Interoperability among Jason, Cartago, and C4Jason

[gciatto]

I need to use Cartago + Jason. Similarly to what discussed here, I need to create a self-configuring Gradle project.

I set my dependencies as follows:

dependencies {
    implementation("org.jason-lang", "jason", "2.5-SNAPSHOT")
    implementation("org.jacamo", "cartago", "2.5")
    implementation("org.jacamo", "c4jason", "2.0.2")
}

and my repositories as follows:

repositories {
    maven("http://jacamo.sourceforge.net/maven2")
    maven("https://jade.tilab.com/maven")
    mavenCentral()
}

My mas2j file is as simple as the following one:

MAS helloworld {
  infrastructure: Centralised
  environment: c4jason.CartagoEnvironment
  agents: hello_agent agentArchClass c4jason.CAgentArch;
  aslSourcePath: "src/main/asl";
}

so I barely exploit a CartagoEnvironment, and my hello_agent.asl is as follows:

!hello.

+!hello : true
  <- .my_name(Name);
     println("Hello, world! by ",Name).

However, if launch the MAS, get the following error: After a bit of debugging, I figured out that c4jason is looking for the cartago.security.AgentCredential class which has been moved to cargago.AgentCredential somewhere before cartago:2.0.2 (which is the earilest one available on http://jacamo.sourceforge.net/maven2). So there is no version of cartago on that repository which seems to be compatible with c4jason:2.0.2, and only that version of c4jason is available on that repository. (Here, by "compatible with" I mean "having a class named cartago.security.AgentCredential").

So, I tried with the following dependencies:

dependencies {
    implementation("org.jason-lang", "jason", "2.5-SNAPSHOT")
    implementation("org.jacamo", "cartago", "2.5")
    implementation("org.jacamo", "jaca", "2.5")
}

but this time I get the following error: and I was not able to figure out why.

So my question here is: which set of artifacts should I use to ley my project exploit Cartago from Jason? And which versions of those?

i would be interested in this feature as well

The integration of Jason and Cartago is not well supported indeed.

I can try to figure out the problem, but... I'd suggest you to use JaCaMo instead, it aims to properly integrate jason and cartago. In the case of cartago 2.5, the jacamo 0.10 should be used.

@jomifred thanks for the hint. I tried with the following dependencies:

dependencies {
    implementation("org.jacamo", "jacamo", "1.0-SNAPSHOT")
}

The second message error is apparently still there:

I don't know what to do.

[jomifred]

In the case of Jason+Cartago (no JaCaMo), the cartago package was renamed from c4 to jaca, I guess that is the main issue.

I committed and example (using gradle) at https://github.com/jason-lang/jason/tree/hotfix/demos/basic-cartago

Notice that it uses RunCentralisedMAS (I still do not fix the it for RunJasonProject).

[robertacalegari]

Thank you so much @jomifred, I manage to run the gradle project with jaca!

[gciatto]

Apparently, @robertacalegari retried with:

dependencies {
    implementation("org.jason-lang", "jason", "2.5-SNAPSHOT")
    implementation("org.jacamo","cartago", "2.5")
    implementation("org.jacamo", "jaca", "2.5")
}

and it works now. Did you, @jomifred, changed something in any of the artifacts? Otherwise, I may have mistaken some test of mine. In that case, I apologise.

[jomifred]

I didn't change cartago. I guess the issue is to use c4jason instead of jaca.... (I am not a great expert about cartago, sorry)
