IntelliJ Gradle Memory Usage 关注

I have a gradle project in IntelliJ. If I build the project, a Java application occurs with 3 GB memory in the background. After build, this java app stays in background. I do not run the application. Why is this Java app runs and why it use a lot of memory?

I kill the Java app but it appears after gradle build. Sometimes two java app appears.

After I run the application, really application Java runs with 800 MB memory. I do not have a lot of memory and I do not want to this 3 gb Java app for gradle build. How can I prevent occuring that?

I use Intellij Ultimate 2021.3.2 in Windows 10 Pro 21H1 19043.928.

These are settings:
