Gradle-使用带有闭包作为参数的插件方法的语法错误 [英] Gradle - Syntax error using plugin method with closure as argument

问题描述

下面是两个任务 hello & build.gradle 中的 printProperties :

Below are two tasks hello & printProperties in build.gradle:

task('hello', {
            description("Hey student! Run this one :D")
            group("Our demo")
            doLast({println("Hello World!")})
            }
     )

plugins({
    id('java')
})

ext({
    springVersion = "3.1.0.RELEASE"
    emailNotification = "[e-mail]"
})

sourceSets.all({ ext.purpose = null })

sourceSets({
    main({
        purpose = "production"
    })
    test({
        purpose = "test"
    })
    plugin({
        purpose = "production"
    })
})

task('printProperties', {
    doLast({
        println(springVersion)
        println(emailNotification)
        sourceSets.matching({ it.purpose == "production" }.each({ println it.name }))
    })
})

出现错误的

---

that gives error:

> startup failed:
  build file '/../../build.gradle': 8:
only buildscript {} and other plugins {} script blocks are allowed before plugins {} blocks, no other statements are allowed

---

为什么 plugins({id('java')})给出常规脚本语法错误?

---

Why plugins({id('java')}) give groovy scripted syntax error?

无论何时编写build.gradle脚本并使用新插件脚本块，您需要将其作为文件的第一个块.唯一的此规则的例外是其他插件块或特殊buildScript块，该块必须始终排在第一位.

Whenever you write a build.gradle script and use the new plugins script block, you need to put it as first block in the file. The only exceptions from this rule are other plugins blocks or the special buildScript block, which always must go first.
