java - javaCompletionProposalComputer for Eclipse JSDT 的内容协助没有给出建议

Question

针对 Eclipse JSDT 的 org.eclipse.wst.jsdt.ui.javaCompletionProposalComputer 的内容协助未提供建议。

在首选项 -> JavaScript -> 编辑器 -> 内容辅助 -> 高级“Nodeclipse Proposals”可见并已选中。

根据 Bananaweizen 的建议 Content assist for Eclipse JSDT based Editor

在plugin.xml中

<extension point="org.eclipse.wst.jsdt.ui.javaCompletionProposalComputer"
   id="nodeclispe_textual_proposals"
   name="Nodeclipse Text Proposals">
   <proposalCategory icon="icons/npm/npm.gif"/>
 </extension>
 <extension point="org.eclipse.wst.jsdt.ui.javaCompletionProposalComputer"
   id="NodeclipseProposals"
   name="Nodeclipse Proposals">
   <javaCompletionProposalComputer
      class="org.nodeclipse.ui.contentassist.JSDTProposalComputer"
      categoryId="org.eclipse.ui.texteditor.textual_proposals">
      <partition type="__java_javadoc"/>
   </javaCompletionProposalComputer>
 </extension>

JSDTProposalComputer 只是 NodeContentAssistant
的包装(实现 IContentAssistProcessor)，非常适合基于 TextEditor 的编辑器。

public class JSDTProposalComputer implements IJavaCompletionProposalComputer {

    IContentAssistProcessor assistant = new NodeContentAssistant();

    @Override
    public List<ICompletionProposal> computeCompletionProposals(ContentAssistInvocationContext context, IProgressMonitor monitor) {
        return Arrays.asList(assistant.computeCompletionProposals(context.getViewer(), context.getInvocationOffset()));
    }

    @Override
    public List<IContextInformation> computeContextInformation(ContentAssistInvocationContext context, IProgressMonitor monitor) {
        return Arrays.asList(assistant.computeContextInformation(context.getViewer(), context.getInvocationOffset()));
    }

所有代码都在 GitHUb contentassist 包 https://github.com/Enide/nodeclipse-1/tree/master/org.nodeclipse.ui/src/org/nodeclipse/ui/contentassist 上

正如@zulus所说:

try to add activate="true" in javaCompletionProposalComputer and remove

有效的是:

<extension point="org.eclipse.wst.jsdt.ui.javaCompletionProposalComputer"
   id="nodeclispe_textual_proposals"
   name="Nodeclipse Text Proposals">
   <proposalCategory icon="icons/npm/npm.gif"/>
 </extension>
 <extension point="org.eclipse.wst.jsdt.ui.javaCompletionProposalComputer"
   id="NodeclipseProposals"
   name="Nodeclipse Proposals">
   <javaCompletionProposalComputer
      class="org.nodeclipse.ui.contentassist.JSDTProposalComputer"
      categoryId="org.eclipse.ui.texteditor.textual_proposals"
      activate="true">
   </javaCompletionProposalComputer>
 </extension>
