Can't compile project when I'm using Lombok under IntelliJ IDEA

Question

I'm trying to use Lombok in my project that I'm developing using IntelliJ IDEA 11.

I've installed 3rd-party plugin for IDEA and it seems working fine because IDEA sees all autogenerated methods/fields.

So I have a class that uses Slf4j. I annotated it like this

import lombok.extern.slf4j.Slf4j;

@Slf4j
public class TestClass
{
    public TestClass()
    {
        log.info("Hello!");
    }
}

But when I build my project compiler spits: cannot find symbol variable log.

Could you please tell me what I'm missing here?

Update: It turned out it's RequestFactory annotation process that fails.

input files: {com.zasutki.courierApp.server.TestServlet, com.mine.courierApp.server.model.DatastoreObject}

annotations: [javax.inject.Singleton, javax.inject.Inject, lombok.Getter, lombok.Setter, com.googlecode.objectify.annotation.Id, com.googlecode.objectify.annotation.OnSave]

Processor com.google.web.bindery.requestfactory.apt.RfValidator matches [lombok.Getter, com.googlecode.objectify.annotation.Id, javax.inject.Inject, lombok.Setter, com.googlecode.objectify.annotation.OnSave, javax.inject.Singleton] and returns false.

cannot find symbol variable log

Any ideas on workarounds?

Update2: Perhaps it's not something readers want to hear but I ended up switching to Scala.

Errors appear even without the plugin. I am not able to run tests of a project if Lombok is in my pom.xml dependencies. — Nowaker, Feb 26 '12 at 21:57

I have fixed it in IDEA 12 by setting check box Enable annotation processing in:

Settings -> Compiler -> Annotation Processors

For IDEA 2016.2:

Preferences... > Build, Execution, Deployment > Compiler > Annotation Processors

After enabling, run Build -> Rebuild Project to have annotations recognized and eliminate errors.

For IDEA 2019.2.1, depending on how the project is configured, installing the Project Lombok plugin may not be sufficient. Here is another way to use Project Lombok with IntelliJ IDEA:

Visit https://projectlombok.org/download
Download the JAR file into the project lib directory (e.g., $HOME/dev/java/project/libs).
Start the IDE.
Click File Settings.
Expand Build, Execution, Deployment Compiler Annotation Processors.
Ensure Enable annotation processing is checked.
Ensure Store generates sources relative to is selected based on the project's module settings (if Module output directory doesn't work, come back and try the other setting).
Click Apply.
Click Plugins.
Click Marketplace.
Set search field to: lombok
Install Lombok.
Click OK.
Restart the IDE if prompted.
Click File Project Structure.
Select Libraries.
Click the + symbol to add a new project library (or press Alt+Insert).
Select Java.
Set the path to: $HOME/dev/java/project/libs/lombok.jar
Click OK.
Select the modules to apply.
Click OK.
Optionally, rename lombok to Project Lombok 1.18.8.
Click OK.

The project can now import from the lombok package and use Project Lombok annotations (e.g., lombok.Setter and lombok.Getter).

I had to stop my Win10 for a freeze issue (pilot crash) and IntelliJ was opened. At restart, I guess idea files in my project directory has been altered (workspace.xml) and after that I couldn't generate my getters/setters methods via lombok. "Canno't find symbol" at build time. I wrestled a bit to spot the origin of the issue. – Alex May 20 '16 at 08:42

Don't forget to set annotation processor: lombok.launch.AnnotationProcessorHider$AnnotationProcessor for both maven-compiler-plugin and Idea (Settings -> Compiler -> Annotation Processors) – Jan Kubovy Jun 15 '16 at 15:38

This isn't working for me in 2016.2. Maven web project. The only thing that worked was installing the lombok plugin. – maksimov Sep 15 '16 at 10:24
Idea 16.2.2 + gradle + installed lombok plugin. I could run project without this when using the gradle runscript (from idea). If I wanted to run directly (since this is the only way I know to make code hotswap work) I had to enable annotation processing. Guess idea does not automatically fully configure project and annotations don't get processed despite the plugin? – Neikius Oct 20 '16 at 15:20
Worked for me in IDEA 2017.01. Installing Lombok worked for Intellisense, but not for compilation until Annotation Processor was enabled. – lreeder May 24 '17 at 16:38
For IDEA 2017.3.2, re-installing the Lombok plugin (Uninstall, restart, Install and restart) worked for me. – Antonio Saco Jan 09 '18 at 11:33
After doing it, I still needed to remove and reimport the project as a maven project – Carlos Alberto Schneider Jul 23 '18 at 17:28
Without the plugin the above is irrelevant. Install the Lombok plugin AS WELL AS the good advice in the answer above :=). Also applies to Intellij 2018.2 btw. – Beezer Mar 18 '19 at 13:38
In my case, I wasn't seeing a warning message before the errors, saying that plugin Lombok had been disabled because of [delegating issues](https://github.com/mplushnikov/lombok-intellij-plugin/issues/620). Turned out Idea was trying to use Java 11 to compile. After downgrading to Java 1.8, everything worked fine. – user5365075 Jul 25 '19 at 12:58

Make sure it's added correctly to your project.

example for Gradle:

 dependencies {
     compileOnly 'org.projectlombok:lombok:1.18.8'
     annotationProcessor 'org.projectlombok:lombok:1.18.8'
     ...
 }

Install Lombok plugin for your IDE
Check "Enable annotation processing" checkbox in IDE (IntellijIdea), have no idea if there is anything like this for other IDEs like Eclipse.

