"Variable references non-existent resource: ${container_loc:/path}"

[mattdibi]

Hello everyone,

as per title I'm getting the above error while setting up Neovim for my project.

I'm following the instruction available here.

jdtls configuration

  cmd = {
    'java',
    '-Declipse.application=org.eclipse.jdt.ls.core.id1',
    '-Dosgi.bundles.defaultStartLevel=4',
    '-Declipse.product=org.eclipse.jdt.ls.core.product',
    '-Dlog.protocol=true',
    '-Dlog.level=ALL',
    '-Xmx1g',
    '--add-modules=ALL-SYSTEM',
    '--add-opens', 'java.base/java.util=ALL-UNNAMED',
    '--add-opens', 'java.base/java.lang=ALL-UNNAMED',
    '-jar', '/home/mattia/.vscode/extensions/redhat.java-1.18.0-linux-x64/server/plugins/org.eclipse.equinox.launcher_1.6.400.v20210924-0641.jar',
    '-configuration', '/home/mattia/.vscode/extensions/redhat.java-1.18.0-linux-x64/server/config_linux',
    '-data', '/home/mattia/Desktop/kura/kura',
  },

  root_dir = require('jdtls.setup').find_root({'javaConfig.json'}),

  settings = {
    java = {
    }
  },

  init_options = {
    bundles = vim.split(vim.fn.glob("/home/mattia/Downloads/vscode-pde-0.8.0/server/*.jar"), "\n")
  },

If I set my target-definition file to the absolute paths everything works great

<?xml version="1.0" encoding="UTF-8" standalone="no"?><?pde version="3.8"?><target name="Kura Target Platform Equinox 3.16.0" sequenceNumber="47">
  <locations>
    <location path="/home/mattia/Desktop/kura/kura/target-definition/common/repository/plugins" type="Directory"/>
    <location path="/home/mattia/Desktop/kura/kura/target-definition/equinox_3.16.0/repository/plugins" type="Directory"/>
    <location path="/home/mattia/Desktop/kura/kura/target-definition/test-deps/repository/plugins" type="Directory"/>
  </locations>
</target>

but when I use the container_loc variable like so:

<?xml version="1.0" encoding="UTF-8" standalone="no"?><?pde version="3.8"?><target name="Kura Target Platform Equinox 3.16.0" sequenceNumber="47">
  <locations>
    <location path="${container_loc:/kura/target-definition/common/repository/plugins}" type="Directory"/>
    <location path="${container_loc:/kura/target-definition/equinox_3.16.0/repository/plugins}" type="Directory"/>
    <location path="${container_loc:/kura/target-definition/test-deps/repository/plugins}" type="Directory"/>
  </locations>
</target>

I get the Variable references non-existent resource error in the logs:

How can I configure jdt.ls such that the container_loc variable is correctly resolved?
