Java projects can contain many different versions of dependencies; some of which are dependent on each other. Ensuring that all of the environmental conditions are compatible is a time consuming job; and if left incorrect can lead to spurious behaviours in your application. Furthermore, to successfully write unit tests, Cover requires tests dependencies to be available at the correct versions.
In this release we have redesigned the Project Environment Health Check to clearly show plugin dependency issues in your project (such as mismatched versions of Spring dependencies) and in many cases automatically fix the issue for you by adding or upgrading dependencies. If Cover finds any issues it will clearly indicate with a X or ! next to the dependency and provide you with a "Fix issue..." button. If multiple issues are detected Cover will provide a "Fix all issues..." button to fix all of the issues that it has found.

Resolved an issue which, in some circumstances, caused Cover to create time-sensitive assertions which pass on the day the test was written, but fail afterwards. [Ref: TG-18709]
Resolved an issue which, depending on javac compile options, could cause Cover to incorrectly treat some methods as trivial. [Ref: TG-18695]
