I tried what is provided Gradle - Could not find or load main class but it did not help.

Any idea on how to fix this issue?

Migrate your gradle version to 6.1.1

gradle-wrapper.properties
distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
distributionUrl=https\://services.gradle.org/distributions/gradle-6.1.1-bin.zip
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
