gradle 6.x kotlin spring-boot jar发布失败，需要在gradle-kotlin-dsl中解决

问题描述

6.x版发行说明告诉我们 ing不起作用，因为默认的jar任务已被spring-boot插件禁用.

gradle 6.x release notes tells us that maven-publishing of boot-jars doesn't work because the default jar task is disabled by the spring-boot plugin.

一种解决方法是告诉Gradle上传什么.如果要上载bootJar，则需要配置传出配置以执行此操作:

A workaround is to tell Gradle what to upload. If you want to upload the bootJar, then you need to configure the outgoing configurations to do this:

configurations {
   [apiElements, runtimeElements].each {
       it.outgoing.artifacts.removeIf { it.buildDependencies.getDependencies(null).contains(jar) }
       it.outgoing.artifact(bootJar)
   }
}

不幸的是，我尝试将其转换为gradle-kotlin-dsl的所有尝试均失败:

unfortunately all my tries to translate this to gradle-kotlin-dsl fail:

configurations {
   listOf(apiElements, runtimeElements).forEach {
       it.outgoing.artifacts.removeIf { it.buildDependencies.getDependencies(null).contains(jar) }
       it.outgoing.artifact(bootJar)
   }
}

* What went wrong:
Script compilation errors:

it.outgoing.artifacts.removeAll { it.buildDependencies.getDependencies(null).contains(jar) }
                                                                             ^ Out-projected type 'MutableSet<CapturedType(out (org.gradle.api.Task..org.gradle.api.Task?))>' prohibits the use of 'public abstract fun contains(element: E): Boolean defined in kotlin.collections.MutableSet'

it.outgoing.artifacts.removeAll { it.buildDependencies.getDependencies(null).contains(jar) }
                                                                                      ^ Unresolved reference. None of the following candidates is applicable because of receiver type mismatch:
                                                                                                             public val TaskContainer.jar: TaskProvider<Jar> defined in org.gradle.kotlin.dsl
it.outgoing.artifact(bootJar)
                     ^ Unresolved reference. None of the following candidates is applicable because of receiver type mismatch: public val TaskContainer.bootJar: TaskProvider<BootJar> defined in org.gradle.kotlin.dsl

关于如何在Gradle Kotlin DSL中执行这种常规解决方法的想法吗?

any idea on how to do this groovy workaround in Gradle Kotlin DSL?

推荐答案

jar和bootJar似乎是Gradle任务.您可以像这样在Kotlin DSL中获得对任务的引用:

jar and bootJar seems to be Gradle tasks. You can get a reference to a task in Kotlin DSL like this:

configurations {
   listOf(apiElements, runtimeElements).forEach {
       // Method #1
       val jar by tasks
       it.outgoing.artifacts.removeIf { it.buildDependencies.getDependencies(null).contains(jar) }

       // Method #2
       it.outgoing.artifact(tasks.bootJar)
   }
}
