Thats fixed by supplying: "mainClass": "${file}",
"modulePaths": ["${folder}"]Now the Debugger fails with: Debugger does not reply to runInTerminal. Is this a known issue? |

Okey, I found the comment in |

@daveleroy I'm fairly certain this isn't allowed, unfortunately...
Offerings are intended for use only with Visual Studio Products and Services and you may only install and use Marketplace Offerings with Visual Studio Products and Services.

In this case its actually possible to compile the jar and ship it with Debugger (or download it elsewhere.) The plugin itself is under Eclipse Public License - v 1.0. See https://github.com/microsoft/java-debug/blob/master/LICENSE.txt

You cannot download or in any way install software provided through the “marketplace” if it’s not a “visual studio product”. The license you link to does allow one to compile/use the software. But obtaining that software cannot be done through the marketplace (or, risk a cease and desist I guess).

If that debugger jar is somewhere else on the internet available for download and the terms and conditions of that source allow it, then we can use that.

Why do you think VSCodium has its own marketplace?

We would want the full extension https://github.com/Microsoft/vscode-java-debug which includes all the snippets and a schema for the configurations.

Incidentally, open-vsx.org is hosted by the eclipse foundation https://www.eclipse.org/community/eclipse_newsletter/2020/march/1.php

Right, I think you can also just fetch the .vsix file from https://github.com/microsoft/vscode-java-debug/releases/ and extract it as a zip.

Looks like you can in this case. Other adapters do not add the vscode package to their releases so those will probably need to be changed.

Yes. What a coincidence that the assets are not in a GitHub release... ;)
It relies on winpty and dependencies don't work on the 3.8 environment |
@LDAP for now you can probably change your configuration to not use the integrated terminal.
|
In this case the Server errors with: |
|
What request is this failing on? If its the initialize request its likely there are additional required parameters in the configuration that get patched in. I would try adding |
Still erroring, this is the Debugger Protocol: Config: {
"type": "java",
"name": "Launch Current File",
"request": "launch",
"mainClass": "${file}",
"modulePaths": ["${folder}"],
"cwd": "${folder}",
"console": "internalConsole",
"env": {},
"stopOnEntry": false
}, |
|
Looks to be way past the initialize request. From the looks of it they are just not handling the configurationDone request correctly and treating the arguments as none optional. Try changing |
That did the trick. Now the command gets executed, but fails too... |
|
It's working now. Although I am still getting Settings: |
Error parsing message: com.google.gson.JsonSyntaxException: Expected a com.google.gson.JsonObject but was com.google.gson.JsonNull
|
Fixed that too. Since I changed the Protocol to |
|
@daveleroy How would an adapter add/set configuration variables? I would like to fetch classpath, mainclass,... with the Language Server because for example classpath can get very complicated on a big maven Project. |
Unlikely to break anything and is probably what vscode does despite the threads request not having any arguments specified in the spec https://microsoft.github.io/debug-adapter-protocol/specification |
You can adjust a configuration after the variables are expanded but before it is sent to the adapter using |
|
If you are talking about adding custom variables that can't currently be done and would need support added for it |
That should work :) |
|
Implemented auto-configuration of mainClass and classPaths allowing for a plug & play solution together with sublimelsp/LSP-jdtls#7 |
|
@daveleroy I get errors in the client. Protocol: |
|
@daveleroy The Java Language Server returns URIs like: leading to an empty view. JDT.LS can actually provide the contents of the class file, does Debugger support that the server resolves the content itself? |
|
The jar you are looking for is available at https://mvnrepository.com/artifact/com.microsoft.java/com.microsoft.java.debug.plugin and is exactly the same VSCode use to debug Java applications. |
|
@daveleroy @rwols The current implementation (together with sublimelsp/LSP-jdtls#7) does work, but uses a dirty hack to get the view created by the LSP-plugin. Ideally, I could await a future which does return the created view. |
|
You could just expose the request like we do for Also maybe that should be more generic since I think there are some other commands that need to get run as well to fetch configuration stuff. They seem to be also using # LSP side
class DebuggerJdtlsExecuteCommandCommand(LspWindowCommand):
session_name = 'jdtls'

self.handle_response(id, ValueError('Unable to find `jdtls` session'))
return
session.execute_command({"command": command, 'arguments': arguments}, False).then(lambda resp: self.handle_response(id, resp))
def handle_response(self, id, response):
if isinstance(response, Exception):
self.window.run_command('debugger_lsp_jdtls_excute_command_response', {'id': id, 'reject': str(response)})

if not future:
print("Hmm... unable to find a future port for this id")
return
if error := args.get('reject'):
future.set_exception(core.Error(error))

future.set_result(args.get('resolve'))

That should work. Then the only thing left is to move the special case into the Java adapter instead of the core module. |

@daveleroy The Java Adapter should work now. You might want to change the |

The configuration logic now uses a generic bridge which allows sending requests to the LSP. |

I might change that next week to only request if the user did not provide certain config option, by splitting in multiple methods. I should also use the correct main class in the checkProjectSettings command below.

@daveleroy Alright. Please do not release it until I fixed the user configuration overwrite. I'll open a follow up PR in the next few days. |
|
I'll notify you when I release the new LSP-jdtls version containing the necessary debug plugin and bridge. |
|
@LDAP Is there any way you can share a minimal java project that just prints hello world? I just can't get it done, and neither I can find more info of what I could try next. It can never find the main class and also:
I think I tried every permutation at this point. |

This PR adds Java support to the Debugger. LSP and LSP-jdtls are required for this adapter to work.
