Hi,
I wanted to debug/develop the coffee-editor in the eclipse ide.
I followed the steps mentioned in the readme:

Install Eclipse
Import projects from backend
- I did File > Import > Git > projects from Git > Clone URI > pasted https://github.com/eclipse-emfcloud/coffee-editor
Set target org.eclipse.emfcloud.coffee.target.target

After setting the targetplattform, eclipse shows me the following errors:


Description	Resource	Path	Location	Type

The project was not built since it depends on org.eclipse.emfcloud.coffee.workflow.generator.java, which has build path errors	org.eclipse.emfcloud.coffee.codegen.java.application		Unknown	Java Problem

When I try to start the model server via CoffeeModelServer.launch
the console is not updated but the server seems to work:
When goind to localhost:8081/api/v1/models I get:

type | "success"
-- | --
data | {}

Which indicates that it works.

But when I try something like the WorkflowAnalyzerServer:

and proceed I get:

An error has occurred. See the log file

Is there something else that has to be done?
If I build it with the run.sh script building succeeds and I can run the application.

Update:
Doing:

  cd backend/releng/org.eclipse.emfcloud.coffee.parent/
  mvn clean install

and
Rightclicking on one Maven project going to Maven> Update Project > Selecting All
removed the errors.
But when opening SuperBrewer3000.xmi in text edtior in org.eclipse.emfcloud.coffee.model I get following errors:

hi @ndoschek,

thank you for the information. To fix the issue above with WorkflowAnalyzerServer.launch it helped me to go to Run Configurations > Select WorkflowAnalyzerServer > Plug-In Tab > Select All > Run.

But I still struggle to debug for example the WorkflowAnalyzer. I played around a bit with the workflow diagram and commited a small working example. But now I always get :

root INFO Analyze file:///home/user/GIT/coffee-editor/backend/examples/SuperBrewer3000/superbrewer3000.wfconfig

    at Pipe.onStreamRead [as onread] (internal/stream_base_commons.js:94:17)

If I understand the docs correctly I have to start the workflowanalysis server (port 5083) via eclipse as well as the Browser Frontend & Backend via vscode. Or do I also have to start other services as well manually like the modelserver?

Here is my complete log:

In the logs there are also 2 nullpointerexception which I always get, but they seem like to not be severe exceptions.

root INFO ModelServerBackendContribution: 23:38:28.414 [qtp296204898-36] WARN io.javalin.Javalin - Uncaught exception in WebSocket handler
java.lang.NullPointerException: null
        at org.eclipse.emfcloud.modelserver.emf.common.DefaultModelResourceManager.isResourceLoaded(DefaultModelResourceManager.java:216)

I also noticed that AnalyzeWorkflowTest fails when I run it as a JUnit test.

On the line String analyzeResult = new AnalyzeWorkflow(model, config).generate(); the process which runs the test gets terminated.
When I debug the test I get ``Source not found`

Putting the line in a try catch which logs the error I get "org.eclipse.emf.common.util.BasicEList$BasicIndexOutOfBoundsException: index=0, size=0".

To give some context what I'm trying to do:
I want to to be able to add multiple workflows to my model (not just on the machine) and execute the analysis individually (since this seems to be easier than combining all).
Sadly I'm not on a current version, because of the issues that the current master versions have. A version I was able to get working ist on commit hash 9a488d0e63a47e59b2c2c82de64952ca331f4161.

Thank you and best regards

After some more digging I found out how to set the needed cli parameters to get the services running seperatly.
The errors I mentioned above I still get, but I can't tell what is causing them.

Hi @Deel96, about the AnalyzerWorkflowTest, I quickly debugged a little into it and the issue is that the resource cannot be loaded in the method AnalyzerWorkflow#loadWorkflowConfiguration (if you set a breakpoint here it should get hit in any case).

Unfortunately the test files SuperBrewer3000.wfconfig and SuperBrewer3000.coffee in this package are outdated (e.g. the nsUris and model elements have changed).
If you replace the contents with the updated ones from the workspace (https://github.com/eclipse-emfcloud/coffee-editor/blob/master/backend/examples/SuperBrewer3000) you should get a running test case here.
But you will have to adapt the expected results file (SuperBrewer3000.result) as well of course to get a successful test result.

HTH and BR,
Nina

PS: I will consider this in the course of the update of the coffee-editor and will fix it there.
