I was trying to run a Java application when I got this error:

# ./gradlew run

FAILURE: Build failed with an exception.

* What went wrong:
Could not determine java version from '11.0.5'.

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.
root@ubuntu-512mb-sfo1-01:~/KOMORANRestAPIServer# cat build.gradle

Posts on StackOverflow suggest many things like updating Gradle with this command ./gradlew wrapper --gradle-version 6.0.1. But running it gives the same error:

# ./gradlew wrapper --gradle-version 6.0.1


FAILURE: Build failed with an exception.

* What went wrong:
Could not determine java version from '11.0.5'.

I had to manually change the version in gradle/wrapper/gradle-wrapper.properties. Once I did, Gradle ran correctly:

# ./gradlew run
