GradleのCoveturaPlugin設定

apply plugin: 'java'
apply plugin: 'groovy'

buildscript {
  repositories {
    mavenCentral()
  }
  dependencies {
    classpath "net.saliman:gradle-cobertura-plugin:2.0.0"
  }
  buildDir = 'target'
}

apply plugin: 'cobertura'

group = 'org.me'
version = '0.1'
sourceCompatibility = 1.7
targetCompatibility = 1.7
def isOnJenkins = System.properties.containsKey('jenkins')

cobertura.coverageFormats = (isOnJenkins)?['xml']:['html']

Jenkinsの設定でswitchesに-Djenkinsと設定しておくとxmlファイルでレポートされる。
