[FIXED] Java preview feature in Mapstruct

Issue

I am facing issues with mapstruct while running the code in Intellij

java: classfile for /C:/Users/workspace/ng-service/target/classes/org/converter/RepresentationConverterImpl.class 
uses preview features of Java SE 15. (use --enable-preview to allow loading of classfiles which contain preview features)

Because of the error above I am not able to run the app on Intellij's latest version 2022. I tried adding --enable-preview in pom.xml as well as in Intellij compiler but still no luck.

It is working fine with Intellij-2021. The person who uses preview features of java 15 left the organization and now all are suffering to use old intellij version.

                    </configuration>
                </plugin>

I tried following most of resources on web to fix the issue but not finding any working solution.

thank you

Solution

This issue is resolved by java in open JDK 17. Just tested the code with having a preview feature and with the latest IntelliJ 2022 and it's working as expected.
