Create an e4 application with Tutorial 4 [message #1807955]

Hello, I'm evaluating the e4 application with JavaFX OSGi. I follow the tutorial 4 https://wiki.eclipse.org/Efxclipse/Tutorials/Tutorial4 but I have some problem to compile. It seems to be an old tutorial (java 7, now I use java 8) and the project structure generated with the wizard (Eclipse 2019-03, efxclipse 3.5.x) isn't compilable...
It's always maintained? Someone can help me?
For example, the default manifest.mf contains default Require-Bundle, but some bundles can't be resolved, my target runtime isn't correctly configured? or it's old bundles (not needed anyway or renamed)?
org.eclipse.fx.ui.workbench.fx,
org.eclipse.fx.ui.theme,
org.eclipse.fx.ui.di,
org.eclipse.fx.ui.databinding,
org.eclipse.fx.ui.services

I followed the presentation in Zurich of Tom Schindl last November in the JavaFX Days and I was very interested in this product but the documentation gives the impression of draft. In case of problems, we do not know if it's due to a bug, an old documentation, a library not up to date (nightly!). Learning becomes difficult.

Let's take a look at the problems/questions one by one:
* First off all everything in the tutorial still is correct (although it was created back in the days of Java-7 :-)
* If you get resolve errors this means you have not setup the target-platform correctly all bundles you mention are in the target-platform and should resolve
* On the out-dated remark - you are right but we simply don't have the cycles to work on all that - we/I fully understand that this gives a wrong impression but I'm unable to change that in the short/mid-term
* Is the project production ready - absolutely there are many large scale applications built (> 10 millions budget) and as you see on github we are actively maintaining and extending the framework

I'm not sure from what background you are. If you have experience with e4 on SWT all knowledge should be directly transferable to "e4 on JavaFX".

Hello Thomas, thanks for answer.
I'm a newbie in OSGi and e4. I will use equinox for modularizing our server applications and use e4 on JavaFX for the same things for the desktop. As I use Java 8 (and in the future Java 11), the documentation for Java 7 don't really help me.
I agree with you, I think my problem is that the target-platform isn't correctly configured. I have added nightly repo (https://download.eclipse.org/efxclipse/runtime-nightly/site/) in my eclipse (2019-03 with e(fx)clipse 3.5.0.20190220800) and I have installed Target Platform features like the tutorial. See my installation details here https://send.firefox.com/download/7315ff046938e189/#t0zRhtKgWFYVIO__mLRjGQ. Could you help me? or explain/redirect to a documentation for basic target-platform configuration?

So you did NOT setup a target platform because you point still to the your ide one!

Yes, you are right. Another question, what is the advantage of using "JavaFX e4 Application" instead of "JavaFX OSGi Application"? I'm newbie with e4, and I will only a modular JavaFX application.

Well it depends a "JavaFX OSGi Application" does not have all the features you get from e4 (like the Application-Model, Command-Handler-Framework, ...) so it is more bare bone
