Arduino Eclipse Plugin

What Arduino Eclipse Plugin is
Arduino Eclipse Plugin, also called Sloeber, is an Eclipse-based IDE intended to help people develop Arduino projects and write, navigate, and understand code. The project says it retains the Arduino hardware and libraries users already use. Its editing features include context-sensitive coloring and search, and developers can control compile options and use multiple configurations. Sloeber also supports working with multiple projects in one environment, accessing Arduino core source and Arduino library code, and creating libraries.
The project runs on Windows, macOS, and Linux. Precompiled product packages and update sites are available through GitHub releases. Sloeber is free, and the project describes it as an open-source Arduino IDE alternative. Community help and issue reporting are available through links to GitHub discussions and reported issues. Building from source requires Java 17 and a 64-bit operating system, with Git and Maven listed as prerequisites. The project includes a topic for supported boards, but the stated information does not identify particular board models.
