Failed to resolve com.melnykov:floatingactionbutton:1.3.0 in gradle

I apologize if I am missing something obvious, but I recently converted my project from Eclipse to Android Studio (and Gradle) and am trying to add support for Floating Action Buttons using Melnykov's library, but Gradle cannot resolve it. I thought it was a simple matter of adding compile 'com.melnykov:floatingactionbutton:1.3.0' to my app's build.gradle file. Am I missing something or is the source not available to download or what? Thanks ahead of time.
My app's build.gradle file:
apply plugin: 'android'
dependencies {
compile 'com.android.support:support-v4:22.1.0'
compile files('libs/opencsv-3.1.jar')
compile 'com.android.support:appcompat-v7:22.1.0'
compile 'com.melnykov:floatingactionbutton:1.3.0'
}
android {
compileSdkVersion 22
buildToolsVersion "22"
sourceSets {
main {
manifest.srcFile 'AndroidManifest.xml'
java.srcDirs = ['src']
resources.srcDirs = ['src']
aidl.srcDirs = ['src']
renderscript.srcDirs = ['src']
res.srcDirs = ['res']
assets.srcDirs = ['assets']
}
// Move the tests to tests/java, tests/res, etc...
instrumentTest.setRoot('tests')
// Move the build types to build-types/<type>
// For instance, build-types/debug/java, build-types/debug/AndroidManifest.xml, ...
// This moves them out of them default location under src/<type>/... which would
// conflict with src/ being used by the main source set.
// Adding new build types or product flavors should be accompanied
// by a similar customization.
debug.setRoot('build-types/debug')
release.setRoot('build-types/release')
}
}
And the error I get is
Error:(6, 13) Failed to resolve:
com.makovkastar:floatingactionbutton:1.3.0

You have to add the repository from which gradle should download the aar.
repositories {
jcenter()
}
Without this part, gradle doesn't know where to find the dependencies.
The other libraries don't need the repo because they are local jars (they can be found in the lib folder):
compile files('libs/opencsv-3.1.jar')
or a local maven (provided with the sdk manager)
compile 'com.android.support:support-v4:22.1.0'
compile 'com.android.support:appcompat-v7:22.1.0'

The error seems to have been resolved after adding the jcenter repository like this. I don't fully understand it, but everything compiles now.
...
dependencies {
compile 'com.android.support:support-v4:22.1.0'
compile files('libs/opencsv-3.1.jar')
compile 'com.android.support:appcompat-v7:22.1.0'
compile 'com.melnykov:floatingactionbutton:1.3.0'
}
repositories {
jcenter()
}
...

Gradle DSL method not found: "classpath()"

I am working on an Android project, which used Gradle as mentioned below.
buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath 'com.android.tools.build:gradle:0.12.+'
}
}
allprojects {
repositories {
mavenCentral()
}
}
dependencies {
classpath 'com.android.tools.build:gradle:0.12.+'
compile fileTree(dir: 'libs', include: '*.jar')
compile project(':workspace:darkmoon:darul-android:vitamio:vitamio')
compile project(':Dev:adt-bundle-mac-x86_64:sdk:extras:google:google_play_services:libproject:google-play-services_lib')
}
android {
compileSdkVersion 19
buildToolsVersion "20.0.0"
sourceSets {
main {
manifest.srcFile 'AndroidManifest.xml'
java.srcDirs = ['src']
resources.srcDirs = ['src']
aidl.srcDirs = ['src']
renderscript.srcDirs = ['src']
res.srcDirs = ['res']
assets.srcDirs = ['assets']
}
// Move the tests to tests/java, tests/res, etc...
instrumentTest.setRoot('tests')
// Move the build types to build-types/<type>
// For instance, build-types/debug/java, build-types/debug/AndroidManifest.xml, ...
// This moves them out of them default location under src/<type>/... which would
// conflict with src/ being used by the main source set.
// Adding new build types or product flavors should be accompanied
// by a similar customization.
debug.setRoot('build-types/debug')
release.setRoot('build-types/release')
}
}
But when I build it, keep receiving this error: "Gradle DSL method not found", and it pointed to the
following line:
dependencies {
classpath 'com.android.tools.build:gradle:0.12.+'
compile fileTree(dir: 'libs', include: '*.jar')
compile project(':workspace:epsilonmobile:darul-android:vitamio:vitamio')
compile project(':Dev:adt-bundle-mac-x86_64:sdk:extras:google:google_play_services:libproject:google-play-services_lib')
}
Apologize if this question is a bit noob, I'm new to both Gradle and Android Studio

A classpath configuration is only available for buildscript dependencies. You need to get rid of the line classpath 'com.android.tools.build:gradle:0.12.+' in the top-level dependencies block. (Gradle plugins need to be declared under buildscript { dependencies { ... } }.)

