Inspectopedia 2026.1 Help

Redundant default constructor

Reports usages of zero-argument constructor for JPA entities.

Instead of having zero-argument constructor explicitly in the code, it is recommended to use kotlin-jpa compiler plugin and omit that constructor.

kotlin-jpa compiler plugin generates an additional zero-argument constructor for classes with a specific annotation.
