【问题描述】：
我正在尝试创建一个 RCP 应用程序，我想在其中绑定一个 bean 中的变量以查看。 bean 的代码#
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 的代码
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);
}
}
我在 manifest.mf 中添加了以下依赖项这是我的 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
运行代码时出现错误 -
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"
但是，我在 MANIFEST 中添加了这个依赖项，我可以在项目中看到这个 jar。 有什么想法吗？
谢谢！

【问题讨论】：
-
工作空间.metadata 目录中的.log 文件中是否还有更多关于解决问题的消息？
-
是的，有.... 我正在附加日志文件。谢谢！

如果您使用的是 Eclipse RCP 版本，则有一个名为
Target Platform State的视图。提到的插件在那里列出吗？您可以过滤名称。如果是这样，请检查Run Configuation是否正在加载插件。
