IntelliJ IDEA cannot see Lombok generated code [duplicate]

Answer 1

You need to enable the annotation preprocessor. See documentation here.

Additionally you should install the lombok plugin if not done already

Answer 2

In my case the issue occurred after updating IntelliJ via Toolbox.

"Enable annotation processing" flag was switched off (despite importing the settings from previous IntelliJ version), so I switched it on. This did not resolve the issue after restart, clean, build.

However, resintalling the lombok plugin helped!

EDIT: Seems that it was the problem with compatibility of lombok plugin with IntelliJ 2018.1, plugin upgrade to 0.17 is required for IntelliJ users.

Lombok plugin changelog excerpt:

Lombok support plugin updated to v0.17: - Fixed (#465): Fix plugin compatibility with IntelliJ 2018.1

Answer 3

Add below dependency in pom.xml along with other solutions mentioned in other answers.

<dependency>
    <groupId>org.projectlombok</groupId>
    <artifactId>lombok</artifactId>
    <version>1.18.2</version>
    <scope>provided</scope>
</dependency>

Answer 4

After enabled the annotation processor and installed lombok plugin, if still got "can't find symbol error" on lombok generated method, try check the gradle configuration, which is in

Preference -> Build,Execution, Deployment -> Gradle,

if you are using local gradle distribution, change to use default gradle wrapper.

I got this error when my project's gradle wrapper is 4.10.2 but my local gradle version is 5.1.1, and I solve it after I change it to use default gradle wrapper.

Answer 5

Even after adding annotation processor and having lombok dependency added might not solve the problem . This is because the class files related to model needs to be in target folder

Run clean install to generate the class files for model with lombok code generated changes.

Answer 6

Try click on lombok import, and put alt+enter, then short list will appear, choose add maven dependency, then on the right down corner on the screen will appear icon that maven should be enabledd, click on enable automatically. For me it worked.
