 # VSCode Extension for Java + Kotlin
 
-A VSCode extension that enhances [vscode-java](https://github.com/redhat-developer/vscode-java) and [vscode-kotlin](https://github.com/fwcd/vscode-kotlin) with java + kotlin interoperability. This uses a JDT LS extension with a delegate command handler that can work together with the Kotlin Language Server, in order for Java code to have access to Kotlin code.

 **Disclaimer**: This is very experimental, but it seems to work for small maven and gradle projects at least.
