Backport to 4.0.x - [Eclipse Integration] GPE's "GWT Compile" doesn't create the errai classes

XMLWordPrintable

    • Release Notes
    • Hide
      GWT web projects must be compiled using GWT Compile before being deployed on the server. However, GWT Compile did not create the required Errai classes when compiling GWT web projects and, as a result, errors occurred during application deployment. To solve this issue, the Maven Configurator Plug-in for GWT was modified. Now GWT Compile creates the required Errai classes and applications deploy without errors.

    • Documented as Resolved Issue

      We're trying to achieve the following workflow for the user inside Eclipse/ GPE / JBoss Tools:

      • create project
      • execute Google > GWT Compile
      • Run As > Run On Server
      • browse the application

      When a gwt maven project is detected, GPE sets the GWT compilation output directory to target/<artifactId>-<version>/. So ultimately we could automatically mark that folder as deployable for WTP and pretty much achieve that ideal workflow.
      Until this is done automatically, we can do it manually. Here's a slightly more complex workflow :

      • Create a new GWT Project from JBoss Central
      • Right-click on project > Google > GWT compile
      • Add the Kitchensink module
      • Click on Compile. Upon completion, a target/<artifactId>-<version> folder is created
      • Right-click on project > Properties > Deployment Assembly
      • Click Add > folder > select target/<artifactId>-<version> click ok to complete
      • Right-click on project > Run As > Run on server
      • select JBoss AS7 / EAP, OK
      • Project deploys without errors
      • KitchenSink.html is displayed in browser, with the full form.

      Problem is, when the page is displayed, the following exceptions appear in the AS console :
