[완료] gradle이나 maven으로 소스 받고 싶을 때 어떻게 해야 하는지..

dependencies {
    // The production code uses the SLF4J logging API at compile time
    compile 'org.slf4j:slf4j-api:1.7.21'
 
    // Declare the dependency for your favourite test framework you want to use in your tests.
    // TestNG is also supported by the Gradle Test task. Just change the
    // testCompile dependency to testCompile 'org.testng:testng:6.8.1' and add
    // 'test.useTestNG()' to your build script.
    testCompile 'junit:junit:4.12'
 
 
    compile 'com.squareup.okhttp3:okhttp:3.4.1'
}
