Gradle provides an "incremental compilation" mode which very significantly improves the edit/build/debug cycle time, particularly if used in conjunction with a real-time class loader such as that built into Spring Boot or JRebel.

As of gradle version 5, annotation processors have to provide additional code & configuration to gradle to support this mode.

JpaModelGen Version 5.4.2.Final has not been updated to provide that support, meaning that any time the :compile gradle task is executed, all source files in the project are re-compiled.

Use of the model generator is widespread, and support of gradle incremental mode could have a major impact on reducing development time throughout the design community.
