This short article illustrates reasons for switching to IntelliJ IDEA as an alternative IDE for writing Scala as opposed to using Eclipse. We also show how to do the setup. IntelliJ IDEA is a Java IDE from JetBrains, which supports Scala. IntelliJ’s youtube channel contains more material and guides for those who are interested.
Reasons to Use IntelliJ
Here are some reasons why I use IntelliJ.
- It’s easy and intuitive to learn for people of any skill level.
- It has a user-friendly and sophisticated interface.
- It has an option to choose a dark theme, such as Darcula, which is much more pleasant for the eyes, especially later in the evening.
- It uses Source Code Pro font by default, which is font designed for programming.
- It has powerful refactoring and static code analysis tools.
- It is intended to be used with the keyboard and doesn’t require a lot of mouse movement.
Setting Up IntelliJ IDEA

- Optional: Set theme to Darcula.
- Linux users: Make desktop entry, by searching from settings create desktop entry.
Importing a Project
In this section, we show how to import a project for the Aalto University Scala programming courses. We use the CS-A1140 Data Structures and Algorithms course files as an example.
