Setting up Eclipse RCP Oxygen+ E(fx)clipse and running Tutorial2 [message #1772928]

So, I am having trouble setting up Eclipse RCP IDE with E(fx)clipse and then running a ViewPart with JavaFX code embedded in it. Here are the step I followed based on the online resources I was able to find:

1. Downloaded and unpack `eclipse-rcp-oxygen`
2. Added JDK 1.8 (v102) as default JRE in Eclipse
3. Installed `e(fx)clipse - IDE` v3.0.0.201705220750 via Oxygen update site
4. Restarted Eclipse RCP IDE
5. Edited the active Target Platform to include the `FX Target` features from:

http://download.eclipse.org/efxclipse/runtime-released/3.0.0/site/

Most features had version 3.0.0.201706050601.
Also unchecked `Include required software` as instructed by installation steps

6. Created new `Plug-in Project` using `JavaFX Eclipse 3.0 Project` template

And this is where things break.

MANIFEST.MF shows errors for all `javafx.*` dependencies in `Import-Package:` section.

The official tutorial has no additional instructions.

I tried removing those imports as instructed at some of the forums. That gets rid of the errors. However, once I try to create and start an `Eclipse Application` launcher, I get a bunch of problems upon launch:

- "Missing constraint" error for:

org.apache.xmlrpc
- Missing Constraint: Import-Package: javax.xml.bind; version="0.0.0"

- Multiple "2 version of singleton" errors of the kind:

org.eclipse.core.runtime
- 2 version of singleton `org.ecilpse.core.runtime` exist

Any ideas?

a) you should NOT add the "Target Platform Feature" feature if you want to write an Eclipse Plugin if you want a 3.x plugin then "RCP 3.x Target Platform Feature"
b) the import statements are bogus and if they are still there this is a bug in the tooling, just remove them

Thank you Thomas,

When launching the Eclipse Application launcher I get a missing constraint validation for javax.xml.bind version 0.0.0. Despite that, I am now actually able to run the the tutorial's `ViewPart` inside the `Eclipse Oxygen` + `RCP 3.x Target Platform Feature` target platform.

The target platform I need to integrate JavaFX code into is unfortunately rather old, it targets Eclipse Helios 3.6.

I am able to install the e(fx)clipse target feature after unchecking "Include required software". However, when attempting to launch the tutorial app I get a bunch of missing constraint violations requiring Eclipse 3.7.0 core.runtime/swt/jface/ui.workbench plugins and 3.10.0 for org.eclipse.osgi, and no ViewPart is displayed or available in the launched instance.

Is there prior version of e(fx)clipse runtime/target feature that supports 3.6? Or any other workaround I might be able to take?
