未解決の要件：Require-Bundle：org.Eclipse.core.databinding.beans; bundle-version = "1.2.200"

Beanからビューに変数をバインドしたいRCPアプリケーションを作成しようとしています。 Beanのコード＃

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;
}

}

VIewのコード

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);
}
}

次の依存関係をmanifest.mfに追加しました。これが私のMANIFEST.MFです。

Manifest-Version: 1.0
Bundle-ManifestVersion: 2
Bundle-Name: Editor
Bundle-SymbolicName: com.app.Editor;singleton:=true
Bundle-Version: 1.0.0.qualifier

      com.app.editor.commands,
       com.app.editor.functionalities,
       com.app.editor.perspectives,
        com.app.editor.views

コードの実行中にエラーが発生します-

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"

しかし、私はこの依存関係をMANIFESTに追加し、プロジェクトでこのjarを確認できます。何か案が？

ありがとう！

私はこの問題を解決しました。なぜこれが起こったのかはわかりませんが。

実行->構成の実行...->プラグインタブ->必要なプラグインの追加->プラグインの検証->実行

これで私の問題は解決しました！

私にとって、プラグインを削除して再度追加することはうまくいきました... Preferences > Plug-in Development > Target Platform、実行中のプラットフォームのターゲット定義を削除してみてください-> Click Apply、次にデフォルトに戻すか、追加したい必要なプラグインを追加します。
