I'm looking for "slim3-gen-jsr269.jar".

[mnakai]

I searched for this but it exists. https://mvnrepository.com/artifact/org.slim3/slim3-gen

I thought there was a source file on this site and tried running the command.
$ mvn archetype:generate -DarchetypeCatalog=http://slim3.github.com/slim3/archetype-catalog.xml

I wondered if it would be created when I run this mvn command, but I get an error.😫

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-archetype-plugin:3.2.1:generate (default-cli) on project slim3-root: archetypeCatalog 'http://slim3.github.com/slim3/archetype-catalog.xml' is not supported anymore. Please read the plugin documentation for details.

I want to verify the operation of an old program with java8, but I'm stuck because I don't have "slim3-gen-jsr269.jar".
Could you tell me how to build it?
