Gradle不会自动将jar添加到项目中

Question

Here is my build.gradle file when I compile it always says 'cannot find symbol class HtmlFetcher' which is inside the de.jetwick.snacktory dependency

jar file of snacktory library is downloaded into local gradle cache but it is not including it into project. what might be a problem?

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.7.+'
    }
}
apply plugin: 'android'

repositories {
    mavenCentral()
    maven {url "https://github.com/karussell/mvnrepo/raw/master/releases"}
}

android {
    compileSdkVersion 18
    buildToolsVersion "18.0.1"

    defaultConfig {
        minSdkVersion 15
        targetSdkVersion 19
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            runProguard false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
        }
    }
}

dependencies {
    compile 'com.android.support:support-v4:+'
    compile 'de.jetwick:snacktory:1.1'
    compile fileTree(dir: 'libs', include: '*.jar')
}

Answer 1

Upgrade to Android Studio 0.4.3. There are bugs with adding dependencies that have been fixed since 0.4.0.

Answer 2

compile fileTree(dir: 'libs', include: '*.jar')

That is the same line I use to compile my libs directory. I'm not sure if it's the version, as I've been using the above gradle line since 0.3 or so, and it's worked fine.

The only other thing to check would be the location of your libs folder.

Your libs folder needs to be inside of your Module.

Android studio projects are the same as IntelliJ projects meaning that the directory structure should be: ProjectName/ModuleName/libs

That means you need a libs directory on the same level as your src directory and build.gradle file. Double check it's in the right location.
