repositories {

dependencies {
    // Local packages
    compile files('libs/foo.jar')

    // Remote artifacts
    compile 'com.google.guava:guava:11.0.2'
}

android {
    ...
}

Complile

  • compile: main application
  • testCompile: test application
  • debugCompile: debug Build Type
  • releaseCompile: release Build Type.
  • <buildtype>Compile: (Ex: alphaCompile, betaCompile)

// Use Java Project lib1 with jar
dependencies {
    // 如果超過一個lib，那順序將會是很重要低
    compile project(':libraries:lib1')
    compile project(':libraries:lib2')
}

If you want to share code that accesses Android APIs or uses Android-style resources

these libraries cannot be regular Java project, they have to be Android Library Projects.
