在IntelliJ插件中创建后台任务 [英] Create a background task in IntelliJ plugin

问题描述

我正在开发一个IntelliJ-idea插件，并希望在后台任务中运行代码（在后台任务对话框中和在UI之外的另一个线程中可见）。

I'm developing an IntelliJ-idea plugin and want to run code in background task (visible in the background tasks dialog and in another thread than the UI).

我找到了以下帮助程序类并通过传递尝试一个Runnable对象并实现其run方法，但它仍然阻止了UI，当我尝试自己进行线程处理时出现以下错误

I found the following Helper class and tried it by passing a Runnable object and implement its run method but it still blocking the UI and when I tried to do the threading myself i got the following error

 Read access is allowed from event dispatch thread or inside read-action only (see com.intellij.openapi.application.Application.runReadAction())
     Details: Current thread: Thread[Thread-69 [WriteAccessToken],6,Idea Thread Group] 532224832
     Our dispatch thread:Thread[AWT-EventQueue-1 12.1.4#IU-129.713, eap:false,6,Idea Thread Group] 324031064
     SystemEventQueueThread: Thread[AWT-EventQueue-1 12.1.4#IU-129.713, eap:false,6,Idea Thread Group] 324031064

推荐答案

我找到了一个更好的方法来运行流程作为后台任务和你更新进度条百分比和文本

I have found a better way which run the process as background task and you update the progress bar percentage and text

ProgressManager.getInstance().run(new Task.Backgroundable(project, "Title"){
        public void run(@NotNull ProgressIndicator progressIndicator) {

            // start your process

            // Set the progress bar percentage and text
            progressIndicator.setFraction(0.10);
            progressIndicator.setText("90% to finish");


            // 50% done
            progressIndicator.setFraction(0.50);
            progressIndicator.setText("50% to finish");


            // Finished
            progressIndicator.setFraction(1.0);
            progressIndicator.setText("finished");

        }});

如果您需要从其他线程中读取一些数据，您应该使用

If you need read some data from other thread you should use

AccessToken token = null;
try {
   token = ApplicationManager.getApplication().acquireReadActionLock();
                    //do what you need
} finally {
   token.finish();
}
