Add formatter options to format multiple parameters with new lines

[slezhnin]

I'd like my code to be formatted with new lines for annotation, constructor or method call or declaration with multiple parameters.

For instance:

@Parameter(
    in = ParameterIn.PATH,
    name = "resourceName",
    description = "Resource Name",
    required = true,
    example = "1",
    schema = @Schema(type = SchemaType.STRING, minLength = 1)
)

Current formatter makes a one-liner like this:

@Parameter(in = ParameterIn.PATH, name = "resourceName", description = "Resource Name", required = true, example = "1", schema = @Schema(type = SchemaType.STRING, minLength = 1))

So the formatter should insert new line after the opening brace and comma and before the closing brace.

Environment

• Operating System: MacOs Monterey 12.3
• JDK version: openjdk version "11.0.15" 2022-04-19
• Visual Studio Code version: 1.67.2
• Java extension version: v1.6.0

Steps To Reproduce

1. Add annotation with multiple parameters
2. Format the code
3. In my current formatter version it should compact it to one line

Current Result

@Parameter(in = ParameterIn.PATH, name = "resourceName", description = "Resource Name", required = true, example = "1", schema = @Schema(type = SchemaType.STRING, minLength = 1))

Expected Result

@Parameter(
    in = ParameterIn.PATH,
    name = "resourceName",
    description = "Resource Name",
    required = true,
    example = "1",
    schema = @Schema(type = SchemaType.STRING, minLength = 1)
)

You could try what's referenced in eclipse-jdtls/eclipse.jdt.ls#1717 (comment) . There are many different formatting options supported.

I found that I needed to set it to org.eclipse.jdt.core.formatter.alignment_for_arguments_in_annotation=49 (instead of 48) to force the setting. Otherwise it's optional.

You could also create your own formatter as described in https://github.com/redhat-developer/vscode-java/wiki/Formatter-settings . The option would be <setting id="org.eclipse.jdt.core.formatter.alignment_for_arguments_in_annotation" value="49"/>
