When compiling Kotlin example with Gradle 6, the following error appears. Note the "What went wrong" section. {noformat} $ gradle build Starting a Gradle Daemon, 1 incompatible and 1 stopped Daemons could not be reused, use --status for details > Task :buildSrc:spotlessGroovy FAILED FAILURE: Build failed with an exception. * What went wrong: Execution failed for task ':buildSrc:spotlessGroovy'. > You must declare outputs or use `TaskOutputs.upToDateWhen()` when using the > incremental task API * Try: Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights. * Get more help at https://help.gradle.org Deprecated Gradle features were used in this build, making it incompatible with Gradle 7.0. Use '--warning-mode all' to show the individual deprecation warnings. See https://docs.gradle.org/6.2.2/userguide/command_line_interface.html#sec:command_line_warnings BUILD FAILED in 4s {noformat} The cause is likely outdated version of spotless. [This GitHub issue|https://github.com/diffplug/spotless/issues/440] mentions the exact same error. P.S. I chose _examples-java_ as this Jira issue's component because _examples-kotlin_ is not an option. -- This message was sent by Atlassian Jira (v8.3.4#803005)