In a gradle script, the buildscript is a special section where you can declare dependencies of the build script itself (i.e. binaries required by the build process).
The gradle build process is nothing more than a java process and so it supports normal classpath dependencies.
com.android.tools.build:gradle:0.12.+ identify a binary required by the build process (it contains code able to understand/execute the android section of the build script).
The android apk that will be build by this script don't needs the binary com.android.tools.build:gradle:0.12.+ to run on your android device (i.e. the apk is of course already build when it run on the device) : there is no reason to declare it again in the top level dependencies
(those are the dependencies required by your app)

Add Cardslib library To Android Studio 0.8.1

This is my first project using Android Studio so spare me if you find this question naive. I am trying to include the Cardslib library to my project in Android Studio (version 0.8.1). Initially I tried to include it by adding the following line in build.gradle:
compile 'com.github.gabrielemariotti.cards:library:1.7.3'
But it returned the following error (upon sync)
Error:Failed to find: com.github.gabrielemariotti.cards:library:1.7.3
The I tried to include the jar file by,
Downloading it from maven repository
Adding jar file to libs folder.
Adding following line in build.gradle
compile files('libs/library-1.7.3-sources.jar')`
Though gradle project sync without any error but I am not able to create simple cards i.e still not working for me.
I wanted the first method to work since Android Studio would then handle everything but I guess I am doing something horribly wrong.
[Edit] - Adding the build.gradle code
buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath 'com.android.tools.build:gradle:0.12.+'
}
}
apply plugin: 'android'
dependencies {
compile fileTree(dir: 'libs', include: '*.jar')
compile 'com.github.gabrielemariotti.cards:library:1.7.3'
}
android {
compileSdkVersion 19
buildToolsVersion '20.0.0'
sourceSets {
main {
manifest.srcFile 'AndroidManifest.xml'
java.srcDirs = ['src']
resources.srcDirs = ['src']
aidl.srcDirs = ['src']
renderscript.srcDirs = ['src']
res.srcDirs = ['res']
assets.srcDirs = ['assets']
}
// Move the tests to tests/java, tests/res, etc...
instrumentTest.setRoot('tests')
// Move the build types to build-types/<type>
// For instance, build-types/debug/java, build-types/debug/AndroidManifest.xml, ...
// This moves them out of them default location under src/<type>/... which would
// conflict with src/ being used by the main source set.
// Adding new build types or product flavors should be accompanied
// by a similar customization.
debug.setRoot('build-types/debug')
release.setRoot('build-types/release')
}
}

Add this block in your script to tell gradle where it can find the repo with libs.
repositories {
mavenCentral()
}
So your script will be something like this:
.......
apply plugin: 'android'
repositories {
mavenCentral()
}
dependencies {
compile fileTree(dir: 'libs', include: '*.jar')
compile 'com.github.gabrielemariotti.cards:library:1.7.3'
}
.......

Eclipse exported project in Android Studio and add remote dependency in build.gradle

I have exported my Android project in Eclipse as gradle build files, and imported in Android Studio.
I have updated my Android Studio today to v0.6.0 which built on June 05, 2014.
As a remote dependency I have added AppCompat to the dependencies which works fine as expected.
compile 'com.android.support:appcompat-v7:19.+'
But when I try to add other libraries such as SmoothProgressBar, actionbarsherlock, nineoldandroids and etc, it fails. When I run the app it shows following in Gradle Build tab:
Error:A problem occurred configuring root project 'MyApp'.
> Could not resolve all dependencies for configuration ':_debugCompile'.
> Could not find com.github.castorflex.smoothprogressbar:library:0.5.1.
Required by:
:MyApp:unspecified
And when I sync project with Gradle file, it shows following in Gradle Sync tab:
Error:com.github.castorflex.smoothprogressbar:library:0.5.1 (double-click here to find usages.)
I tried an empty new project and add remote dependency for mentioned libraries(Sherlock and etc) worked as expected. So I guess I missed something in build.gradle or any other solution?
buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath 'com.android.tools.build:gradle:0.11.+'
}
}
apply plugin: 'android'
dependencies {
compile fileTree(dir: 'libs', include: '*.jar')
compile 'com.github.castorflex.smoothprogressbar:library:0.5.1'
compile 'com.android.support:appcompat-v7:19.+'
}
android {
compileSdkVersion 19
buildToolsVersion "19.1.0"
sourceSets {
main {
manifest.srcFile 'AndroidManifest.xml'
java.srcDirs = ['src']
resources.srcDirs = ['src']
aidl.srcDirs = ['src']
renderscript.srcDirs = ['src']
res.srcDirs = ['res']
assets.srcDirs = ['assets']
}
// Move the tests to tests/java, tests/res, etc...
instrumentTest.setRoot('tests')
// Move the build types to build-types/<type>
// For instance, build-types/debug/java, build-types/debug/AndroidManifest.xml, ...
// This moves them out of them default location under src/<type>/... which would
// conflict with src/ being used by the main source set.
// Adding new build types or product flavors should be accompanied
// by a similar customization.
debug.setRoot('build-types/debug')
release.setRoot('build-types/release')
}
}

