[Gradle] 在build.gradle中添加本地包依赖

一直在Gradle中用的依赖包都是来自仓库，头一次添加本地包依赖。

buildscript {
    repositories {
        mavenCentral()
    }
}

apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'idea'

jar {
    baseName = 'HelloAlgs'
    version =  '0.1.0'
}

repositories {
    mavenCentral()
}

sourceCompatibility = 1.8
targetCompatibility = 1.8

dependencies {
  runtime files('libs/algs4.jar')
}

task wrapper(type: Wrapper) {
  gradleVersion = '2.3'
}
