I’m running Eclipse 2018-09 (curren version) and had the eclipse plugin version 0.8.7. I am building maven projects with Kotlin 1.2.71. Ever since I upgraded the plugin in eclipse with the release of Kotlin 1.3 my maven projects that include Kotlin code fail with this error: `Project configurator "org.jetbrains.kotlin.maven.projectConfigurator" required by plugin execution "org.jetbrains.kotlin:kotlin-maven-plugin:1.3.0:test-compile (execution: test-compile, phase: test-compile)" is not available. To enable full functionality, install the project configurator and run Maven->Update Project Configuration.` I tried upgrading kotlin in my maven projects to 1.3.0 but this hasn’t helped.

What can be wrong? Cheers, Tim ---
