This questions does not relate directly to LSP4J, but to the plugin connecting a language server with the Eclipse IDE.
I registered a run configuration with a file ending via the LSP4E plugin, and the language server starts correctly when I open a file and syncs the text files when the file gets edited.
In the LanguageServer.initialized() implementation I registered the hover capability with :
public CompletableFuture<InitializeResult> initialize(InitializeParams params) {
final InitializeResult res = new InitializeResult(new ServerCapabilities());
res.getCapabilities().setHoverProvider(Boolean.TRUE);
res.getCapabilities().setTextDocumentSync(TextDocumentSyncKind.Full);
.... (more)
return CompletableFuture.supplyAsync(() -> res);
}
The server response correctly after initialize :
{"jsonrpc":"2.0","id":"1","result":{"capabilities":{"textDocumentSync":1,"hoverProvider":true}}}
Via the the console jsonrpc message exchange is logged, when I try to rename or jump to definition the appropriate request is made. But not so with the hover request (Im putting the mouse cursor over a text token or select a word). It seems to me, the hover is not triggered by the plugin.
Any ideas would be greatly appreciated.
