Hi Svetlozar Iliev (@asmodeus812), I'm an AI Support assistant here to help with your issue. While the team reviews your request, I wanted to provide some possible tips and documentation that might help you in the meantime.
Solution
- The JDTLS handler expects the first entry in
argumentsto be a list, not a string. Wrap your URI in an extra array. For example:This way,{ "command": "vscode.java.resolveMainClass", "arguments": [ [ "file:///home/asmodeus/.projects/javahehe/src/main/java/com/mycompany/app/App17.java" ] ] }arguments.get(0)will be a list (ArrayList) rather than a raw string.

- The JDTLS handler expects the first entry in
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