Add this code to your build.gradle
repositories {
mavenCentral()
}
Update to explain the answer:
To resolve your dependencies, you have to indicate in the gradle script which are the repositories to be used. You can use more repositories...
With the support libs (support and support-compact) it is not necessary, because the android plugin searches in your androidRepository and googleRepository downloaded with your SDK Manager.

Add GitHub library as dependency to Android Studio project

I am trying to implement ActionBar-PullToRefresh from https://github.com/chrisbanes/ActionBar-PullToRefresh/wiki/QuickStart-ABC. I just made the switch from Eclipse to Android Studio so I am totally new to AS and Gradle.
chrisbanes writes on the site:
The easiest way to add ActionBar-PullToRefresh to your project is via
Gradle, you just need to add the following dependency to your
build.gradle:
dependencies {
mavenCentral()
compile 'com.github.chrisbanes.actionbarpulltorefresh:extra-abc:+'
}
Does this mean that I don't have to download the library and Gradle takes care of it so that I always have the latest version? I just don't know where to put the above line. I have two gradle.build files one in my root that looks like:
// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath 'com.android.tools.build:gradle:0.8.+'
}
}
and the one in my project which looks like:
apply plugin: 'android'
dependencies {
compile fileTree(dir: 'libs', include: '*.jar')
compile 'com.android.support:support-v4:18.0.+'
compile 'com.android.support:appcompat-v7:18.0.+'
}
android {
compileSdkVersion 19
buildToolsVersion "19.0.1"
sourceSets {
main {
manifest.srcFile 'AndroidManifest.xml'
java.srcDirs = ['src']
resources.srcDirs = ['src']
aidl.srcDirs = ['src']
renderscript.srcDirs = ['src']
res.srcDirs = ['res']
assets.srcDirs = ['assets']
}
// Move the tests to tests/java, tests/res, etc...
instrumentTest.setRoot('tests')
// Move the build types to build-types/<type>
// For instance, build-types/debug/java, build-types/debug/AndroidManifest.xml, ...
// This moves them out of them default location under src/<type>/... which would
// conflict with src/ being used by the main source set.
// Adding new build types or product flavors should be accompanied
// by a similar customization.
debug.setRoot('build-types/debug')
release.setRoot('build-types/release')
}
}
Do I have to add a repository somewhere?

It will work when you put this line in your project build.gradle, in the dependencies section:
compile 'com.github.chrisbanes.actionbarpulltorefresh:extra-abc:+'
Also, add:
repositories {
mavenCentral()
}
So:
repositories {
mavenCentral()
}
dependencies {
compile fileTree(dir: 'libs', include: '*.jar')
compile 'com.android.support:support-v4:18.0.+'
compile 'com.android.support:appcompat-v7:18.0.+'
compile 'com.github.chrisbanes.actionbarpulltorefresh:extra-abc:+'
}
Gradle will download the needed resources automatically for you.

Use https://jitpack.io/
allprojects {
repositories {
jcenter()
maven { url "https://jitpack.io" }
}
}
dependencies {
compile 'com.github.User:Repo:Tag'
}

This is for Kotlin DSL (build.gradle.kts):
repositories {
// Other repositories...
maven("https://jitpack.io")
// OR maven { url = uri("https://jitpack.io") }
}
There are two places inside which you can insert the above code block:
The traditional way: inside top-level build.gradle.kts file
New way: inside a dependencyResolutionManagement { block in settings.gradle.kts file;
