Hello,

 

I trying to create minecraft mod that send ping to server every 1 second.

and I want to use ping wrapper library http://icmp4j.org/d/index.html for this mod, then I downloaded this and copy icmp4j.jar to `libs/icmp4j.jar` and `src/main/resources/META-INF/libraries/icmp4j-1.0.0.jar`.

 

It works well on runClient task, but builded jar file doesnt work.

I found out after read some docs this library was not registered to maven and I think it need to make `src/main/resources/META-INF/libraries/icmp4j-1.0.0.jar.meta` like this.

Maven-Artifact: org.icmp4j:icmp4j:1.0.0

 

finally, I added manifest attribute `ContainedDeps` to `build.gradle` like this

jar {
    manifest {
        attributes([
            "Specification-Title": "pingtoserver",
            "Specification-Vendor": "naari3",
            "Specification-Version": "1",
            "Implementation-Title": project.name,
            "Implementation-Version": "${version}",
            "Implementation-Vendor" :"naari3",
            "Implementation-Timestamp": new Date().format("yyyy-MM-dd'T'HH:mm:ssZ"),

            "ContainedDeps": "icmp4j-1.0.0.jar" // here
        ])
    }
}

 

but that doesnt work well (caused by same error at first)

 

here is my current sourcecode. https://github.com/naari3/PingToServer/tree/13bae40aae18cc9e0657826162a4c1ee4ac3ff28

 

any idea for this?

thanks.

Oh really, thank you for telling me that.

I hope it will be implemented
