Cobertura + 为什么我不能运行 Cobertura 任务？

Question

我正在做一个多项目的gradle项目，主要build.gradle是这样的：

buildscript {
repositories {
    mavenLocal()
    mavenCentral()
}
    dependencies {
        classpath 'net.saliman:gradle-cobertura-plugin:2.2.4'
    }
}
plugins {
    id "org.sonarqube" version "2.2.1"
}
apply plugin: 'groovy'
apply plugin: 'cobertura'
def getVersionName = { ->
    def stdout = new ByteArrayOutputStream()
    exec {
        commandLine 'git', 'describe', '--tags', '--always'
        standardOutput = stdout
    }
    return stdout.toString().trim()
}
ext {
    springFrameworkVersion = '4.3.4.RELEASE'
}
subprojects {
    apply plugin: 'eclipse'
    apply plugin: 'idea'
    apply plugin: 'java'
    apply from: "${parent.projectDir.canonicalPath}/cobertura.gradle"
    sourceCompatibility = 1.8
    targetCompatibility = 1.8
    repositories {
        mavenCentral()
    }
    dependencies {
        compile("org.springframework:spring-context:${springFrameworkVersion}")
        testCompile("junit:junit:4.+")
        testCompile("org.springframework:spring-test:${springFrameworkVersion}")
    }
    jar {
        version = getVersionName()
    }
}
project(':projectA') {
}
project(':projectB') {
   dependencies {
            compile project(':projectA')
        }
    }
project(':projectC') {
    dependencies {
        compile project(':projectB')
    }
}
cobertura {
    coverageFormats = ['html', 'xml']
    coverageIgnoreTrivial = true
    coverageIgnores = ['org.slf4j.Logger.*']
    coverageReportDir = new File("$buildDir/reports/cobertura")
}

但是当我尝试使用 cobertura 任务运行 gradle 包装器时，它失败了，控制台输出为：

FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task ':instrument'.
> Could not resolve all dependencies for configuration ':cobertura'.
   > Cannot resolve external dependency net.sourceforge.cobertura:cobertura:2.0.3 because no repositories are defined.
     Required by:
         :main-project:unspecified

这是怎么回事？

Answer 1

就像错误消息告诉您的那样。

您已经在根项目中声明了对net.sourceforge.cobertura:cobertura:2.0.3的依赖（因为它没有明确添加，我猜 Gradle cobertura 插件隐式添加了它，它的文档可能应该告诉它），但您没有为根项目定义任何存储库。您只为构建脚本（用于解析 Gradle 插件和其他内容）和 subprojects 关闭中的所有子项目声明了存储库。也可以单独或使用闭包为根项目定义存储库allprojects您的构建应该可以正常工作，至少在这方面是这样。
