expo opt-in-google-play-signing PEPK tool failed

Hi all

I’m trying to run expo opt-in-google-play-signing
After i enter ‘n’ and then my encryption key, I get the error message:
Error: PEPK tool failed with return code Error: File not found:

But it does not mention any file that is not found.

I’m on node version v10.16.2
expo cli version 3.0.9
expo version 34
Windows 10 using the powershell / command line

Thanks

There is no java in your PATH.

java -jar ... command is failing
