GitHub Copilot for Eclipse

v0.21.0 (build 20261009)

【中文】

因微软原版插件对本地大模型的支持不是太友好，仅仅ollama可用，而ollama又很鸡肋，故为支持更多本地大模型的使用，特此在微软开源基础上扩展了本地支持。

• 00_Diff - 本地变更对应的代码变更差分

本地大模型的添加方式：

• 登录 GitHub → Preferences → GitHub Copilot → Model Management → Add Provider... 添加你的本地 OpenAI 兼容端点
• 选择你刚添加的本地 OpenAI 兼容端点后→ Add Model... 添加你的本地大模型信息

手动编译完整步骤：

# 1. 拉取语言服务器二进制（必须，约1-2分钟；-f 不能省，
#    因为 package.json 声明了 5 个平台的包，不加 -f 会报 EBADPLATFORM）
cd com.microsoft.copilot.eclipse.core\copilot-agent
npm i -f

# 2. 回根目录完整打包（约8分钟）
cd ..\..
.\mvnw.cmd clean package

产物：

• 可安装 zip： com.microsoft.copilot.eclipse.repository\target\com.microsoft.copilot.eclipse.repository-0.21.0-SNAPSHOT.zip （~500MB，含 5 平台语言服务器）
• Eclipse 里 Install New Software → Add → Archive 选这个 zip 即可

环境要求：JDK 17+、Node.js、Maven 用自带的 mvnw.cmd 即可。

【English】

Because Microsoft's original plugin has limited support for local LLMs — only Ollama is supported, and Ollama is quite limited in usefulness — this project extends the Microsoft open-source plugin to support more local LLMs.

• 00_Diff - Code diff for the local changes

How to add a local LLM:

• Sign in to GitHub → Preferences → GitHub Copilot → Model Management → Add Provider... and add your local OpenAI-compatible endpoint
• After selecting the local OpenAI-compatible endpoint you just added, click Add Model... and add your local LLM information

Full manual build steps:

# 1. Fetch the language server binaries (required, ~1-2 minutes; do not omit -f,
#    because package.json declares packages for 5 platforms; without -f it fails with EBADPLATFORM)
cd com.microsoft.copilot.eclipse.core\copilot-agent
npm i -f

# 2. Go back to the repo root and do a full package build (~8 minutes)
cd ..\..
.\mvnw.cmd clean package

Artifacts:

• Installable zip: com.microsoft.copilot.eclipse.repository\target\com.microsoft.copilot.eclipse.repository-0.21.0-SNAPSHOT.zip (~500MB, includes language servers for 5 platforms)
• In Eclipse, use Install New Software → Add → Archive and select this zip

Requirements: JDK 17+, Node.js, and Maven via the bundled mvnw.cmd.

GitHub Copilot for Eclipse

GitHub Copilot for Eclipse brings AI-assisted coding to the Eclipse IDE with these core capabilities:

• Code completions for in-editor suggestions from code context or natural-language comments.
• Next Edit Suggestions provide context-aware suggestions for your next code edits.
• Agent Mode for conversational help and more autonomous, project-aware assistance.
• Model Context Protocol (MCP) integration to connect Copilot with external tools and services.
• Advanced Agentic Capabilities include Custom Agents, Isolated Subagents, and Plan Agent, with more agentic capabilities coming soon.

Usage-based billing support

Starting from version 0.18.0, we have added internal support for the upcoming usage-based billing experience, including experience updates to the usage panel, usage notifications, and model picker. These changes will become visible once usage-based billing is rolled out.

To ensure compatibility with the new billing experience, we strongly recommend upgrading the plugin to 0.18.0 or later as soon as possible.

Clients using older plugin versions will continue to function. However, the billing and usage experience may not be optimal and may not accurately reflect the latest usage-based billing experience.

Core capabilities

Code completions

Inline suggestions (ghost text) appear as you type in the editor. Suggestions can range from small edits to multi-line changes.

Next Edit Suggestions

Next Edit Suggestions predict your next edit location and propose the next change based on your recent edits and context.

Agent and Ask Mode

Ask Mode provides conversational AI assistance for explaining code, generating code from requirements, suggesting refactors, and providing debugging guidance.

Agent Mode works autonomously across your project context to identify and fix issues, propose implementation steps, and support larger coding tasks with iterative guidance.

Model Context Protocol (MCP)

MCP support enables integrating external tools and services into Copilot workflows where configured.

Advanced Agentic Capabilities

• Custom Agents allow users to create personalized agents with specific instructions and behaviors.

• Isolated Subagents can be spawned by the main agent to handle specific tasks or contexts independently.

• Plan Agent can generate multi-step plans to accomplish complex tasks, breaking them down into manageable actions.

• Skills are reusable, specialized AI assistant templates that enrich chat context in Agent Mode. Skills are defined as SKILL.md files and can be scoped to a workspace or shared globally.

  • Creating Skills

    Place a SKILL.md file in any of these directories:

    • Project-scoped: .github/skills/<skill-name>/, .claude/skills/<skill-name>/, .agents/skills/<skill-name>/
    • User-scoped (global): ~/.copilot/skills/<skill-name>/, ~/.claude/skills/<skill-name>/, ~/.agents/skills/<skill-name>/

    Each SKILL.md file can include YAML front matter with metadata (name, description) followed by Markdown content that provides domain knowledge, workflows, or instructions for the AI assistant.

    Skills are automatically discovered and available in Agent Mode. You can enable or disable skills in Window → Preferences → Copilot → Chat → Enable Skills.
