Gradle task 'wrapper' not found in project ':subproject'

Question

I have root gradle project which needs to have a small Spring Boot subproject. This subproject will be deployed in the same pod as root project, so it needs to be built whenever root project is built. I tried by creating the following structure:

subproject/
├─ src/...
├─ build.gradle
settings.gradle

with the following contents:

settings.gradle:

pluginManagement {
    repositories {
        gradlePluginPortal()
    }
}

rootProject.name = 'root'


include 'subproject'

build.gradle:

plugins {
    id 'org.springframework.boot' version '2.7.0'
    id 'io.spring.dependency-management' version '1.0.11.RELEASE'
    id 'java'
}

group = 'com.demo'
version = '1.0.0-SNAPSHOT'
sourceCompatibility = '11'

repositories {
    mavenCentral()
}

dependencies {
    implementation 'org.springframework.boot:spring-boot-starter-web
    testImplementation 'org.springframework.boot:spring-boot-starter-test'
}

tasks.named('test') {
    useJUnitPlatform()
}

But when I refresh the project from within the IDEA, it shows Task 'wrapper' not found in project ':subproject'. What did miss? This subproject cannot exist by itself and shouldn't have a 'wrapper', it should be build by the root project.

$ ./gradlew -q projects
Root project 'root'
+--- Project ':subproject'

Gradle version: 6.8.3, Java version: 11

Answer 1

The problem actually does not exist. Everything is correct, except that IDEA added subproject as separate gradle project (I guess). So when I hit refresh, it could not be performed because IDEA was trying to find wrapper in the subproject. Simply saying, if you have such problem, check how many projects you have in your IDEA's Gradle view. In my case, there was two - root and subproject, the latter is unneeded.
