The Mysterious Case of IntelliJ Scala 2.13.0: Solving the “Error compiling the sbt component ‘compiler-bridge-2.13.0-66.0′” Conundrum

Are you an intrepid developer who’s ventured into the realm of Scala programming, only to be thwarted by the ominous “Error compiling the sbt component ‘compiler-bridge-2.13.0-66.0′” message in IntelliJ? Fear not, dear reader, for we’re about to embark on a thrilling adventure to vanquish this error and get your Scala project up and running smoothly.

The Problem: A Brief Introduction

The error message in question is often encountered when attempting to compile a Scala project in IntelliJ, specifically when using Scala version 2.13.0. This version, released in 2020, brought about significant changes to the Scala compiler, which can sometimes lead to compatibility issues with the sbt compiler bridge.

The Culprits: Scala 2.13.0 and the sbt Compiler Bridge

The Scala 2.13.0 release introduced several notable changes, including:

• Improved performance and memory usage
• Enhanced type inference and error reporting
• Support for Java 11 and later

While these changes are undoubtedly exciting, they can also lead to incompatibility issues with the sbt compiler bridge. The sbt compiler bridge is a crucial component that enables sbt (Simple Build Tool) to interact with the Scala compiler. When this bridge fails to compile, the entire build process comes to a grinding halt.

The Solution: A Step-by-Step Guide

Fear not, dear reader, for we’ve got a comprehensive step-by-step guide to help you overcome this hurdle.

Step 1: Update Your Scala Plugin

First things first, ensure you’re running the latest version of the Scala plugin for IntelliJ. To do this:

2. Click on Plugins in the left-hand menu
3. Search for “Scala” in the marketplace
4. Update the Scala plugin to the latest version

Step 2: Check Your Scala Version

Verify that you’re using Scala version 2.13.0. To do this:

1. Open your build.sbt file
2. Check the Scala version specified in the file. It should resemble the following:

   <scalaVersion>2.13.0</scalaVersion>

Step 3: Update Your sbt Version

Update your sbt version to the latest release. You can do this by:

1. Opening your build.sbt file
2. Updating the sbt version to the latest release. For example:

   sbt.version = "1.4.9"

Step 4: Clean and Reload Your Project

Clean and reload your project to ensure that IntelliJ picks up the changes:

1. Open the Terminal in IntelliJ

Step 5: Invalidate Caches and Restart IntelliJ

Invalidate IntelliJ’s caches and restart the IDE to ensure that everything is properly reloaded:

1. Open the File menu
2. Click on Invalidate Caches/Restart

The Fix: Compiler Bridge Configuration

Now that we’ve updated our Scala plugin, Scala version, sbt version, and cleaned and reloaded our project, it’s time to configure the compiler bridge.

Step 1: Create a New Compiler Bridge Configuration

Create a new compiler bridge configuration by:

1. Opening the Settings (or Preferences on Mac)
2. Navigating to Languages & Frameworks > Scala > Compiler
3. Clicking on the + button next to Compiler Bridges
4. Selecting Scala 2.13.0 from the dropdown menu
5. Clicking Apply and then OK

Step 2: Configure the Compiler Bridge

Configure the compiler bridge by:

1. Opening the build.sbt file
2. Adding the following configuration:

     scalaOrganization := "org.scala-lang",
     scalaVersion := "2.13.0",
     scalacOptions += "-Ywarn-unused"
     

The Verdict: A Successful Compilation

And that’s it! With these steps, you should now be able to compile your Scala project successfully. If you encounter any further issues, ensure that you’ve updated all dependencies and plugins accordingly.
