Dotenv: Apply .env to Eclipse Run Configurations

An Eclipse plugin that reads a .env file from the selected project and applies its key/value pairs to Java Application Run Configurations for the selected project.(Environment variables).

Features

• Right-click a project in Project Explorer
  • Environment Variables → Apply .env to Run Configurations
• Adds variables to the launch configuration’s Environment map
• Does not auto-apply on Run/Debug (manual action by design)

How it works

• Looks for .env in the selected project root
• Parses lines in dotenv style:
  • KEY=VALUE
  • ignores blank lines and # comments

Installation (from update site)

1. Help → Install New Software…
2. Add… → select the update site

• Update site: https://ankitx-sharma.github.io/Dotenv_eclipse-env-variable/updates/

3. If you see “No categorized items”, uncheck:
   • ✅ Group items by category
4. Install and restart Eclipse

Usage

1. Create a .env file in your project root
2. Create (or run once) a Java Run Configuration for your app
3. Right-click the project:
   • Environment Variables → Apply .env to Run Configurations
4. Verify in:
   • Run Configurations… → (your app) → Environment

Future Development Plan

• Support multiple files (e.g. .env.local, .env.dev)
• Better conflict handling (e.g. “override existing” toggle)

Compatibility

• Tested with Eclipse 2026-03 (4.39) and Java projects.
