nvim-dap, breakpoints are being ignored

[KDepayso]

Hello, I'm fairly new to NeoVim development and I've been trying to configure my setup for java development.

I've gotten most of my configurations set up, except I'm running into an issue where my breakpoints are being ignored. Other than that everything else is functioning as intended

Here's my ftplugin/java.lua file

local mason = require 'mason-registry'
local jdtls_path = mason.get_package('jdtls'):get_install_path()
local java_debug_path = mason.get_package('java-debug-adapter'):get_install_path()
local java_test_path = mason.get_package('java-test'):get_install_path()
local equinox_launcher_path = vim.fn.glob(jdtls_path .. '/plugins/org.eclipse.equinox.launcher_*.jar')
local workspace_dir = os.getenv("JAVA_WORKSPACE") .. package.config:sub(1, 1);
local root_dir = vim.fs.root(0, {".git", "mvnw", "gradlew", "pom.xml"})

local config_path = vim.fn.glob(jdtls_path .. '/config_win' )

local lombok_path = jdtls_path .. '/lombok.jar'


local bundles = {
    vim.fn.glob(
        java_debug_path
            .. '/extension/server/com.microsoft.java.debug.plugin-*.jar', 1
    ),
}

vim.list_extend(
    bundles,
    vim.split(vim.fn.glob(java_test_path .. '/extension/server/*.jar', 1), '\n')
)

local config = {

I haven't configured nvim-dap because I under the assumption that nvim-jdtls would handle it for me? Is there anything obvious I am missing here?

Thanks

yes if it didn't you wouldn't see the session starting and running.

Based on:

[ DEBUG ] 2024-09-21T22:54:07Z+0100 ] ...ppData/Local/nvim-data/lazy/nvim-dap/lua/dap/session.lua:1009 ]	3	{

      } }
  },
  command = "setBreakpoints",
  request_seq = 4,
  seq = 6,
  success = true,

}

The debug-adapter can't resolve the breakpoint. Which means either there's no code at line 8 where it can stop or there's some path mixup.

I managed to fix it by switching from NVChad to LazyVim, I would love to be able to say what was causing the issue, whether it was something wrong with NvChad or something else on my end but at least I'm happy now that my debugger is working as intended.
