -javaagent:lombok.jar

The most important part is the last one, mine looks like following:

Plugin is needed for IntelliJ editor to recognise getters and setters, javaagent is needed for eclipse compiler to compile with lombok.

Answer 3

For me, both lombok plugin and annotation processing enable needed, no else. No need to Use Eclipse and additional -javaagent:lombok.jar options.

• Idea 14.1.3, build 141.1010
• Lombok plugin[Preference->plugins->browse repositories->search 'lombok'->install and restart idea.
• Preference ->search 'annotation'->enter annotation processor ->enable annotation processing.

Answer 4

If you're using Intellij on Mac, this setup finally worked for me.

Installations: Intellij

1. Go to Preferences, search for Plugins.
2. Type "Lombok" in the plugin search box. Lombok is a non-bundled plugin, so it won't show at first.
3. Click "Browse" to search for non-bundled plugins
4. The "Lombok Plugin" should show up. Select it.
5. Click the green "Install" button.
6. Click the "Restart Intellij IDEA" button.

Settings:

1. Enable Annotation processor

   • Go to Preferences -> Build, Execution,Deployment -->Preferences -> Compiler -> Annotation Processors
   • File -> Other Settings -> Default Settings -> Compiler -> Annotation Processors

2. Check if Lombok plugin is enabled

   • IntelliJ IDEA-> Preferences -> Other Settings -> Lombok plugin -> Enable Lombok

3. Add Lombok jar in Global Libraries and project dependencies.

   • File --> Project Structure --> Global libraries (Add lombok.jar)

4. File --> Project Structure --> Project Settings --> Modules --> Dependencies Tab = check lombok

5. Restart Intellij

Answer 5

IDEA 2016.1:

• Install lombok plugin
• Settings -> Compiler -> Annotation Processors -> Enable annotation processing: checked (default configuration)
• Settings -> Compiler -> Annotation Processors -> Annotation Processors add "lombok.launch.AnnotationProcessorHider$AnnotationProcessor"

• Also if you are using maven add to maven-compiler-plugin configuration -> annotationProcessors -> annotationProcessor: lombok.launch.AnnotationProcessorHider$AnnotationProcessor

  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>${maven.plugin.compiler.version}</version>
    <configuration>
      <compilerVersion>${java.version}</compilerVersion>
      <source>${java.version}</source>
      <target>${java.version}</target>
      <annotationProcessors>
        <annotationProcessor>lombok.launch.AnnotationProcessorHider$AnnotationProcessor</annotationProcessor>
      </annotationProcessors>
    </configuration>
  </plugin>
  

Answer 6

Make sure these two requirements are satisfied:

1. Enable annotation processing,

   Preferences > Build, Execution, Deployment > Compiler > Annotation Processors > Enable annotation processing

2. Lombok plugin is installed and enabled for your project.

Answer 7

After spending far too long troubleshooting this, I found a simple workaround which ensures IntelliJ processes Lombok annotations correctly during builds.

The gradle-lombok plugin is not necessary for this workaround. Your build.gradle only requires the following:

dependencies {
    compileOnly("org.projectlombok:lombok:1.16.18")
}

The workaround is to turn on the following IntelliJ setting:

1. Open IntelliJ preferences/settings.
2. Navigate to Build, Execute, Deployment > Build Tools > Gradle > Runner
3. Check the box labeled Delegate IDE build/run actions to gradle

Benefits of this workaround compared to other solutions on this page:

• No annotation processing necessary!
• Able to use the Java compiler of your choice (no Eclipse compiler necessary)
• No use of buggy gradle-lombok plugin (although perhaps someone else can solve this)
• No VM options necessary
• No hard-coded paths to lombok jar

One downside is that IntelliJ will no longer use its own test runner. Instead, tests are always run through Gradle.

Answer 8

None of the advanced answers to this question resolved the problem for me.

I managed to solve the problem by adding a dependencie to lombok in the pom.xml file, i.e. :

<dependency>
   <groupId>org.projectlombok</groupId>
   <artifactId>lombok</artifactId>
   <version>1.16.12</version>
</dependency>

I am using IntelliJ 2016.3.14 with maven-3.3.9

Hope my answer will be helpful for you

Answer 9

On Itellij 15 CE, it's enough to just install Lombok Plugin (no additional configuration required).

Answer 10

I followed this procedure to get ride of a similar/same error.

mvn idea:clean

mvn idea:idea

After that I could build both from the IDE intellij and from command line.

Answer 11

I am unable to get this working with the javac compiler, and I get the same error.

Error:(9, 14) java: package lombok does not exist

I have enabled annotation processor, and have also tried rebuilding the project, invalidate cache/restart. Doesn't help.

I did however get it to work partially with eclipse compiler. I say partial because although the build passes successfully, the editor still complains about "Cannot resolve symbol".

Idea - 15.04 community edition Lombok - 1.16.6 Lombok plugin (https://github.com/mplushnikov/lombok-intellij-plugin) - 0.9.8 JDK - 1.8.0_51

Update: Ok, I finally got this working. Mine was a gradle project, and lombok was configured as a custom "provided" configuration. Worked fine after adding this in build.gradle

idea {
 module {
     scopes.PROVIDED.plus += [configurations.provided]
    }
}

So, 3 steps

1. Install Lombok plugin from File->Settings->Plugins
2. Enable Annotation Processor (javac compiler works too)
3. Ensure that you have build.gradle or pom.xml updated for idea if you are adding lombok as a custom config.
