Delombok fails on Java 21

[pacphi]

While there's a work-around for Java 17, delombok-ing does not work for Java 21. I used sdkman to download and install Graal CE v21. Then I tried to compile a project of mine, see output.

❯ sdk install java 21-graalce

Downloading: java 21-graalce

Do you want java 21-graalce to be set as default? (Y/n): Y

Setting java 21-graalce as default.

There appears to be some related info mentioned here, projectlombok/lombok#3393. Adding edge-SNAPSHOT version works!

[dstango]

Did you notice the new release?
https://projectlombok.org/changelog

[basil]

@awhitford Please update lombok-maven-plugin to Lombok 1.18.30 and release a new version to fix this bug

[alecharp]

@awhitford I created #180 to update Lombok and Jacoco Maven plugin so this plugin can support Java 21.

[eivinhb]

This maven plugin seems to be dead in the water.

To work around the problem, just specify the dependency yourself.

<plugin>
    <groupId>org.projectlombok</groupId>
    <artifactId>lombok-maven-plugin</artifactId>
    <version>1.18.20.0</version>
    <executions>
        <execution>
            <phase>generate-sources</phase>
            <goals>
                <goal>delombok</goal>
            </goals>
        </execution>
    </executions>
    <dependencies>
        <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
            <version>${lombok.version}</version>
        </dependency>
    </dependencies>
</plugin>

Actually @eivinhb solution worked fine for me.

@awhitford would be great to be this project updated.

Thanks in advance.

For me, adding the Lombok Maven plugin for delombok produced no output underneath target/.
I am using Java 21.
