Lombok @Builder not recognised by IntelliJ

Question

I updated IntelliJ IDEA to version 2018.2.7, and Lombok's @Builder annotation is not recognised anymore. The project already had Lombok annotations, which worked fine with previous (2017...) version of IntelliJ. Only @Builder is failing. I am using Lombok version 1.14.4. And Java 11.

The problem is similar to this one: Lombok not working with Intellij But the solution provided there is not applicable for my project as my project does not have a submodule and the only pom.xml is referring to the correct project.

The project has Lombok plugin and Annotation processing enabled.

Project's POM where version is configured:

<properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <lombok.version>1.14.4</lombok.version>
        <hibernate-jpa-2.1-api.version>1.0.0.Final</hibernate-jpa-2.1-api.version>
        <assertj-core.version>3.8.0</assertj-core.version>
</properties>

The error message at code level is: Cannot resolve symbol @Builder. If possible I would like to keep Lombok's and IntelliJ version.

Answer 1

Update your lombok version.

Because @Builder gained @Singular support and was promoted to the main lombok package since lombok v1.16.0.

I have

 <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
            <version>1.16.20</version>
            <scope>provided</scope>
            <optional>true</optional>
        </dependency>

and haven't that problem

Answer 2

I did no specify the version on my pom.xml and it got the latest version by default(1.18.8 I see this under External Libraries)

<dependency>
  <groupId>org.projectlombok</groupId>
  <artifactId>lombok</artifactId>
  <optional>true</optional>
</dependency>

The Class.builder() was not working for me but after installing the plugin(https://github.com/mplushnikov/lombok-intellij-plugin) it worked.

no extra configuration required. :)

Answer 3

In my case this is a problem with the version. Honestly. I downgrade to Version 1 and re-sync the Maven repositories:

    <dependency>
        <groupId>org.projectlombok</groupId>
        <artifactId>lombok</artifactId>
        <version>1.18.20</version>
        <scope>provided</scope>
    </dependency>
