Current setup
Looking for a Codename One download?
Current Codename One projects use Maven, so there is no separate IDE plugin to install. Generate a project and open it in IntelliJ IDEA, NetBeans, Eclipse, VS Code, or another Maven-capable IDE.
If an older IDE plugin or archived link sent you here, use the migration path below.
- New projects use one Maven structure across supported IDEs.
- You no longer need the legacy NetBeans, IntelliJ IDEA, or Eclipse plugin to create a project.
- Existing Ant-based Codename One projects can be migrated to Maven.
Generate
Create a Maven project with Initializr.
Choose Java, enter the project names, and download the generated project. Open its root directory in your IDE and run the included simulator target.
Keep your source
Move an older Ant project to Maven.
The migration tool generates the current Maven project structure from an existing Codename One application or library project. Review the migration steps before changing the original project.
