Gradle failed to resolve library in Android Studio

问题

I want to include a library in Android Studio , but it displays error like below :

"Failed to resolve:com.lemonlab:expandable-button-menu:1.0.0"

How to fix this problem?

    apply plugin: 'com.android.application'

    android {
        compileSdkVersion 21
        buildToolsVersion '21.1.2'

        defaultConfig {
            applicationId "ayowes.com.newecampus"
            minSdkVersion 15
            targetSdkVersion 21
            versionCode 1
            versionName "1.0"
        }
        buildTypes {
            release {
                minifyEnabled false
                proguardFiles getDefaultProguardFile('proguard-android-ptimize.txt'), 'proguard-rules.txt'
            }
        }
    }

    dependencies {
        compile fileTree(dir: 'libs', include: ['*.jar'])
        compile 'com.android.support:appcompat-v7:21.0.3'
        compile 'com.google.android.gms:play-services:6.5.87'
        compile 'com.lemonlab:expandable-button-menu:1.0.0'
        compile files('libs/pinchzoom.jar')
    }

To be able to use a lib project you need to include it in your application's settings.gradle add:

include '..:ExpandableButtonMenu:library'

and then in your build.gradle add:

compile project(':..:ExpandableButtonMenu:library')

place ExpandableButtonMenu project along side your own (same folder)

see this How to build an android library with Android Studio and gradle? for more details.

You go File->Settings->Gradle Look at the "Offline work" inbox, if it's checked u uncheck and try to sync again I have the same problem and i try this , the problem resolved. Good luck !

回答3:

I had the same problem, the first thing that came to mind was repositories. So I checked the build.gradle file for the whole project and added the following code, then synchronized the gradle with project and problem was solved!

allprojects {
    repositories {
        jcenter()
    }
}

回答4:

Some time you may just need to add maven { url "https://jitpack.io" } in your allprojects block in project level build.gradle file.

Example:

allprojects {
    repositories {
        jcenter()
        maven { url "https://jitpack.io" }
    }
}

回答5:

solved by using "http://jcenter.bintray.com/" instead of "https://jcenter.bintray.com/"

repositories {
jcenter({url "http://jcenter.bintray.com/"})
}

回答6:

Check to see if your gradle is offline. Preferences-ProjectSettings-Gradle. If you're trying to add a library while offline, you'll see that error. Also, try Build-Clean, it may provide you with more detail.

回答7:

Well, it's co.lemonlabs, you have a typo in your build.gradle:

compile 'co.lemonlabs:expandable-button-menu:1.0.0'

回答8:

Try this

Clean project
Invalidate cache and restart studio
Check android SDK path is proper
Check is there any error in any of your resource file

回答9:

repositories {
    mavenCentral()
}

I added this in build.gradle, and it worked.

回答10:

i had the same problem, i added the following lines in build.gradle

allprojects {
repositories {
    jcenter()
    maven { url "https://jitpack.io" }

    maven {
        url 'http://dl.bintray.com/dev-fingerlinks/maven'
    }
    mavenCentral()
}

}

For me follwing steps helped.

It seems to be bug of Android Studio 3.4/3.5 and it was "fixed" by disabling:

File → Settings → Experimental → Gradle → Only sync the active variant
