For reference, here’s the relevant configuration snippet for your project’s pom.xml and more detailed documentation on how to install a minimal JRE with JLink:


<plugin>
  <groupid>org.springframework.boot</groupid>
    <artifactid>spring-boot-maven-plugin</artifactid>
    <configuration>
      <image>
        <env>
          <bp_jvm_jlink_enabled>true</bp_jvm_jlink_enabled>
        </env>
      </image>
  </configuration>
</plugin>

<groupid>org.springframework.boot</groupid>

<artifactid>spring-boot-maven-plugin</artifactid>

<image>

<env>

<bp_jvm_jlink_enabled>true</bp_jvm_jlink_enabled>

</env>

</image>

</configuration>

</plugin>
