Large projects with multiple POM/maven files

[allancomar]

Hi all,

I work with a large project that has multiple pom/maven projects that are used, for example, a common library and multiple services that consume this library.

When I code using vscode I can change the library code and use/build on the service without needing to install the package on maven. When I am using nvim I need to clean install otherwise the service is not aware of the changes.

Is there any way I can set it up so I can have the same behaviour as vscode on nvim?

Thanks.

I am attaching a very simple sample. where I have a JLib that has some code and a JConsole that uses the code from the lib. if I change the code from the JLib the only way to reflect when debugging JConsole is to do a maven install on JLib.
jproject.tar.gz

Nice. it worked with lvim. I need to figure out what I configured wrong with my LSP on nvim. but now I know is working I can find my way around it. Thanks a lot for the help.

hi @mfussenegger, there is any way to print the root_dir loaded/associated with the lsp?
Thanks.

guess I am finally getting to the bottom. When I do this on lunarvim I get 1 jdtls attached to the buffer on the proper folder and 1 attached to nullls
when I do on neovim I got 2 jtdls attached:

Any ideas of what I am doing wrong on the configuration?
Thanks.

You can add print into the variable by chaing the plugin code.
Navigate into ~/.local/share/nvim/site/pack/paqs/start/nvim-jdtls (don't know if applies to all plugin managers)
Find where the variable is defined and print it. Here is a git patch you can apply

diff --git a/lua/jdtls/setup.lua b/lua/jdtls/setup.lua
index 07aa68a..3fb3fc8 100644
--- a/lua/jdtls/setup.lua
+++ b/lua/jdtls/setup.lua
@@ -205,6 +205,7 @@ function M.start_or_attach(config)
     or M.find_root({'.git', 'gradlew', 'mvnw'}, bufname)
     or vim.fn.getcwd()
   )
+  print(config.root_dir)
   config.handlers = config.handlers or {}
   config.handlers['language/status'] = config.handlers['language/status'] or status_callback
   config.handlers['workspace/configuration'] = config.handlers['workspace/configuration'] or configuration_handler

close and open nvim again, it should print it. You also can call :messages to see all printed content.

Or use:

:checkhealth vim.lsp

Or:

:lua =vim.lsp.get_active_clients({ name = "jdtls" }) to get full details

I guess I learned a little bit more about this. It seems that Microsoft has a jdtls extension to make this work on the project vscode-maven (https://github.com/microsoft/vscode-maven) that does what I am looking for.
Does anyone know how to extend jdtls with an extension? Never tried something like that. Thanks.

vscode-maven adds extra capabilities like searching for artifact/adding new dependencies.

It shouldn't be required to load an existing maven project. That functionality is built into eclipse.jdt.ls

thanks for the clarification. I did not had much time to invest on this search on the holidays, I will for sure try the root_dir latter this week. that might resolve all my problems, I will just need to figure out a way to manage different projects. Thanks again for the help.
