Visual Studio Code java format document braces new line

问题

How can I get Visual Studio Code to format Java documents with braces in a new like?

i.e:

This

public static void main(String args[]) {
}

To this

public static void main(String args[])
{
}

Edit: Yikes!! Just remember .vscode/extensions folder. I went in there then /ryannaddy.vscode-format-0.0.6/package.json and changed format.newLine to true. Thanks for the help. So happy!!

To solve this using "Language Support for Java(TM) by Red Hat" you can use an Eclipse formatter file. This allows you to specify brace position very specifically for each scenario. For example, formatting.xml showcasing all "next line" settings:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<profiles version="12">
    <profile kind="CodeFormatterProfile" name="style" version="12">
        <setting id="org.eclipse.jdt.core.formatter.brace_position_for_anonymous_type_declaration" value="next_line"/>
        <setting id="org.eclipse.jdt.core.formatter.brace_position_for_method_declaration" value="next_line"/>
        <setting id="org.eclipse.jdt.core.formatter.brace_position_for_block" value="next_line"/>
        <setting id="org.eclipse.jdt.core.formatter.brace_position_for_constructor_declaration" value="next_line"/>
        <setting id="org.eclipse.jdt.core.formatter.brace_position_for_lambda_body" value="next_line"/>
        <setting id="org.eclipse.jdt.core.formatter.brace_position_for_enum_declaration" value="next_line"/>
        <setting id="org.eclipse.jdt.core.formatter.brace_position_for_block_in_case" value="next_line"/>
        <setting id="org.eclipse.jdt.core.formatter.brace_position_for_annotation_type_declaration" value="next_line"/>
        <setting id="org.eclipse.jdt.core.formatter.brace_position_for_switch" value="next_line"/>
        <setting id="org.eclipse.jdt.core.formatter.brace_position_for_array_initializer" value="next_line"/>
        <setting id="org.eclipse.jdt.core.formatter.brace_position_for_enum_constant" value="next_line"/>
        <setting id="org.eclipse.jdt.core.formatter.brace_position_for_type_declaration" value="next_line"/>
    </profile>
</profiles>

Valid values are next_line, next_line_shifted, next_line_on_wrap and end_of_line.

And then in your settings.json for Visual Studio Code:

{
    "java.format.settings.url": "/formatting.xml",
    "java.format.settings.profile": "style"
}

See this documentation for some usage details.

Launch VS Code Quick Open (Ctrl+P), paste the following command, and press enter.
ext install vscode-format
Visual Studio Code Format will allow you to format most of your code documents. The formatting is triggered by running your format command: editor.action.format

Place your braces on the same line or the next line:
{
    "newLine": {
        "brace": true
    }
}

You don't need any extension to make this work with Visual Studio Code v. 1.23.1 to format opening curly braces in a new line.

For Java Script and Type Script:

Go to File => Preferences => Settings

Copy and paste the following lines inside your User Settings:

"javascript.format.placeOpenBraceOnNewLineForControlBlocks": true, 
"javascript.format.placeOpenBraceOnNewLineForFunctions": true,

"typescript.format.placeOpenBraceOnNewLineForControlBlocks": true,
"typescript.format.placeOpenBraceOnNewLineForFunctions": true,

Save
Done

In my case, my formatter setting is in .setting/org.eclipse.jdt.core.prefs.

Actually, this article works, I've tested by creating a new project for comparison. I couldn't understand why is that worked on that new project, while my main project didn't. So, I compared any project settings that applied to each project, and I found that difference in .setting/org.eclipse.jdt.core.prefs file.

Location of .setting/org.eclipse.jdt.core.prefs

My new project has only a compiler setting in that file, while my main project has compiler + formatter setting, that's why setting in JSON file couldn't apllied.

My solution is to change the value of formatter setting in that file with the same value from my exported xml formatter (I got my formatter XML exported from eclipse). Thanks.

This is my new project content of .setting/org.eclipse.jdt.core.prefs:

eclipse.preferences.version=1
org.eclipse.jdt.core.compiler.codegen.methodParameters=generate
org.eclipse.jdt.core.compiler.codegen.targetPlatform=1.8
org.eclipse.jdt.core.compiler.compliance=1.8
org.eclipse.jdt.core.compiler.problem.enablePreviewFeatures=disabled
org.eclipse.jdt.core.compiler.problem.forbiddenReference=warning
org.eclipse.jdt.core.compiler.problem.reportPreviewFeatures=ignore
org.eclipse.jdt.core.compiler.processAnnotations=enabled
org.eclipse.jdt.core.compiler.release=disabled
org.eclipse.jdt.core.compiler.source=1.8

and this is what's inside my main project:

...    
org.eclipse.jdt.core.compiler.problem.enumIdentifier=error
org.eclipse.jdt.core.compiler.problem.forbiddenReference=warning
org.eclipse.jdt.core.compiler.problem.reportPreviewFeatures=ignore
org.eclipse.jdt.core.compiler.processAnnotations=enabled
org.eclipse.jdt.core.compiler.release=disabled
org.eclipse.jdt.core.compiler.source=1.8
org.eclipse.jdt.core.formatter.align_assignment_statements_on_columns=false
org.eclipse.jdt.core.formatter.align_fields_grouping_blank_lines=2147483647
org.eclipse.jdt.core.formatter.align_type_members_on_columns=false
org.eclipse.jdt.core.formatter.align_variable_declarations_on_columns
...
