Run class from JAR with alias in catalog?

[axkr]

Is there a simple jbang catalog alias example, how to run an existing class from a JAR?

[maxandersen]

So not the main class?

Something like jbang alias add --name myalgias --main other.mainClass your.jar should work

[axkr]

I mean, how to specify (one of multiple) main classes which should be used and are not listed in the MANIFEST.MF of the JAR?

I tried this:

jbang org.matheclipse:matheclipse-io:2.0.0  --main=org.matheclipse.io.eval.MMAConsole

And if that works, whats best practice to define aliases for these main classes in a java jbang-catalog.json file?

[axkr]

Ok this approach works through a "redirect" in a Java file.

Is this best practice or can the mma alias be configured more "directly"?

@axkr with the answer @maxandersen gave you the "redirect" shouldn't be needed, right? You could run the alias and it would take care of specifying the correct main class.

Yes, using your example with my generic one:

jbang alias add --name mmaconsole --main=org.matheclipse.io.eval.MMAConsole org.matheclipse:matheclipse-io:2.0.0

Should give you something like this in your catalog:

"aliases": {
    "mmaconsole": {
      "script-ref": "org.matheclipse:matheclipse-io:2.0.0",
      "main": "org.matheclipse.io.eval.MMAConsole"
    }
  },

Thank you very much.

That works great:
