Java 22 support

[adityasamant25]

Firstly a big thanks for this project. It is a life-saver for Macs on the silicon chip.

Just a quick question, will there be support for Java 22 or does the project support LTS releases only?

[NotBjoggisAtAll]

Bump! I also want Java 22!

I didn't plan to push any more releases, because the upstream https://github.com/paketo-buildpacks now have multi-arch support for https://github.com/paketo-buildpacks/java and https://github.com/paketo-buildpacks/java-native-image AND they already have Java 22 support!

This is my new maven config:

    <plugin>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-maven-plugin</artifactId>
        <executions>
          <execution>
            <id>build-info</id>
            <goals>
              <goal>build-info</goal>
            </goals>
          </execution>
        </executions>
        <configuration>
          <image>
            <builder>paketobuildpacks/builder-jammy-buildpackless-tiny</builder>
            <buildpacks>
              <buildpack>paketobuildpacks/java</buildpack>
            </buildpacks>
            <env>
              <BPL_SPRING_AOT_ENABLED>true</BPL_SPRING_AOT_ENABLED>
              <BP_JVM_CDS_ENABLED>true</BP_JVM_CDS_ENABLED>
              <BP_JVM_VERSION>22</BP_JVM_VERSION>
            </env>
          </image>
        </configuration>
      </plugin>

or

<build>
    <plugins>
      <plugin>
        <groupId>org.graalvm.buildtools</groupId>
        <artifactId>native-maven-plugin</artifactId>
      </plugin>
      <plugin>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-maven-plugin</artifactId>
        <executions>
          <execution>
            <id>build-info</id>
            <goals>
              <goal>build-info</goal>
            </goals>
          </execution>
        </executions>
        <configuration>
          <image>
            <builder>paketobuildpacks/builder-jammy-buildpackless-tiny</builder>
            <buildpacks>
              <buildpack>paketobuildpacks/java-native-image</buildpack>
            </buildpacks>
          </image>
        </configuration>
      </plugin>
    </plugins>
  </build>

Spring Boot 3.3 now has CDS support, so the JVM images startup even faster!

Take the upstream multi-arch-buildpacks for a spin. If they don't work out for you, I'll deploy a new release!

@adityasamant25 @NotBjoggisAtAll I'll leave this open, but I really want you to try the upstream buildpacks, because they work! Let me know how it goes!

[lpellegr]

@dashaun Thanks a lot for the information and Maven example.

Here is the configuration for use with Gradle:

bootBuildImage {
    builder = 'paketobuildpacks/builder-jammy-buildpackless-tiny'
    buildpacks = ['paketobuildpacks/java-native-image']
}

The buildpack have multi-arch support but images they publish, like builder-jammy-tiny, are not multi-arch so builds runs via rosetta on MacOS and are much slower. Ticket to address that: paketo-buildpacks/builder-jammy-tiny#366
