12. Solutions for the failure of the last step of smart guide to generate source code (as shown in the figure below).

Reason one: Consider it is due to process occupation. You can try restarting IDEA. If generation still fails after restarting, you may need to try restarting the computer.
Reason two: If the above methods still do not solve the problem, go to FeiSuan JavaAI Advanced Settings ➡ Local Storage Path ➡ Delete the db file under this path, the path: /.feisuan/nlp/db, and then regenerate the source code.


13. After installing Feisuan JavaAI, the plugin cannot log in when opened?
Answer: Please troubleshoot and retry using the following methods:
- First, check if your computer has external network access. If not, you need to access through proxy settings. Open Advanced Settings, Configure Network Proxy, click for details.
- After setting up the network proxy on your computer, in Advanced Settings, under Network Proxy, select "Use System Network Proxy", then try logging in. If web login fails, choose to log in at the top of the IDE.
- If you still cannot log in after selecting "Use System Network Proxy", please select "Manually Configure Network Proxy", fill in the network proxy address, then log in via the IDE. IDE Login, click for details.

20. What kind of projects can the One-Click Fixer in the toolbox fix?
Answer: Currently, it only supports fixing Java projects. Projects in other languages cannot be fixed at this time.
21. What is the difference between Smart Answer and Agent? How should I choose?
Answer: Smart Answer provides reference solutions based on your task requirements, but it cannot take actual actions to solve the problem for you. The Agent, on the other hand, combines your task requirements with your current development project to generate the corresponding code or complete the task through actual execution. If you only need reference answers, using "Smart Answer" is more convenient. If you need actual task completion, the "Agent" will be of real practical help.
22. Can files generated, modified, or deleted in the workspace of a Smart Session be restored after acceptance?
Answer: Yes. In the workspace of a Smart Session, whether you have clicked "Accept" or "Reject" for generated files, you can restore them to their original state using the "Rollback" button on the workspace. Any changed code will also be reverted to its initial state.
23. What should I do if the source code generation process in Smart Guidance takes too long or gets stuck waiting?
Answer: Cancel and retry. On the final source code generation page of Smart Guidance, there is a "Cancel" button at the bottom. Click it and wait a moment for the cancellation to complete. Afterward, please select "Regenerate" or "Continue Generating" to try again.
24. The Smart Analysis button cannot be activated?
Answer: First, enable Smart Analysis by going to "Settings > Advanced Settings > Smart Analysis" and checking "Enable Smart Analysis". Then, click the Smart Analysis button to start the analysis. This analysis is project-level; for other open projects where Smart Analysis is not needed, you can simply click the button to turn it off without any adverse effects.
25. How to turn off the notification pop-ups in the bottom right corner?
Answer: Go to "Settings > Advanced Settings > Smart Settings Module" and uncheck "Enable Smart Notifications".
26. How to adjust the font size of the model's responses?
Answer: You can set the font size for replies in the Advanced Settings.
27. Does a single question usually trigger multiple automatic calls to the underlying model?
Answer: Yes, a single question from the user usually triggers multiple automatic calls to the underlying model, and each call counts toward your quota consumption.
- Simple Q&A: A single question typically triggers 5-20 model calls.
- Complex tasks: A single question typically triggers 20-50 or more model calls.
Note: The actual usage may vary depending on factors such as project complexity, codebase size, and whether "Deep Thinking" is enabled.
