Here are the highlights of this release:

• Control which dependencies can be retrieved from which repositories
• Production-ready configuration avoidance APIs

Hi,
the MuCats build depends on a MuWire build (https://github.com/zlatinb/muwire) you need to execute gradlew clean publish in the MuWire source tree. That will make the com.muwire.core artifact available to MuCats.

Thank you for your brilliant work, zlatinb.

JDK is needed, not just JRE.
Trying again resulted in the following error message.
I think packaging applications is important for uniform bug feedback. For example, creating an AppImage might help on GNU+Linux and maybe something like Zero Install for other platforms:
http://0install.net/

gradlew clean publish

FAILURE: Build failed with an exception.

* What went wrong:
Could not initialize class org.codehaus.groovy.runtime.InvokerHelper

* 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.

I've seen that error when trying to build with newer JDKs (14+). But the gradlew clean publish task should work fine with JDK 8 to 11. Depending on your operating system there may be different ways of switching between JDK versions; the one that I use is setting the JAVA_HOME variable to point to the deployment of the JDK. Also make sure you point to the specific gradlew script included in the source tree, i.e don't forget the ./

I already provide an AppImage for MuWire for Linux x86-64, armhf and aarch64 architectures. It is available for download from https://muwire.com .

The MuCats project is intended for more technical users who would not mind to modify the source code for their specific needs, so I haven't put much effort into packaging it.
