Lombok not working in a Netbeans project

Question

I want to use Lombok in a project to use @Getter and @Setter.

I included using Maven:

    <dependency>
        <groupId>org.projectlombok</groupId>
        <artifactId>lombok</artifactId>
        <version>1.12.6</version>
        <scope>provided</scope>
    </dependency>

Import is OK for Netbeans:

import lombok.Getter;
import lombok.Setter;

But auto setters and getters don't work (no autocompletion / "cannot find symbol ...").

Strange thing is that for another project I have it's working fine! But I can't figure the differences.

I tested to:

• change the lombok version (even the last): for any version, the import don't work anymore

• build the project with Maven: it's OK!

• use Eclipse: it's OK! (but I am the only one to decide unfortunately)

=> so I'm sure this is a Netbeans related problem

• enable annotation processing, as I've seen in tutorials=> I don't have such option in my project properties

Any idea ?

Answer 1

This worked with us:

• remove <scope>provided</scope> from the Lombok dependency
• clean and build the project
• change the Lombok version (we changed from 1.16.20 to 1.16.16)
• clean and build the project
• restore the Lombok version and put back <scope>provided</scope>
• clean and build the project

I found a solution on https://groups.google.com/forum/#!topic/project-lombok/xbgzA86pvJs

=> update version of maven-compiler-plugin was the only way to make it work

Answer 3

configure the pom

<properties>
    <src.dir>src/main/java</src.dir>
</properties>

<profiles>
    <profile>
        <id>lombok-build</id>
        <properties>
            <src.dir>${project.build.directory}/generated-sources/delombok</src.dir>
        </properties>
    </profile>
</profiles>

<dependencies>
<dependency>
    <groupId>org.projectlombok</groupId>
    <artifactId>lombok</artifactId>
    <version>1.16.8</version>
    <scope>provided</scope>
</dependency>
</dependencies>
    <build>
        <sourceDirectory>${src.dir}</sourceDirectory>
    <plugins>
        <plugin>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok-maven-plugin</artifactId>
            <version>1.16.16.0</version>
            <executions>
                <execution>
                    <phase>generate-sources</phase>
                    <goals>
                        <goal>delombok</goal>
                    </goals>
                    <configuration>
                        <sourceDirectory>src/main/java</sourceDirectory>
                        <addOutputDirectory>false</addOutputDirectory>
                    </configuration>
                </execution>
            </executions>
        </plugin>
    </plugins>
</build>

Then, specify lombok-build as the active profile for various actions (build, debug etc) under Project Properties->Actions->Activate Profiles.

At this blog there is a github sample project and the configuration with pictures to use lastest version of maven+netbeans+lombok, that works for me.

Answer 4

In Netbeans 8.2 using Apache Maven 3.5.4 use Lombok 1.18.4 or much older 1.16.16.

In Netbeans 10.0/9.0 using Apache Maven 3.5.4 use Lombok 1.18.4, older versions of Lombok are really buggy when Compile On Save is used in Netbeans 10.0/9.0

I updated Lombok to a new version

<dependency>
    <groupId>org.projectlombok</groupId>
    <artifactId>lombok</artifactId>
    <scope>provided</scope>
    <version>1.18.8</version> <!--1.18.8 for Netbeans 9/10 OR 1.16.16 for Netbeans 8 with Java 8 -->
</dependency>

NB

• For maven-compiler-plugin, remove any annotationProcessorPaths to do with Lombok in the maven-compiler-plugin
• Remove any Lombok maven plugins

This is not needed, as Maven and Netbeans does this out of the box. You only need the right Lombok dependency in Maven.
