描述

Hi i am attempting to call the vscode.java.resolveMainClass with a single argument (the arguments param being array with one entry, the uri) being the uri to a file which is part of a project to which jdtls has been attached to with the java-debug extension enabled. If i try to do that, i get empty response, no errors seemingly. If i pass no uri, just call the command to resolve the main classes it returns fine, the issue here is that i have single jdtls instance which has multiple workspaces / projects attached to it, and so i would like to use the argument to narrow down the result to only the current workspace / context by passing the uri. According to the implementation, it is supposed to handle file uris passed as the first and only argument to this method to use it to resolve the result in ResolveMainClassHandler

研究方向

從 JDTDelegateCommandHandler.java:94 開始,沿著 vscode.java.resolveMainClass 路徑進入 ResolveMainClassHandler。使用單一檔案 URI 重現 workspace/executeCommand 請求,然後驗證引數在不發生 String-to-ArrayList cast failure 的情況下得到處理,並且主類結果已縮小到相關專案。
