Am trying to setup a new repository for a multi module springBoot application using gradle (Kotlin DSL for build scripts)
As part of the same I am trying to declare generic configuration and dependencies needed for all subProjects. In doing so, I am trying to define sourceCompatility
for all child projects in the subprojects
block of parent build.gradle.kts
file
When I try to compile my project with above config then build is failing with the following exception
* What went wrong:
Extension with name 'java' does not exist. Currently registered extension names: [ext]
But if I move the line java.sourceCompatibility = org.gradle.api.JavaVersion.VERSION_11
to the child module’s build.gradle.kts
file then it is compiling successfully and application is coming up as expected.
I cannot understand what I’m missing here. Please help me understand this.
Parent build.gradle.kts
buildscript {
repositories {
mavenCentral()
}
}
plugins {
id("java")
id("idea")
id("war")
id("io.spring.dependency-management") version "1.0.9.RELEASE"
}
subprojects {
group = "com.company.example"
version = "0.0.1"
java.sourceCompatibility = org.gradle.api.JavaVersion.VERSION_11
repositories {
mavenCentral()
maven { url = uri("http://nexus.pentaho.org/content/groups/omni/") }
}
apply() {
plugin("java")
plugin("idea")
plugin("io.spring.dependency-management")
}
dependencies {
implementation("io.jsonwebtoken:jjwt-api:0.10.7")
implementation("io.jsonwebtoken:jjwt-impl:0.10.7")
implementation("com.auth0:java-jwt:3.10.3")
implementation(group= "org.mockito", name= "mockito-core", version= "3.1.0")

implementation("com.google.api.grpc:proto-google-common-protos:1.16.0")
implementation("com.google.api.grpc:grpc-google-longrunning-v1:0.1.8")
implementation(group= "org.apache.commons", name= "commons-lang3", version= "3.7")
implementation(group="com.google.guava", name= "guava", version= "29.0-jre")
implementation(group= "commons-io", name= "commons-io", version= "2.7")
testImplementation("org.junit.jupiter:junit-jupiter-api:5.3.1")
testRuntimeOnly("org.junit.jupiter:junit-jupiter-engine:5.3.1")
}
}
tasks.getByName<Test>("test") {
useJUnitPlatform()
}
Child build.gradle.kts
buildscript {
repositories {
mavenCentral()
}
}
plugins {
id("org.springframework.boot") version "2.3.0.RELEASE"
}
//java.sourceCompatibility = org.gradle.api.JavaVersion.VERSION_11
dependencies {
implementation("org.springframework.boot:spring-boot-starter-actuator")
implementation("org.springframework.boot:spring-boot-starter-web")
}
val jar by tasks.getting(Jar::class) {
manifest {
attributes["Main-Class"] = "com.company.example.module.ExampleApplication"
}
from(sourceSets.main.get().output)
dependsOn(configurations.runtimeClasspath)
from({
configurations.runtimeClasspath.get().filter { it.name.endsWith("jar") }.map { zipTree(it) }
})
}
settings.gradle.kts
for the project:
rootProject.name = "project_name"
include(":module_name")
P.S: I also tried using
configure<JavaPluginConvention>{
sourceCompatibility = org.gradle.api.JavaVersion.VERSION_11
}
But the same pattern is observed. Error thrown in this case is
* What went wrong:
Extension of type 'JavaPluginConvention' does not exist. Currently registered extension types: [ExtraPropertiesExtension]
