kotlin-class-access-bug

This project aims to reproduce a bug with Kotlin plugin for IntelliJ, as described at (https://youtrack.jetbrains.com/issue/KT-26535)

Project Setup

• Clone this repository

git clone https://github.com/cotej/kotlin-class-access-bug

• Open the IntelliJ project at kotlin-class-access-bug/app
  • This is a Kotlin application, which depends on a Java library libupper, which in turn depends on another Java library liblower.
  • If prompted, configure a Java SDK for the project.
  • Using Maven (either on CLI or in IntelliJ panel), install the libraries and compile the app.

mvn -f liblower/pom.xml install
mvn -f libupper/pom.xml install
mvn -f app/pom.xml compile

• Open app/App.kt in the editor. At this point, all should be well. The project compiles in both IntelliJ and Maven, no errors are reported, and can be run.

Revealing the Error

• Edit upperlib/pom.xml and change the version to 2.0.0.
• Now we make a trivial change to app/pom.xml to force IntelliJ to reload its pom.
  • Edit app/pom.xml and change the <name> element by appending a . to the end
• Return to app/App.kt in the editor, and suddenly a Cannot access class error appears on line 8.
  • However, the project still compiles in IntelliJ and Maven! And it runs! The app project still depends on version 1.0.0 of upperlib which is installed in our local Maven repository, so there should be no issue.
