Kotlin import declaration is inserted incorrectly

已回答

E.g., I have:

import java.lang.StringBuffer

class Stuff {
    val cursor: StringBuffer
}

and I add a `java.io.File` component:

class Stuff {
    val cursor: StringBuffer
    val handle: File
}

then IntelliJ shows `File` in red and the context menu has the option to import the required declaration, but it inserts it like so:

import java.io.Fileimport java.lang.StringBuffer

class Stuff {
    val cursor: StringBuffer
    val handle: File
}

so I have to go back and reformat the import list. How can I stop that and make IntelliJ insert the required new line as well?

Hello,

Do you face this issue with Kotlin files only? Do you use default code style settings?

How can I find out if I'm using the default code style settings? I think I am, although I do use tab-indentation rather than spaces, so maybe not.

Curiously, with Java, an extra blank line is inserted:

import com.myTiM.V2.sql.SQLHandler;

import java.io.File;
import java.io.IOException;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
import javax.validation.constraints.NotNull;
import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.Logger;

public class CatalogueStoreImpl implements CatalogueStore {
    private static final Logger logger = LogManager.getLogger(CatalogueStoreImpl.class);
    private final Map<String,Object> storedMetadata = new HashMap<>();
    private final SQLHandler sql = new SQLHandler();
    private final String lastUpdateKey = "lastUpdateTimestamp";

    private final File thing = null;

    @Override
    public int getLastUpdateTimestamp() {

In that sample, I just added `private final File thing = null;` and IntelliJ inserted `import java.io.File;` with an extra blank line. Just to be clear, before the insertion, there was no blank line between `import com.myTiM.V2.sql.SQLHandler;` and `import java.io.IOException;`.

Looks like the *.kt files in the list of "Do not format" in your scheme - "Settings/Preferences | Editor | Code Style - Formatter". Delete this pattern and the problem should be fixed.

In Java there are "Import Layout" rules ("Settings/Preferences | Editor | Code Style | Java - Imports") which places blank line between all imports and "import java.*".

You are right; the *.kt pattern is there. This is a most regrettable solution. I found IntelliJ's reformatting of code extremely annoying, and was delighted to discover the possibility of disabling it. I think I'd rather accept having to reformat the automatically-generated import declarations, than fight IntelliJ's insistence on reformatting my code.

The solution for Java is acceptable; thank you.

Have you tried to set your rules for formatter? Or a lot of changes should be done?

Do you mean have I tried changing the rules so that the results of formatting are acceptable? No; I could try that.

You've answered the question, so thank you and we can close this ticket.
