How to package a dependency

Camel K supports Jitpack to allow packaging your local code into a running Integration. The operator will recognize the major git repositories and provide all the needed configuration to package the dependency and locally install into Camel K artifacts repository. As an example, we can use a sample jitpack project, which contains some developments on main branch, a final release tagged as v1.0 and other developments ongoing on 1.0.0 branch.

Within your route, you can import the code as you'd normally do with any other library:

import org.apache.camel.builder.RouteBuilder;
import acme.App;

public class Jitpack extends RouteBuilder {
  @Override
  public void configure() throws Exception {
      from("timer:tick?period=2000")
        .setBody()
          .simple(App.capitalize("hello"))
        .to("log:info");

  }
}

Once done, you must just reference the project in kamel run -d option, ie -d github:squakez/samplejp.

Package the default branch (main)

You can choose to use the default dependency without specifying a tag or branch, that will fetch the source code on main branch:

kamel run Jitpack.java --dev -d github:squakez/samplejp

...

Package another branch (1.0.0)

You can choose to compile the source code stored on a given branch, ie, on 1.0.0 branch:

kamel run Jitpack.java --dev -d github:squakez/samplejp:1.0.0-SNAPSHOT

...

Package a fixed release tagged

You can also choose to package the source code released with a tag, ie v1.0:

kamel run Jitpack.java --dev -d github:squakez/samplejp:v1.0
