gradle 多工程apply plugin問題

最近用gradle編譯spring cloud的項目，在父工程加入

subprojects {
    apply plugin: 'java'
    apply plugin: 'org.springframework.boot'
    ....

的時候,遇到了一個比較奇怪的問題

gradle subprojects plugin with id not found

后來找到一個臨時的方案拣宰，現(xiàn)在記錄在這里
假如我有兩個項目，一個是eureka-service吻谋， 一個是eureka-client，前者代表用eureka構(gòu)建的eureka的服務(wù)器现横，后者代表使用eureka構(gòu)建的客戶端漓拾，兩者其實有很多共同的build.gralde 元素阁最，最直白的就是對于spring boot等的plugin的引用
原始的erueka-client的build.gradle 文件

buildscript {
    ext {
        springBootVersion = '1.5.6.RELEASE'
    }
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
    }
}

apply plugin: 'java'
apply plugin: 'idea'
apply plugin: 'org.springframework.boot'

jar {
    baseName = 'eureka-client'
    version = '0.0.1-SNAPSHOT'
}
sourceCompatibility = 1.8
targetCompatibility = 1.8

repositories {
    mavenCentral()
}

dependencyManagement {
    imports {
    //  mavenBom 'org.springframework.cloud:spring-cloud-dependencies:Camden.SR5'
        mavenBom 'org.springframework.cloud:spring-cloud-dependencies:Dalston.SR4'
    }
}

dependencies {
    compile('org.springframework.cloud:spring-cloud-starter-eureka')
    compile('org.springframework.boot:spring-boot-starter-web')
    testCompile('org.springframework.boot:spring-boot-starter-test')
    testCompile('org.springframework.cloud:spring-cloud-starter-eureka-server')
}

原始的eureka-service的gradle文件

buildscript {
    ext {
        springBootVersion = '1.5.6.RELEASE'
    }
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
    }
}

apply plugin: 'java'
apply plugin: 'idea'
apply plugin: 'org.springframework.boot'

jar {
    baseName = 'eureka-service'
    version = '0.0.1-SNAPSHOT'
}
sourceCompatibility = 1.8
targetCompatibility = 1.8

repositories {
    mavenCentral()
}


dependencyManagement {
    imports {
    //mavenBom 'org.springframework.cloud:spring-cloud-dependencies:Camden.SR5'
        mavenBom 'org.springframework.cloud:spring-cloud-dependencies:Dalston.SR4'
    }
}

dependencies {
    compile('org.springframework.cloud:spring-cloud-starter-eureka-server')
    testCompile('org.springframework.boot:spring-boot-starter-test')
}

可以看到，除了dependencies這部分骇两，我們可以單獨存放速种，其他的，都是一樣的低千，我們完全可以放到父工程的gradle文件里配阵，于是就要這么辦，在父工程的build.gradle中

subprojects {
    buildscript {
    ext {
        springBootVersion = '1.5.6.RELEASE'
    }
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
    }
    }
    apply plugin: 'java'
    apply plugin: 'org.springframework.boot'

    sourceCompatibility = 1.8
    targetCompatibility = 1.8

    repositories {
        mavenCentral()
    }

    dependencyManagement {
        imports {
            //  mavenBom 'org.springframework.cloud:spring-cloud-dependencies:Camden.SR5'
            mavenBom 'org.springframework.cloud:spring-cloud-dependencies:Dalston.SR4'
        }
    }
}

這時候栋操，問題就來了闸餐，會報錯饱亮，提示說找不到plugin java和org.springframework.boot等矾芙，查了網(wǎng)頁才知道要這么搞

buildscript {
    ext {
        springBootVersion = '1.5.6.RELEASE'
    }
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
    }
}

subprojects {
    apply plugin: 'java'
    apply plugin: 'org.springframework.boot'

    sourceCompatibility = 1.8
    targetCompatibility = 1.8

    repositories {
        mavenCentral()
    }

    dependencyManagement {
        imports {
            //  mavenBom 'org.springframework.cloud:spring-cloud-dependencies:Camden.SR5'
            mavenBom 'org.springframework.cloud:spring-cloud-dependencies:Dalston.SR4'
        }
    }
}

感覺是在subprojects 里不能放置buildscript的東西，估計還是gradle生命周期的問題近上。
