Title: Kotlin-Java Interoperability Not Working in Cursor IDE

Issue Description

Cursor IDE cannot resolve Kotlin classes from Java files, while the same code works correctly in IntelliJ IDEA.

Specific Problem

• Java code cannot resolve Kotlin classes despite being in the same package
• Error shown in Cursor: "XXXX cannot be resolved to a variable"
• Same code builds and runs correctly in IntelliJ IDEA

Project Setup

• Maven project with kotlin-maven-plugin
• Mixed Java-Kotlin codebase
• Both files in same package

Maven Configuration

<plugin>
    <artifactId>kotlin-maven-plugin</artifactId>
    <groupId>org.jetbrains.kotlin</groupId>
</plugin>

Attempted Solutions

1. Proper import statement added
2. Restarted Cursor
3. Cleared Cursor cache
4. Reloaded project
5. Project builds and runs correctly outside Cursor

Expected Behavior

Cursor should recognize and resolve Kotlin classes from Java code, similar to IntelliJ IDEA.