First enable annotation processors and try. This may or may not work.

Post that, you can install the lombok plugin from intellij, (After installation Intellij will restart to enable the plugin, so make sure you save your work.(Intellij does save all the changes before restart, just to be on the safe side.)) screenshot below:

I didn't need to use the -javaagent approach, neither setup the classpath.

Just for reference using IntelliJ 2018.3, I solved this issue (using @Data annotation to insert getter/setter) following the three steps:

File -> Settings -> Build, Execution, Deployment -> Annotation Processors -> Enable Annotation Processing;

Do remember to Apply the change.

Install plugin lombok in the same setting dialog;

It seems good enough for now, it requires to restart IntelliJ and then rebuild your project.

Did you had maven or gradle? I am having a problem making lombok work for a multi module project. I keep getting the error: `Error:java: Annotation processing is not supported for module cycles. Please ensure that all modules from cycle [module-core,module-utils] are excluded from annotation processing` – 0x01Brain Jun 04 '20 at 06:40

If you have checked both these steps as follows

Enable annotations : this is a check done in IntelliJ preferences.
Importing lombok into IntelliJ classPath (Preferences -> Plugins)

and still getting errors then please check the compiler - if it is JAVAC or ECLIPSE.

You can check the compiler in Preferences -> Build,Execution,Deployment -> Compiler -> Java Compiler.

Change the Use compiler to Javac (if it is Eclipse). This is what worked for me.

As noted here, quote: "You should activate external compiler option and enable annotation processors or disable external compiler and disable all of annotation compilers to work with lombok". This fixed my problem. Note that I added the Scala plugin prior to receiving this error, so I suspect the plugin changed some of the above settings.

It may happen that even if you have it configured properly and it is visible among the libraries and in Gradle dependencies list, IntelliJ still does not have it in class path. Or it is there, but configured with different scope (ex: test instead of compile.)

First, make sure you have plugin installed and annotation processing enabled, as stated in other answers.

If you still have annotation not recognized, place cursor on it, hit ALT+ENTER (or OPTION+ENTER) and see if you have a menu option Add library: Gradle: org.projectlombok:lombok:VERSION to class path. If you can see it, choose this one and it may solve your problem.

You may check the library and it's scope in: Project settings / Modules / Dependencies tab (search for lombok in there)

This solution should be much more upvoted. I was investigating this for hours, and this was the only thing that worked. — Devon, Mar 12 '21 at 02:45

I faced a similar problem. The following worked for me.

download (from here https://projectlombok.org/download) and add the jar in your project structure.

If lombok libs are set correctly, as many mentioned above, click on the annotation that wouldn't compile, Alt-Enter, a correct import will appear, and the code will compile. - it took me a while to figure it out. I put it here just in case people may miss the simple obvious.

For Eclipse users on MacOS, do this. It worked for me.

Copy lombok.jar into Eclipse.app/Contents/MacOS directory.
Add -javaagent:lombok.jar to the end of Eclipse.app/Contents/Eclipse/eclipse.ini file.
Restart Eclipse and enable “Annotation Processing” in project properties.

After enabling annotator processors I had to update to the newest version of lombok:

    <dependency>
        <groupId>org.projectlombok</groupId>
        <artifactId>lombok</artifactId>
        <version>1.18.16</version>
    </dependency>

Intellij version:

This happened to me because the JDK version that runs the building process is too low. Lombok was built with JDK 1.7 or up. The build be must run with Java version 1.7 or up.

I had to disable the @Document annotation that I'd just added. I'm converting my project to use Mongo instead of Postgres, and it was previously working, but it seems @Document conflicts with Lombok's @Getter

My issue was that the bundled version of Lombok plugin in IntelliJ IDEA was incompatible with the version of IntelliJ IDEA itself. I downgraded IntelliJ to 2019.1.4 and it worked.

I had the same problem, but non of the answers given here worked for me. The error message I was getting on the import lombok.val imports:

intellij lombok cannot resolve symbol

I'm using IntelliJ "IDEA 2022.3.1 (Community Edition)". Apparently IntelliJ scans the classpath for annotation processing, so adding lombok not for compilation only, but also for runtime worked for me:

Use

implementation 'org.projectlombok:lombok'

instead of

compileOnly 'org.projectlombok:lombok'

Similar issue came up during SpringBoot migration to version 3.x.x+. @ConstructorBinding annotation doesn't work with Lombok, it has to be removed

In my case, to make it work on some classes defined in the tests using java code in a plain kotlin project (no android) without the kapt plugin, I had to do in my build.gradle.kts:

    dependencies {
        compileOnly("org.projectlombok:lombok:1.18.20")
        annotationProcessor("org.projectlombok:lombok:1.18.20")
        ...
        testCompileOnly("org.projectlombok:lombok:1.18.20")
        testAnnotationProcessor("org.projectlombok:lombok:1.18.20")
    }

Then "Build" -> "Rebuild project" was working.

If you will use the kapt plugin, you should be able to remove the annotationProcessor lines. But I had to deal without kapt in my case.

To get this working, simply install the "Lombok Plugin" for IntelliJ. You don't need to do anything with enabling "Annotation Processors", as some other commentors have suggested. (I've tested this with the latest version of IntelliJ IDEA, currently 2017.1.2). To install the plugin, go to Settings, then Plugins, then click the "Browse repositories" button, then search for "Lombok", and install the Lombok Plugin. You will be prompted to restart IntelliJ. Afterwards, you should be able to compile from IntelliJ, and you won't receive any more error inspections.
