Eclipse IDE for Java Developers ou IntelliJ IDEA : une bonne alternative sous Linux ?

Eclipse IDE for Java Developers, alternative Linux à IntelliJ IDEA

Mis à jour le 21 octobre 2026

Notre avis

Eclipse is a solid, free alternative for developers who prioritize standard Java and enterprise tooling over modern Kotlin-first workflows. It handles large codebases well with its mature refactoring tools and integrated Git client. However, if your project relies heavily on Kotlin, you will struggle because Eclipse's Kotlin support is a third-party plugin, not a first-class citizen like in IntelliJ. For pure Java development, Eclipse is a viable, cost-effective choice. For mixed Java/Kotlin teams, it is a significant step down in developer experience.

Ouvrir vos fichiers IntelliJ IDEA

Eclipse cannot directly open IntelliJ IDEA project files (.idea folder, .iml files). You must recreate the project structure in Eclipse by importing the source code and build files (pom.xml or build.gradle). The .classpath and .project files generated by Eclipse are specific to its workspace and are not compatible with IntelliJ. You will need to configure your build tools manually in Eclipse to match your existing setup.

Is Eclipse free for commercial use?

Yes, Eclipse is free and open-source under the EPL-2.0 license, making it suitable for both personal and commercial use without licensing fees.

Can I use the same plugins in Eclipse and IntelliJ?
