eFX Tutorial 2 gives error results [message #1271993]

Sun, 16 March 2014 16:46

Eclipse User

When running the eFX Tutorial 1 with Kepler SR2, I encountered no difficulties. All worked as expected.

When trying Tutorial 2, I noticed in the screenshot for step 4 that the image displayed a drop down list for Target Eclipse Version that reads "3.7". When I executed this step, the choice is "3.5 or Greater".

In the screenshot for step 5, my default Execution Environment was JavaSE-1.7 instead of the image's JavaSE1.6. I ran the tutorial steps with both environment settings - identical erroneous results in each case.

In the screenshot for step 7, the sample screenshot includes a selected checkbox labelled "With repackaged JavaFX". The checkbox and label were not visible when I ran the tutorial. My suspicion is that this may have caused the resulting generated project to contain errors.

At step 8, I stopped because the resulting artifacts were all in error:
in Activator.java, unresolved import statements such as:
import org.eclipse.jface.resource.ImageDescriptor;
import org.eclipse.ui.plugin.AbstractUIPlugin;

in MyViewPart.java, unresolved import:
import org.eclipse.fx.ui.workbench3.FXViewPart;

I noted that step 8 indicates that a new OSGI bundle should be the result of steps 1-7. In step 4, should the Target Platform be set to an OSGI Framework ?

By manually adding the JavaFX Container to the project classpath I eliminated the errors in Activator.java but the import statements in MyViewPart still throw an error.

I downloaded the latest nightly build of the preconfigured bundle of eclipse(Luna) plus eFX and tried the tutorial with that. After step 7, the new project is in the same state - Activator.java is error free but MyViewPart.java still has error "import org.eclipse.fx.ui" cannot be resolved.

I also noted that MANIFEST.MF also gives error "Bundle 'org.eclipse.fx.ui.workbench3' cannot be resolved"

In case it is relevant, I am using java 7 build 1.7.0_51-b13

Ok - I think the tutorial is wrong and needs to be fixed! I'll do that
later on and come back once it is done.

Thanks Tom.
In case it matters, I followed the instructions at http://www.eclipse.org/efxclipse/install.html#for-the-ambitious

to install eFX version 0.9.0

Hi Tom,
Any update on this? I am using Kepler + e(fx)clipse 0.9
There seems not such bundle named org.eclipse.fx.ui.workbench3
in the installation and the update site:
http://download.eclipse.org/efxclipse/updates-released/0.9.0/site_assembly.zip

(I did see the plugin in 1.0 update site. So is the tutorial for 1.0 only?)

Hi,

I've fixed the tutorial. If you are on Kepler you need to use the 0.9.0
release it won't work with the nightly site because there've been
changes to the equinox framework.

Hi Tom.
I tested the revised tutorial 2. I've now used the release 0.9 update site when defining the target environment in step 1.8

The screen image I see in step 6 says "JavaFX Eclipse 3.x Project" instead of "JavaFX Eclipse 3.x ViewPart".

At step 8, I again see lots of errors. I will attach a screen image (efx-tutorial2-errorsAtEnd.png) and the generated project artifacts (MyFXViewPart.zip) at the start of step 8

At the end of step 7 I saw an unexpected popup window asking if I wanted to open the Associated Perspective. I chose to not open it.

I captured screen images as I went along. Those are also attached as zip file $screen.zip

Let me know if I can assist in any way with resolving this problem.

If anyone else using Kepler SR2 was able to successfully arrive at step 8 without any errors, please let us know. That would indicate there is something unusual about my environment....

Hi,

Can you show me your target platform settings.

Please note that Step 5 has changed to "Select "Default: Default target
for the running platform". Click the "Next" button.".

Were you referring to step 1.5 when you mentioned "select default target" ?
Attached are my target platform settings using the new target platform as was previously specified in step 1.

I tried (see target-07.png) to instead add the target to the default target platform and saw the attached errors in target-08.png.

Right your screenshot looks like you used "Nothing: Start with empty
target" which wrong.

You need to use "Default: Default target for the running platform" which
will give you as the initial entry "${eclipse_home}" and then you add
the p2 site.

I'm sure I used "Default: Default target for the running platform"

When I finished, I was left with two target platforms named "Running Platform". Is that correct ? I now wonder which one I actually activated.

Did you intend that I should be instead editing my default running platform ?

If I do that, the generated project has no errors.

Attached is the html to describe the changes to step1 of the tutorial if you intended to edit the default target platform.

Hi,

No i don't not really meant that you modify the current one but add a
new one. You could haven given it a different name.

Yes and the you should enable the newly added one.

No but the result is the same, it now harder for you to get back into
the default state but probably that's ok.

I reworded the wiki to make my intend clearer.

Thanks Tom.
I was able to complete the tutorial2 using a fresh eclipse and exactly following your revised instructions.

Is there a way to run the generated project outside of eclipse ?
(I realise this question is a new topic - however I was unable to discerne the use case for the tutorial)

Also, do you need to implement the same changes for step1 in the next two tutorials ?
Or create a link to a different page for setting up the target platform .....

No - the descriptions there are for pure e4 applications and there you
use the complete target platform provided by us. So the description
there is fine.

I can't follow you? All other tutorials use the target platform provided
in this one repo so the description is perfectly ok.

What do you mean with "run outside Eclipse"? You've developed an
Eclipse-RCP-Plugin which can only run inside a full blown Eclipse RCP/IDE.

What do you want to develop? A plugin which integrates itself into an
Eclipse-SWT-RCP/IDE-Application or a pure e4+JavaFX application. If it
is the latter then Tutorial 3 & 4 are what you are looking for.
