Solving the Issue of Executing Kotlin Scripts from Rust on Windows

If you're a developer working with both Kotlin and Rust, you may encounter issues when attempting to execute Kotlin scripts from within Rust, especially on a Windows environment. This challenge might arise due to file permissions, incorrect file paths, or a lack of understanding of how Windows handles script execution. In this post, we will walk through the problem and provide a clear solution so you can successfully run your Kotlin scripts from Rust.

The Problem: Access Denied Error

In your journey to run Kotlin scripts via Rust, you may encounter an error message similar to the following:

This error typically indicates that the file you are attempting to execute doesn't have the necessary permissions or the correct path is not set. The root cause can often stem from two primary issues:

File Execution Permissions: The system may block the execution of the created file due to insufficient permissions.

Incorrect File Path: The specified command might be pointing to the wrong executable file.

The Solution: Execute the Correct Kotlin File

After investigating the issue, the solution is surprisingly straightforward. The executable you need to call is not the direct Kotlin compiler, but instead the batch file that wraps it. Here’s how you can do that.

Step 1: Update Your Rust Code

First, you need to locate the correct path to the Kotlin compiler. As found in this solution, the correct command to run from Rust should be:

Key Changes to Note

File Path: Ensure that you're using the complete path to the Kotlin batch file located in the bin directory.

File Extension: On Windows, you should call the .bat file to execute Kotlin scripts.

Step 2: Compile and Run

After making the modifications, compile your Rust application and run it again. This should effectively resolve any permission issues and execute the Kotlin scripts as intended.

Step 3: Verify the Output

Once the command runs successfully, you can check the output or the script's results in your terminal or console. If set up correctly, you should see the expected results without encountering the previous permission errors.

Conclusion

Dealing with cross-language execution can sometimes be confusing due to environment differences and file path issues. By ensuring you target the correct batch file for executing Kotlin from Rust and adjusting your code accordingly, you can bypass the access denied errors on Windows seamlessly.
