As the title said, I want to create an new module in Spring-Project to debug source code to learn.

So i create a new module named spring-z-simple look like this

And here is my gradle file look like

plugins {
    id 'java'
}

group = 'org.springframework'
version = '6.2.0-SNAPSHOT'

repositories {
    mavenCentral()
}

dependencies {
    api(project(":spring-context"))
    testImplementation platform('org.junit:junit-bom:5.10.0')
    testImplementation 'org.junit.jupiter:junit-jupiter'
}

test {
    useJUnitPlatform()
}

After i build project successfully,I try to code. But i get this error in idea when i’m typing

error screenshot

And i also can’t find ApplicationContext class in spring-context module, but i have already add dependency in gradle file

I’m confirm that i set the right jdk for this project and this module

And in gradle tool window, my module spring-z-simple has no dependencies of spring-context

I have never use gradle before, So what should i do?
