Unresolved requirement: Require-Bundle: org.eclipse.core.databinding.beans; bundle-version="1.2.200"
Solution 1
I have solved this problem. Though I am not sure why this was happening.
Run As -> Run Configurations... -> Plugin-ins tab -> Add Required Plug-ins -> Validate plugin -> Run
This solved my problem!
Solution 2
For me, removing the plugins and adding them again worked...
Preferences > Plug-in Development > Target Platform
, try remove the Running Platform target definition -> Click Apply
, and then Restore defaults or add the required plugins which you want to add.

I am trying to create a RCP application in which, I want to bind a variable from a bean to view. Code for bean #
public class SaveFileBean implements PropertyChangeListener { private String text; private PropertyChangeSupport propertyChangeSupport = new PropertyChangeSupport( this); @Override public void propertyChange(PropertyChangeEvent arg0) { propertyChangeSupport.firePropertyChange("text", null, text); } public void addPropertyChangeListener(String propertyName, PropertyChangeListener listener) { propertyChangeSupport.addPropertyChangeListener(propertyName, listener); } public void removePropertyChangeListener(PropertyChangeListener listener) { propertyChangeSupport.removePropertyChangeListener(listener); } public String getText() { return text; } }
The code for VIew
public class NewView extends ViewPart { private DataBindingContext m_bindingContext; public static final String ID = "com.app.Editor.newView"; SaveFileBean bean = new SaveFileBean(); private StyledText text; public NewView() { } @Override public void createPartControl(Composite parent) { text = new StyledText(parent, SWT.BORDER); bindValues(); } private void bindValues() { } @Override public void setFocus() { // create new Context DataBindingContext ctx = new DataBindingContext(); // define the IObservables IObservableValue target = WidgetProperties.text(SWT.Modify). observe(text); IObservableValue model= BeanProperties. value(SaveFileBean.class,"text").observe(text); // connect them ctx.bindValue(target, model); } }
I added the following dependencies in manifest.mf Here is my MANIFEST.MF
Manifest-Version: 1.0 Bundle-ManifestVersion: 2 Bundle-Name: Editor Bundle-SymbolicName: com.app.Editor;singleton:=true Bundle-Version: 1.0.0.qualifier Bundle-Activator: com.app.editor.Activator Bundle-Vendor: APP Require-Bundle: org.eclipse.ui, com.ibm.icu, org.eclipse.core.runtime, org.eclipse.core.databinding;bundle-version="1.4.2", org.eclipse.jface.databinding;bundle-version="1.6.200", org.eclipse.core.databinding.property, org.eclipse.core.databinding.beans;bundle-version="1.2.200" Bundle-RequiredExecutionEnvironment: JavaSE-1.8 Bundle-ActivationPolicy: lazy. Here is Export-Package: com.app.editor, com.app.editor.actions, com.app.editor.beans, com.app.editor.commands, com.app.editor.functionalities, com.app.editor.perspectives, com.app.editor.views
While running the code, I am getting error -
org.osgi.framework.BundleException: Could not resolve module: com.app.Editor [81] Unresolved requirement: Require-Bundle: org.eclipse.core.databinding.beans; bundle-version="1.2.200"
But, I have added this dependency in MANIFEST and I can see this jar in the project. Any idea?
Thanks!

Amos M. Carpenter about 8 yearsHad a similar issue with an unresolved requirement for junit after adding some tests, so +1 - and I think you mean
Run Configurations...

tab >Add Required Plug-ins
button (at least in Mars). -
Campa over 4 yearsThis will not solve your problem when deploying your product however. Still you'll have to find the missing dependencies and manually add them to your manifest.
