Description Christian Thoens

Exporting stem.products causes the following error:
"Unable to find feature: org.eclipse.equinox.executable"
Adding the Eclipse Delta Pack for 3.6 to the target platform fixes this, but the exported STEM version is not usable. It's possible to create a STEM-project, but when clicking on a button to create a STEM-component (DiseaseModel, PopulationModel, ...) nothing happens.

Hi Chris,

Do you get a stack trace (in the Error Log) after clicking the buttons?

Error log

Here is the error log from my home computer (windows 7 64 bit).

Heh.  That's lovely.

An unresolved compilation error like this should've produced an error log when the Eclipse Product export finished.  Could you check for it and attach too?

I think this is a Java 5/6 compliance issue.  The unresolved compilation error is a @override annotation on an interface method.  I don't think this was supported in Java 5.  Forcing the compiler to use 6 compliance should fix it.

Also could you try adding the following lines to org.eclipse.stem.ui/build.properties then try re-exporting:

javacSource=1.6
javacTarget=1.6

If that doesn't work, in org.eclipse.stem.ui/META-INF/MANIFEST.MF, change the Bundle-RequiredExecutionEnvironment from "J2SE-1.5" to "JavaSE-1.6"

Built logs

Hi Matt,

Now it works. I did several things. I have set the Bundle-RequiredExecutionEnvironment to 1.6 and in the project properties I changed the JRE in the build path from 1.5 to 1.6.

I can open the wizards now, but it still says that error occured during the product export. A stack trace is not available, but I attached the build logs.

Excellent.  Thanks Chris.

Same issue in those logs.

I committed manifest changes for:

org.eclipse.stem.ui.diseasemodels.multipopulation
org.eclipse.stem.ui.foodproduction
org.eclipse.stem.ui.populationmodels
org.eclipse.stem.ui

to change min execution environment from 5 to 6 to reflect the Java 6-specific code in those plugins.

Can you update and try again?  Thanks

No errors occur anymore.

Thanks Matt
