Lombok not working in a Netbeans project

问题

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 ?

回答1:

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>

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.

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

回答3:

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

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.
