The procedure I did when I prepared the environment of gradle + Java with VS Code (Windows 10)

I usually use JavaScript, so please let me know if there are any mistakes. Just in case, I will install the tools etc.!

(1) VSCode / gradle / Java installation

This time I will use chocolatey. Click here to install chocolatey (

choco install vscode -y
choco install gradle -y
choco install openjdk -y

(2) Create gradle project

First, create an appropriate folder and open it with VS Code.

mkdir sample-project
cd sample-project
code . #Open the current directory with vscode

From here it's OK to do it in the vscode terminal

gradle init 
#Option selection
Select type of project to generate:
  1: basic
  2: application
  3: library
  4: Gradle plugin
Enter selection (default: basic) [1..4] 2

Select implementation language:
  1: C++
  2: Groovy
  3: Java
  4: Kotlin
  5: Swift
Enter selection (default: Java) [1..5] 3 

Select build script DSL:
  1: Groovy
  2: Kotlin
Enter selection (default: Groovy) [1..2] 1

Select test framework:
  1: JUnit 4
  2: TestNG
  3: Spock
  4: JUnit Jupiter
Enter selection (default: JUnit 4) [1..4] 1

Project name (default: sample-project):
Source package (default: sample.project):

(3) Auto-completion

--Install an extension called Java Extension Pack in VSCode. (Don't forget to restart VS Code)

--Edit build.gradle


plugins {
    id 'java'
    id 'application'
    id 'eclipse' //Add this. To output the classpath for auto-completion.

repositories {

dependencies {
    implementation ''
    testImplementation 'junit:junit:4.12'

mainClassName = 'sample.project.App'

//Add below from here

//Measures against garbled characters
tasks.withType(JavaCompile) {
	options.encoding = "UTF-8"

//Have a single executable jar containing dependent libraries created.
jar {
    manifest { attributes 'Main-Class': mainClassName }
    from configurations.compileClasspath.collect { it.isDirectory() ? it : zipTree(it) }

--Output classpath

Be sure to run it after changing the dependencies.

gradle eclipse

You should now be able to do auto-completion.

(4) Code formatter (code shaping)

It's already in the Java Extension Pack, so you can do it with Shift + Alt + F.

If you want to make detailed settings, press F1 and enter ʻOpen Java formatter settingsto enter. After that, you will be asked to enter the path of the configuration file, but since it is not there, enter as it is. At the bottom right, you will see something like "'eclipse-formatter.xml' does not exist. Do you want to create it?", So pressYes`.

And now that eclipse-formatter.xml is created, let's set it as you like!

I am changing the following so that the line break code in the method chain etc. is not made into one line at the time of automatic formatting


<!--Change true to false-->
<setting id="org.eclipse.jdt.core.formatter.join_wrapped_lines" value="false"/>

Restart VS Code after setting
