Changes

[23.Aug.2021]

Gradle wrapper version upgraded from version 6.x to 7.0

This will change the version in wrapper.settings

 ./gradlew wrapper --gradle-version 7.0

This will update the complete wrapper and download version 7.0 jar

 ./gradlew wrapper --gradle-version 7.0

In build.gradle file, replace:

• compile with implementation
• testCompile with testImplementation

Because, version 7.0 removed compile and testCompile configurations. Source: https://docs.gradle.org/current/userguide/upgrading_version_6.html#sec:configuration_removal
