Hello All,

Last time, I've been strugling with running any plug-in project which is using JavaFX and I stucked... I'm getting below exceptions:

I've tried Eclipse, Eclipse EE, Eclipse RCP (all Luna version) and behaviour was exactly the same.

Simple applications with JavaFX are working without any problem, plugin projects are also working well, but mixing this two things is causing above exception .

Any idea why it is happening ? I will be really grateful for any help.

Thank You.

Do you have the necessary Import-Package directives in your MANIFEST.MF?
It should hold something like

> Import-Package: javafx.animation;version="2.2.0",
> javafx.application;version="2.2.0",
> javafx.beans;version="2.2.0",
> javafx.beans.binding;version="2.2.0",

> javafx.collections;version="2.2.0",
> javafx.collections.transformation;version="8.0.0",
> javafx.concurrent;version="2.2.0",
> javafx.css;version="8.0.0",

Not sure, but doesn't the error message report an issue regarding the Java version? Do you run your application using Java 8?

No this resolve does tell exactly the opposite - he runs java8! This bundle activates if your version is lower than java8 showing a warning that efxclipse is disabled because it requires java8. I know this is strange nur in the early days of java8 we had many people wondering why efxclipse did not work in their env. I think we should remove this bundle in 2.0.

Solved ! (almost Smile)
Yes, I'm using Java 8. As Thomas wrote, problem was in Manifest.mf (lacking dependencies for JavaFX).

After changes in Manifest.mf all exceptions disapeared apart from the first one about Java version ("org.osgi.framework.BundleException: Could not resolve module: org.eclipse.fx.ide.java6 [219]"). I've made few tests and it turned out that this exception appeares after installing JavaFX plugin in Eclipse and it is thrown every time when I'm running Eclipse Plugin project (even if the project does NOT use JavaFX. So it seems that there are some problems with compability between JavaFX plugin and Eclipse).

Thanks for help !

Hi,

No this plugin is NOT wrong nor BUGGY but works as designed! It is there
when you installed e(fx)clipse because all TOOLING bundles require Java8.

So when Java8 was not default for most people to run their IDE people
have been wondering why they did not see all the e(fx)clipse tooling
stuff (including very seasoned devs at EclipseCon Tutorials) although
the bundles where installed appropriately through p2.

The bundle refusing the start under Java8 is a bundle who would bring up
a dialog telling you that you are running e.g. on Java 5 / 6 / 7 and the
tooling will not be functional (including to disable the warning for the
future!).

It's unfortunate that Equinox croaks with such a big error message since
Luna and as I already replied to Dirk we might now safely remove this
helper bundle and assume that people are smart enough to run their IDE
with Java8 if they are doing JavaFX dev.

Tom
