Automatically find and resolve project dependency issues in the IntelliJ Plugin
To get the best results from the Diffblue Cover IntelliJ Plugin we check that you have compatible versions of dependencies. Until now you have had to manually adjust your Maven/Gradle configuration to do this. In Diffblue Cover 2023.01.02 we provide a link to fix all issues which will add required dependencies as necessary to get the best results from Diffblue Cover.

Validate your project is ready to run Diffblue Cover CLI
Much like the Diffblue Cover IntelliJ Plugin, to get the best results from Diffblue in the shortest time possible it is important that your project is structured in the best way and with supported versions of dependencies. In this release, we introduce the unlicensed --preflight option which allows you to ensure that your project is ready for Diffblue Cover. Use preflight to find common problems in Maven/Gradle project structures as well as checking that the dependencies in your project are compatible.
