Gitlab CI/CD Build Issue

[worldstarHQH]

Building an android project using gitlab ci/cd.
There is no problem in the build process, but after the build is completed, the java.exe process is not terminated, so the build stage does not move on to the next stage.
My solution is terminate java.exe process directly.
Is there any way to solve this problem?

android studio : 3.6.3
gradle : 5.6.4
openjdk : 11.0.2.0

thanks
