[e4-dev] Problems with product expor

[Davy Meers <davymeers@xxxxxxxxxxx>]

Hello,

I am giving e4 a testdrive and am having problems exporting a product. To provide the context i will describe the steps i've taken:

1. Download the 4.1 release from http://download.eclipse.org/e4/sdk/
2. Install the following plug-ins:
   • Eclipse e4 Modeled Workbench
   • Eclipse e4 Modeled Workbench Source
   • Eclipse e4 Tools
   • Eclipse e4 Tools Source
3. Create e4 application using e4 Application project wizard (all the defaults are preserved)

The resulting project contains a product file. When i test the application using the command "Launch an eclipse application" the application starts without problems.

When exporting the product using the "Eclipse Product export wizard" i am unable to start the exported application.The log (attached as annex) contains the following errors :

• Product testProject.product could not be found
• NullPointerException at org.eclipse.e4.ui.internal.workbench.swt.E4Application.start(E4Application.java:126)

Can someone explain the reason why i get these errors? (Is there a known bug, what has to be done to solve these errors, ...)

I have also a question about the dependencies of the generated bundle:

When i look at the dependencies in the manifest i see that mostly Require-Bundle is used (also for e4 bundles). Is there a particular reason why Import-Package isn't used?

Kind regards,

Davy Meers
