How to export EMF projects and Sirius as plug-ins using Maven and Tycho?
Hope to give a tutorial
Thank you.

I don't know much about Maven and Tycho. I hope a kind-hearted person can make a tutorial video about "How to export EMF projects and Sirius as plug-ins using Maven and Tycho?"

This "How to create an Eclipse Sirius based RCP" video is a great place to start:

https://www.youtube.com/watch?v=ZmUrTlzqCXc

It may not directly answer all of your questions, but it's a nice, step by step, from beginning to end overview. It really helped understand stuff I was missing.

So watch this video and try it yourself. Once complete, you'll know a lot more about how Tycho bridges between the Eclipse plug-in world and the Maven world.

I tried, and the RCP has been successfully built, but the log reports the following errors

index.php/fa/41565/0/

Sometimes a built product may be missing plugins that are only discovered at runtime. To debug this, you need to track that you are sure the missing plugin is discoverable within your target, your feature, and finally make sure it's mentioned in your product.
Your Maven build is following a different set of "build instructions" than the Eclipse IDE (Tycho is playing a part in translating your Eclipse project META-INF stuff to Maven). And your eclipse-product specifies which features/plugins get bundled together with the final product.
I would first start at your product description make make sure you've included that feature/plugin into the product definition. (this is frequently where I've hit missing plugins at runtime)

You can examine the plugins of your product. With the video I linked, I believe your product will be a zip file for windows/etc (yours looks like Windows) . If you open that zip file, you can look into the plugins included and make sure the missing plugin mentioned in your error exists
in the product that got created. 7-Zip lets you browse the export *.zip file.

I was following along with the video tutorial that you posted and now I have the following tycho errors after converting my metamodel project to a maven project:
index.php/fa/41645/0/

Any idea how to resolve these errors?

This is the pom.xml file for the project:

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">
  <modelVersion>4.0.0</modelVersion>
  <groupId>org.mcmaster.workflowplus.wfp</groupId>
  <artifactId>org.mcmaster.workflowplus.wfp</artifactId>
  <packaging>eclipse-plugin</packaging> <!-- This is the line causing the error in the pom.xml file for my metamodel project that was converted to maven.-->
  <name>Workflowplus</name>
  <parent>
  	<groupId>org.mcmaster.workflowplus</groupId>
  	<artifactId>org.mcmaster.workflowplus.parent</artifactId>
  	<version>0.0.1-SNAPSHOT</version>
  	<relativePath>../../../../../eclipse-workspace/org.mcmaster.workflowplus.parent</relativePath>
  </parent>
</project>

I've managed to resolve those errors however I am also running into a similar issue with my dependencies.
index.php/fa/41659/0/

Those are the messages I receive when I run as Maven Install. However what I am confused about is that Sirius 6.4.2 is already in my project manifest.mf
index.php/fa/41660/0/

I am unsure how to resolve this issue. Any advice?

With the Sirius entry inside your manifest file, you need to double check that particular version of Sirius is in the eclipse target plugin for your app.

It very likely is not.

Your target is an independent specification of all plugins independent from your eclipse install you're using to develop in. This lets you define a minimum set of plugins for your app instead of a potentially bloated development environment.
