定義ジャンプ出来ない時は何が起きているのか

[xpgcrx]

定義ジャンプ出来ないときが一番困る。
何が起きているのか理解したい

[xpgcrx]

ジャンプ出来ないバッファではlsp clientがアタッチ出来ていなさそう。

ジャンプできるバッファではgを押すとlspのキーマップが出る。

ジャンプできないバッファでは出ない。

[xpgcrx]

nvim-jdtls.luaですが、設定の問題なのかわからないですが、定義ジャンプ出来たり出来なかったりします
。同じファイル上のシンボルでも、ジャンプできたり出来なかったりします。出来ないときは
E433: No tags file
E426: Tag not found:
のようなエラーメッセージが出ます。IntelliJ
IDEAではジャンプ出来るため、何かがおかしかったりするのかもしれないです

全く別の設定を試すか

同じMavenモジュール内ならちゃんとジャンプ出来るようになった気がする。
ただ複数jdtlsクライアントが立ち上がっているのがやっぱりおかしそう。
複数立ち上がっているうち一部のクライアントではプロジェクトルートが大元ではなくモジュールのルートになっており、これがアタッチされているせいな気がする。

project rootの計算関数を見直した方が良い？
それともそういう問題ではない可能性？（そもそもnvim-jdtls管轄外でjdtlsが立ち上がってたりとかしないか）
