How to Build a Self‑Discipline IntelliJ Plugin to Stop Coding Fatigue

This article describes the StopCoding IntelliJ plugin, created to remind developers to take breaks and avoid prolonged sitting while coding.

Installation Guide

1. Search for and install the StopCoding plugin directly in IDEA (officially approved).

2. For internal networks, download the plugin from GitHub and install it locally.

Local installation steps are shown in the following screenshot.

Usage

Step1: Open the plugin via Tools → StopCoding .

Step2: Configure the desired parameters and save.

Step3: Continue coding; the plugin will display an unclosable reminder dialog with a countdown after the set interval, forcing a break.

Development Tutorial

The plugin is simple and built with basic Java knowledge. Its structure includes:

plugin.xml – core configuration file.

data package – contains SettingData model and DataCenter static variables.

service package – TimerService implements the timing logic.

task package – RestTask and WorkTask handle break and work periods.

ui package – SettingDialog and TipsDialog provide the configuration and reminder dialogs.

StopCodingSettingAction – entry action for the plugin.

Swing UI

IDEA makes creating Swing dialogs straightforward; the article shows how to create dialogs and bind button events.

Code Example

public class TestDialog extends JDialog {
    private JPanel contentPane;
    private JButton buttonOK;
    private JButton buttonCancel;

    public TestDialog() {
        setContentPane(contentPane);
        setModal(true);
        getRootPane().setDefaultButton(buttonOK);

        buttonOK.addActionListener(e -> onOK()); // OK button listener
        buttonCancel.addActionListener(e -> onCancel()); // Cancel button listener
        // other code
    }
}

Timer

The plugin uses java.util.Timer to schedule work and break intervals, employing schedule to add tasks and cancel to stop the timer.

Conclusion

With this overview, readers can explore the source code and try building their own IDEA plugin to encourage regular breaks and improve health while coding.
