Mimicking IntelliJ's sorting of imports

I'm working in a team of IntelliJ users and IntelliJ has a different import sorting order than jdtls, resulting in unnecessary code changes every time I run "Organize imports".

Is there a way to configure nvim-jdtls to organize the imports in the same order as IntelliJ?

Hi @simon1573.

We had a similar problem at my workplace with Visual Studio Code & IntelliJ users.

You can change the import order using the java.completion.importOrder setting.

For nvim-jdtls, you can define this in Lua like:

config.settings = {
  java = {
    completion = {
      importOrder = {
        "java",
        "javax",
        "org",
        "com"
      }
    }
  }
}

See @mfussenegger's sample configuration for more context:

See https://github.com/redhat-developer/vscode-java#supported-vs-code-settings for more details on this configuration option, and others that are available.

There's also static imports to consider.

I believe JDTLS will layout static imports separately with no way to change this behavior, but this is an option in IntelliJ.

See Intellij Import Layout options:

Layout static imports separately: if this checkbox is selected, all static imports will be kept in a separate section. Otherwise, all import statements will be sorted according to the specified layout rules.

I believe IntelliJ has a similar ability to specify the import order somewhere.

I would reach out to your IntelliJ co-workers to determine what IntelliJ's default import order is, or have everyone define the same order.
