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

Question

gradle 6.x release notes告诉我们maven-publish-jar的启动不起作用，因为默认的jar任务被spring-boot插件禁用了。

一种解决方法是告诉Gradle上传什么。如果您要上传bootJar，则需要配置传出配置来执行此操作：

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

不幸的是，我所有将其转换为gradle-kotlin-dsl的尝试都失败了：

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

有没有关于如何在Gradle Kotlin DSL中做这个出色的变通方法的想法？

Answer 1

jar和bootJar似乎是Gradle任务。您可以在Kotlin DSL中获得对任务的引用，如下所示：

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)
   }
}
