This is a Kotlin bug, you can vote and watch it for updates: https://youtrack.jetbrains.com/issue/KT-36253. A workaround is to kill the running Java processes.
I have this problem almost every build (Android Studio stable + Artic Fox).
Manual Solution (try this first, if it works continue)
Task manager > Processes > End "OpenJDK Platform Library" tasks (sometimes it's standalone, sometimes it's under "Android Studio")
OR
Task manager > Details > End "java.exe" tasks
Automated Solution
- Create a new end-java.bat file
- Content of .bat file:
taskkill /f /IM java.exe - Right click end-java.bat file > create shortcut
- Right click the shortcut > properties
- Add shortcut key (e.g. ALT + CTRL + 1)
- ALT + CTRL + 1 will now fix the issue
Try This :
https://developer.android.com/studio/build/build-cache
Add this code :
// To re-enable the build cache, either delete the following
// line or set the property to 'true'.
android.enableBuildCache=false
After that clean project and restart android studio
Also you can try to use a different JDK (e.g. OpenJDK). It helped me.
File -> Project Structure -> SDK Locations -> JDK Location
You can reboot the system, it will help. But this problem will return soon. This is the bag of Android Studio 4.2 https://youtrack.jetbrains.com/issue/KT-36253
