Is there any way to achieve 'jump from method implementation to interface method definition'?

[JohnWickzzz]

For now, I use lspsaga & glance plugins. I found that they offer the function 'Lspsaga goto_definition' and 'Glance implementations' can use for jump from definition to implementation.
I read the plugin doc and search from the network, but don't find a convenient way jump from method implementation to interface method definition. Is there something I'm missing about the use of plugins? Or is there any other way to do it?

I dont really get your point. What lang and lsp do u use?

Can u give us some screenshots or examples of what u want to achieve? After all, they're commands from different plugins, i'm not sure why u want do combine them.

Sorry, forgot to say, I use java and jdtls.

Like this, a service method in java project controller or service class.

I use 'Lspsaga goto_definition' can jump to interface file.

Use 'Glance implementations' jump to implementation file.

If I'm in the impl class method, how can I jump to the interface method.
（其实就是Java中的接口和实现，现在通过glance插件可以从方法调用处或者接口函数那里跳转到具体实现类，但是现在不知道如何在实现类跳转到接口函数）

hmmm, this seems like a tricky one. Personally i had never wrote one line of java before.
I think the closest shot is to use Lspsaga finder, but i'm not sure if it meets your needs.

Thanks for you help. I tried the Lspsaga finder, but it not show the interface method.

TBH, neovim native lsp doesn't support such feature (jump from implementations to interfaces) and I think it's a fake demand. It can be easily achieved by Lspsaga goto_definition actually. Just move cursor to FeedbackService and gD.

I think this really depends on the language server u're using, bc the formal specification doesn't mandate that servers must implement a textDocument/switchSourceHeader method. I know clangd supports this (extra) feature and we have a mapping for it, but for Java, IMO u should contact ur LSP vendor or check their documentation to see if there's a similar feature available.

😁 In jdtls latest version 1.31.0, this issue Implement go to declaration has been fixed. Just use :lua vim.lsp.buf.declaration() or create a shortkey.
