Could not find com.squareup.picasso:picasso:2.5.2

问题:

I adding picasso dependencies but seem it not worked. I tried changing the version. But still useless.

This my build.gradle (module)

apply plugin: 'com.android.application'  android {     compileSdkVersion 23     buildToolsVersion '23.0.3'      defaultConfig {         applicationId "bhouse.travellist_starterproject"         minSdkVersion 21         targetSdkVersion 22         versionCode 1         versionName "1.0"     }     buildTypes {         release {             minifyEnabled false             proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'         }     } }  dependencies {     compile fileTree(dir: 'libs', include: ['*.jar'])     compile 'com.android.support:appcompat-v7:23.4.0'     compile 'com.android.support:recyclerview-v7:23.4.0'     compile 'com.android.support:cardview-v7:23.4.0'     compile 'com.android.support:palette-v7:23.4.0'     compile 'com.squareup.picasso:picasso:2.5.1'  } 

and this is my build.gradle (project)

// Top-level build file where you can add configuration options common to all sub-projects/modules. buildscript {     repositories {         jcenter()     }     dependencies {         classpath 'com.android.tools.build:gradle:2.1.0'          // NOTE: Do not place your application dependencies here; they belong         // in the individual module build.gradle files     } 

The error said:

Error:(27, 13) Failed to resolve: com.squareup.picasso:picasso:2.5.1 Show in File

Any help are welcome.

You need to add a section allprojects at the end of your main build.gradle that defines the repositories for the modules of your project:

allprojects {     repositories {         jcenter()     } } 

This will result in the following build.gradle:

buildscript {     repositories {         jcenter()     }     dependencies {         classpath 'com.android.tools.build:gradle:2.1.0'         // NOTE: Do not place your application dependencies here; they belong         // in the individual module build.gradle files     } }  allprojects {     repositories {         jcenter()     } }

According to their Github, you have to use MavenCentral to get their library so add this to your build.gradle(app) file:

repositories {     mavenCentral() } 

Resync and try again.

You need to add a maven repository from which Picasso can be downloaded. You can do that by adding this in your app module's build.gradle file:

repositories {     jcenter() } 

A good place would be just before your dependencies {} block.

In my case, I just set in the gradle.properties settings for https

systemProp.https.proxyHost=some.proxy.adress.com  systemProp.https.proxyPort=8080 

so in my case, gradle.properties will be:

systemProp.http.proxyHost=127.0.0.1 systemProp.http.proxyPort=8080 systemProp.https.proxyHost=127.0.0.1 systemProp.https.proxyPort=8080

Begins when I use the app,and just have a build (module) without build (app).

After I add Picasso library appears Error: (line, column) Failed to resolve: com.squareup.picasso: Picasso: 2.5.2 Show in File || Show in Project Structure dialog

as well as with the glide library

and the solution is as it says (DenisGL) is added allprojects follows:

allprojects {     repositories {         jcenter ()     } }
