Adding custom code to "Build & Deploy" button in KIE workbench

[afs...@yahoo.com]

Hello

I would like to add custom code to the "Build & Deploy" button in KIE Workbench under Project Authoring -> Tools -> Project Editor.

I need to run my own maven commands when the button is clicked instead of what it regularly does. Is this possible if I modify the source?

Also I need to add a radio button in that tool bar.

Can anyone provide insight on which project I would need to modify for this and which HTML page?

Thank you,

Afshad

KIE Workbench is written with GWT; so you're not going to find an HTML page for the Project Editor nor a JS fragment for it..

The Project Editor source code is however here. Search for "buildOptions" and you'll see how the "Build & Deploy" button is created and configured etc. 

You'll be able to use MenuFactory.newTopLevelCustomMenu() to add a RadioButton to the menu bar. See here for an example.

You'll need to recompile kie-wb-common and kie-wb-distributions for any changes you make to be included in the WAR (as a GWT re-compilation is required).

The workbench makes extensive use of the Uberfire framework. Have a read to help better understand the code.

Uberfire is written and maintained by the same developers as KIE Workbench.

With kind regards,

Mike

Thanks for the response Michael

In my WAR there was no kie-wb-common-project-editor-client-6.1.0.Final.jar so I downloaded the war made my changes (simple change of changing menu text to "Test" instead of "Build & Deploy") built it and added it to the war but it did not seem to take any effect. My original war did not even contain this jar so I dont know how its working without it.

Also what is the kie-wb-distributions you are talking about? My existing war does not have any such jar. Why would it need to be recompiled as well if no changes are being made to it?

Thank you. Appreciate your help.

[Michael Anstis]

GWT applications require a recompilation of the "client side" source code to regenerate the JavaScript.

All Workbench related JARs named *-client*.jar are only used during the GWT compilation phase and not included in the WAR (as it is not needed one the Java Script has been generated).

Unless you compile your modified kie-wb-common JAR **AND** kie-wb-distributions any changes you make elsewhere will not be not be evident in the webapp.

kie-wb-distributions is the modules that produce the WARs.

Thank you Michael. I was able to build kie-wb-common. However while building kie-wb-distributions from either eclipse/command line/IDEA i get the classpath too long error. I googled about this but everyone has run into the same issue and no solution. I only have windows. With IDEA i tried starting with idea.dynamic.classpath=false

but that didnt work either i get the error below. Is there any other property i should be setting in idea.properties?

Yes, sadly it is a well known limitation of Windows :(

There are various work arounds; see http://stackoverflow.com/questions/10519558/createprocess-error-206-the-filename-or-extension-is-too-long-when-running-main

InteliJ uses the "Use a special class loader which reads the classpath from a config file" approach when - as far as I know - the "idea.dynamic.classpath" flag is true.

Hello Michael

So we are building on linux however  it does not seem to be generating anything but a test jar in each of the folders and subfolders. Is this normal or should it be generating something else? I am using the command "mvn clean install" in the room of kie-wb-common. 

For example this is what is see in each of the target directories: kie-wb-common-6.1.0.Final-tests.jar

Also after building kie-wb-common, we have to build kie-wb-distribution and that will generate a war file?

Thanks for your help.

[Michael Anstis]

If you do this you should build the necessary WARs:

1. cd ./kie-wb-common
   
2. mvn clean install
   
3. cd ../kie-wb-distributions
   
4. mvn clean install
   

The WARs will be in the following:

• ./kie-wb-distributions/kie-drools-wb/kie-drools-wb-distribution-wars/target
  
• ./kie-wb-distributions/kie-wb/kie-wb-distribution-wars/target
  

We follow this exact procedure whenever we build the application.

With kind regards,

Mike

Hi Eddy,

were you able to add additional maven commands to execute. I have a similar requirement. Could you please share what you did?

Thanks,

Tarun

[Toni Rikkola]

If you end up making something reusable the Guvnor project is happy to take pull requests :)

Something that possibly digs the command out of the pom.xml and let's the user select what he does. This doesn't necessary make it into the KIE workbench, but Guvnor is used by much more than KIE/Drools/JBPM.

[ravi pillala]

Hi Afshad,

I have the same requirements as what you described. Can you share what you have done or provide the git links if you commit your changes.

Thanks
Ravi

[Afshad Dinshaw]

It was a very long and I don't remember we did not do anything about it.
