Solution Description

AssistAI is an Eclipse IDE plugin that brings AI assistant into your development environment. 

Features

  1. Refactor selected code snippets with LLM
  2. Generate JavaDoc comments for chosen classes or methods with LLM's help
  3. Create JUnit tests for selected classes or methods using LLM's assistance
  4. Engage in a conversation with LLM about the content of the currently opened file
  5. Fix compilation errors with LLM's guidance
  6. Copy code blocks generated by LLM to the clipboard
  7. Produce Git commit comments based on changes in staged files
  8. Customize pre-defined prompts
  9. Using the built in tools (MPC) AssistAI can:
    1. use JavaDoc or related source code to better understand the context
    2. perform a web search using DuckDuckGo
    3. read a content of a web page
  10. Create contexts for the LLM that include source files or images
  11. Use the vision model to discuss a image content
  12. Switch between defined LLMs
  13. [NEW] Added support for interfacing with Model Context Protocol (MPC) servers. The plugin is a MCP Client. You can interface your favorite MCP servers using any of the supported LLMs (not limited to Claude).
  14. [NEW] Now you can give control to LLM to modify your project files, access error logs, console output, and more... use Claude, sit back, vibe, and watch them tokens burn
  15. [NEW] Discuss about math, or tabular data. The chat component now supports latex and table rendering
  16. [NEW] Added tools that AI agents can use to execute and review JUnit tests and execute maven builds
  17. You can also pose general questions to LLM, just like with the regular AI chatbot interface.

Note: This plugin requires access to an LLM (e.g. OpenAI, Claude, or LM Studio running locally). You may need an API key to work. Depending on your LLM provider charges for API usage may apply.

I installed AssistAI Plugin in eclipse 2024-03 / 2020-03 version, but after installation successfully, no AssistAI Preferences menu on any toolbars. On marketplace tab > installed, I can find AssistAI installed successfully. 

 I spend a lot of time for (re-)installation & uninstallation for testing. Please help for this. Thank you.

I have installed the plugin & configured the AssistAI (Chapt-GPT) in Eclipse IDE. I also have API Key setup. Written a simple "Hello World" program. Selected the code & right click - Assist AI (which has Discuss, Refactor, Document etc). When asked ChatGPT to Discuss, Refactor etc, there is NO Response.. Its blank. 

Do I need to do any further setup or why is it not responding ? Please help me.

Tried all the options from the file menu (Assist AI) but the ChatGPT view never got opened automatically if it is not opened before. Thereafter, tried to chat with the agent but no response has been returned, whereas the API key works perfectly (tried using CURL).

Hi,

After selecting a piece of code, I selected the -Discuss option, as well as the other options, and gave the prompt, but no response.

Could you please help me with this issue?


I would like to attach a screenshot but I don't see the option.

Thanks,

Marius

I installed the plugin, and and accepted the license, it all looks fine, I see it listed as installed software... but there is no menu item for it to be configured with, nor is there any window to add to my display... literally, it is like I never installed it.  Have restarted the IDE and uninstalled/reinstalled, no luck.  Any help greatly appreciated, thanks.

Hi,

I installed the plug-in in my Eclipse IDE (2022-09 version). However, upon installation (including IDE restart), nothing happened. My IDE tells me it is installed, but I have no idea how to activate and use it. Where or what do I click to make it "start"? Like there is no AI window or anything showing different in my Eclipse that is popping up for me to use. Please help! (I read the description of it being tested with 2022-03, but still.)

After installing the plugin, configure access to the OpenAI API:

Open Window > Preferences > Assist AI preferences

Input your OpenAI API key (you can find your keys at https://platform.openai.com/account/api-keys)

Input the model name. By default, the plugin uses the gpt-4 model, but you can also utilize gpt-3.5-turbo or any available ChatGPT model. To check which models are available to you, go to https://platform.openai.com/playground?mode=chat and check the Model drop list.

Hello Sir,

I feel like this is related to Chat GPT API key error. Can you assist me with where do I need to enter the API key on my already installed plugin?

Hoping for a prompt response ,

Thanks,
