Creating a JavaFX plugin and "Require-bundle" problem

[Adam W]

Hi,

I am trying to add a plugin for JavaFX based on efxclipse plugin for Eclipse.

I wanted to add a command for validating FXML and I run into a problem.

When I try to use FXMLValidator from org.eclipse.fx.ide.fxml bundle I keep

getting ClassNotFoundException even though I have Require-bundle: org.eclipse.fx.ide.fxml

in the manifest file.

I am able to import and use some other classes from some other bundles of the efxclipse plugin.

Can this be because the MANIFEST.MF of the org.eclipse.fx.ide.fxml bundle is missing Export-Package?

I looks like this:

Manifest-Version: 1.0

Bundle-ManifestVersion: 2

Bundle-Name: Fxml

Bundle-SymbolicName: org.eclipse.fx.ide.fxml;singleton:=true

Bundle-Version: 3.0.0.qualifier

Bundle-Activator: org.eclipse.fx.ide.fxml.Activator

Require-Bundle: org.eclipse.ui,

 org.eclipse.core.runtime,

 org.eclipse.jface.text,

 org.eclipse.ui.editors,

 org.eclipse.wst.sse.core;bundle-version="1.1.600",

 org.eclipse.wst.xml.core;bundle-version="1.1.600",

 org.eclipse.wst.xml.ui;bundle-version="1.1.200",

 org.eclipse.wst.sse.ui;bundle-version="1.3.0",

 org.eclipse.xtext.ui;bundle-version="2.3.0",

 org.eclipse.jdt.core;bundle-version="3.7.0",

 org.eclipse.fx.ide.model;bundle-version="2.3.0",

 org.eclipse.jdt.ui;bundle-version="3.7.0",

 org.eclipse.fx.ide.ui;bundle-version="2.3.0",

 org.eclipse.ui.ide;bundle-version="3.7.0",

 org.eclipse.xtext.common.types.ui;bundle-version="2.3.0",

 org.eclipse.xtext.xbase.lib;bundle-version="2.3.0",

 org.eclipse.core.databinding;bundle-version="1.4.0",

 org.eclipse.core.databinding.beans;bundle-version="1.2.100",

 org.eclipse.jface.databinding;bundle-version="1.5.0",

 org.eclipse.core.databinding.property;bundle-version="1.4.0",

 org.eclipse.wst.validation,

 org.eclipse.ui.workbench.texteditor;bundle-version="3.7.0",

 org.eclipse.search;bundle-version="3.7.0"

Bundle-ActivationPolicy: lazy

Bundle-RequiredExecutionEnvironment: JavaSE-1.8

Bundle-Vendor: Eclipse.org

Most likely, yes. If that class is only found in that bundle and that
bundle is not exporting the package that class belongs to, then your
bundle won't have access to it. You can try emailing the developers of
that plugin to see if there is another way to validate fxml files
using exported code, or see if they are willing to export the
package(s) you need in a future release (I had to do that in the past
with the scalaide devs).

Thank you, I will try writing them.

In the meantime I just copied the classes I need from the bundle to my eclim plugin but that is not a very elegant solution that would be accepted in a pull request I guess.
