   Open-source IntelliJ IDEA: A Simpler Way to Build and Contribute to the Community

   JetBrains has simplified building and contributing to IntelliJ IDEA's open-source codebase by introducing CI/CD pipelines via GitHub Actions and publishing ready-to-use open-source builds directly on GitHub. Developers can now fork the repository and build their own version of the IDE without manual environment configuration. The open-source codebase powers not only IntelliJ IDEA but also Android Studio and other development tools, making it easier for the community to explore, customize, and contribute to the platform.

   IntelliJ Platform 2025.3: What Plugin Developers Should Know

   IntelliJ Platform 2025.3 introduces a unified distribution merging Community and Ultimate editions while maintaining backward compatibility with plugins built for 2025.2 and earlier. Plugin developers targeting 2025.3 must update to IntelliJ Platform Gradle Plugin 2.10.4 and switch from intellijIdeaCommunity() to intellijIdea() dependency helper. Key changes include module extraction requiring explicit dependencies, IntelliLang plugin dependency updates, and Storage annotation restrictions. The unified distribution uses the IU product code, with feature access controlled by licensing rather than separate IDE distributions. Developers can test compatibility using the verifyPlugin task and EAP snapshots before the official release.
