Gradle中的任务和插件冲突(未能应用插件[class'org.Gradle.langu…)

我试图从运行任务 build.gradle 使用以下命令:

gradle footype

但是,生成失败,并显示了我要修复的两条错误消息:

> Configure project : 
The Task.leftShift(Closure) method has been deprecated and is scheduled to 
be removed in Gradle 5.0. Please use Task.doLast(Action) instead.

* What went wrong:
An exception occurred applying plugin request [id: 'java']
> Failed to apply plugin [class         
'org.gradle.language.base.plugins.LifecycleBasePlugin']
   > Declaring custom 'assemble' task when using the standard Gradle 
lifecycle plugins is not allowed.

这是密码 建筑格拉德尔 文件:

plugins{
  id "com.gradle.build-scan" version "1.10.2"
  id "org.arquillian.spacelift" version "1.0.0-alpha-17"
  id "java"
}

group 'k'
version '1.0-SNAPSHOT'

sourceCompatibility = 1.8

repositories {
  mavenCentral()
}

task fooType {
  doLast {
    def foo = "bar"
    println "$foo + foo = ${foo + "foo"}"
  }
}

我搜索了其他帖子,它们似乎都提到了一个名为clean()的任务,但它没有出现在我的代码中,所以我想知道问题出在哪里。

非常感谢你阅读这篇文章。
