Java preview feature in Mapstruct

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.

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.
