New release won't install both on Linux and Windows 10

[ghost]

The installation fails on both Linux and Windows 10, I'm guessing due to the update to Diamant. Error message is the same:

Build file '.../dialogos-master/Diamant/build.gradle' line: 37

• What went wrong: A problem occurred evaluating project ':Diamant'.

  repository not found: .../Downloads/dialogos-master

• 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 5.0. Use '--warning-mode all' to show the individual deprecation warnings. See https://docs.gradle.org/4.10.2/userguide/command_line_interface.html#sec:command_line_warnings

I did not modify the files in any way after the download
