   Hi Subrat Katiyar (@subratkatiyar), I'm an AI Support assistant here to help with your issue. While the team reviews your request, I wanted to provide some possible tips and documentation that might help you in the meantime.

   Solution

   • Upgrade Tycho to a version that includes the JavaSE-19 execution environment (EE) profile. Tycho 3.0.4 ships with support for JavaSE-19.
     • In your root POM, set the Tycho version to 3.0.4:

     <properties>
       <tycho.version>3.0.4</tycho.version>
     </properties>

     • Or in pluginManagement:

     <pluginManagement>
       <plugins>
         <plugin>
           <groupId>org.eclipse.tycho</groupId>
           <artifactId>tycho-maven-plugin</artifactId>
           <version>${tycho.version}</version>
         </plugin>
       </plugins>
     </pluginManagement>
