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

Question

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.

Solution 1

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()
    }
}

Solution 2

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.

Solution 3

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

Solution 4

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.
