Gradle kotlin in Gradle5.2 Unresolved reference: dependtest - spring-boot

Question

A multi module project with Kotlin source code, which used to work, stops working after upgrading to Gradle 5.2, because the Kotlin classes from the compile project('depend-test') dependency are not found.
Attempted to change plugin version
already viewed https://github.com/gradle/gradle/issues/8980
i defind Test class in project('depend-test')
object Test {
const val test = "123"
}
i want to use Test class in project('test-test')
package com.example.test.controller
import com.example.dependtest.Test
import org.slf4j.LoggerFactory
import org.springframework.web.bind.annotation.GetMapping
import org.springframework.web.bind.annotation.RequestMapping
import org.springframework.web.bind.annotation.RestController
#RestController
#RequestMapping
class TestController {
private val log = LoggerFactory.getLogger(TestController::class.java)
#GetMapping(value = ["/test"])
fun test() {
log.info(Test.test)
}
}
when i want to build project('test-test') to jar where i used gradle bootJar。 I get this error:
> Task :test-test:compileKotlin FAILED
e: /Users/houshuai/Documents/dev/demo/test/test-test/src/main/kotlin/com/example/test/controller/TestController.kt: (3, 20): Unresolved reference: dependtest

Expected Behavior
The Kotlin classes in the compile project('depend-test') dependency should be found.
Current Behavior
The Kotlin classes in the compile project('depend-test') dependency are not found:

Answer 1

Try adding this to your build.gradle file
bootJar {
enabled = false
}
jar {
enabled = true
}
Just in case someone else comes across this problem.

Answer 2

I created two modules, test-test and depend-test.
The depend-test project is test-test 's dependency.
I tried to call the parameters of depend-test, but it failed to compile and package.
Env
gradle-5.2.1
Kotlin 1.3.31
Springboot 2.1.4
java 1.8
step one
Edit settings.gradle
rootProject.name = 'demo'
include ":depend-test"
include ":test-test"
project(":depend-test").projectDir = file("depend/depend-test")
project(":test-test").projectDir = file("test/test-test")
I used the 1.3.31 version of the kotlin plug-in. The build.gradle file reads as follows
buildscript {
ext {
kotlinVersion = '1.3.31'
}
repositories {
mavenCentral()
maven { url 'http://maven.aliyun.com/nexus/content/groups/public/'}
maven { url "https://plugins.gradle.org/m2/" }
}
dependencies {
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlinVersion"
classpath "org.jetbrains.kotlin:kotlin-allopen:$kotlinVersion"

}
allprojects {
apply plugin: 'idea'
apply plugin: 'kotlin'

}
}
subprojects {

apply plugin: 'java'

}
compileTestKotlin {

jvmTarget = '1.8'
}
}
dependencies {

testImplementation 'org.springframework.boot:spring-boot-starter-test'
}
}
dependencies {
subprojects.forEach {
archives(it)
}
}
repositories {
mavenCentral()
}
step two
build jar for test-test project ,I used two ways, but the results were the same.
terminal use cmd is ./gradlew :test-test:bootJar
user IDEA gradle tool
result
The class file written by kotlin in the submodule cannot be found.
I do not know if the lack of necessary plug-ins caused the failure to package properly.
