Eclipse 插件：TextSelection 无法解决
我正在尝试开发我的第一个插件。
插件应操作活动文本编辑器中所选文本的内容。
我从“备忘单”中的“hello world”示例开始，效果非常好。
当尝试修改时，我发现该项目无法识别许多类型。
我将以下 jar 添加到项目构建路径库中：
- org.eclipse.jface.text_3.5.1.r351_v20090708-0800.jar
- org.eclipse.text_3.5.0.v20090513-2000.jar
- org.eclipse.ui.editors_3.5.0.v20090527-2000.jar
现在代码编译完美。
ISelection iSelection = null;IEditorSite iEditorSite = window.getActivePage().getActiveEditor().getEditorSite();if (iEditorSite != null) {- <代码> ISelectionProvider iSelectionProvider = iEditorSite.getSelectionProvider(); <代码>
- if (iSelectionProvider != null) <代码>
- {
iSelection = iSelectionProvider.getSelection();selectedText = ((ITextSelection)iSelection).getText();}}
问题在第 08 行。虽然 Eclipse 识别 ITextSelection 接口，但在运行时我得到无法解析类型异常。
尝试部署代码时，我在部署日志中收到以下行：
无法解析导入 org.eclipse.jface.text
I am trying to develop my first plug-in.
The plug-in should manipulate the content of the selected text in the active text editor.
I started with the “hello world” example from the “Cheat sheet” which worked perfect.
When tried to modify I found that project not recognizing many types.
I added the following jars to the project build path libraries:
- org.eclipse.jface.text_3.5.1.r351_v20090708-0800.jar
- org.eclipse.text_3.5.0.v20090513-2000.jar
- org.eclipse.ui.editors_3.5.0.v20090527-2000.jar
Now code compiles perfect.
ISelection iSelection = null;IEditorSite iEditorSite = window.getActivePage().getActiveEditor().getEditorSite();if (iEditorSite != null) {ISelectionProvider iSelectionProvider = iEditorSite.getSelectionProvider();if (iSelectionProvider != null){iSelection = iSelectionProvider.getSelection();selectedText = ((ITextSelection)iSelection).getText();}}
The problem is in line 08. although eclipse recognize the ITextSelection interface, at runtime I get cannot resolve type exception.
When trying to deploy the code I get the following line in the deploy log:
The import org.eclipse.jface.text cannot be resolved

您是否尝试在“运行配置”对话框中打开“插件”选项卡并单击“添加所需插件”按钮？
它可能会为您添加正确的运行时依赖项。
另请参阅插件的依赖项选项卡中的相同按钮项目：

Did you try, in the Run configuration dialog, to open the "Plugins" tab and click the button "add required plug-ins" ?
It might add the right runtime dependencies for you.
See also that same button in the dependencies tab of your plugin project:
