Question

私はlibraryprojectを含むプロジェクトを持っています。 は私の主な事業は次の依存関係があります。

dependencies { 
    compile fileTree(include: ['*.jar'], dir: 'libs') 
    compile project(':foundationclasses') 
    compile 'com.android.support:multidex:' 
    testCompile 'junit:junit:4.12' 
    compile 'com.android.support:appcompat-v7:23.3.0' 

    //NEUROTECHNOLOGY 
    compile files('libs/neurotec-media-android.jar') 
    compile files('libs/neurotec-media-processing-android.jar') 
    compile files('libs/neurotec-licensing-gui-android.jar') 
    compile files('libs/neurotec-licensing-android.jar') 
    compile files('libs/neurotec-gui-android.jar') 
    compile files('libs/neurotec-devices-android.jar') 
    compile files('libs/neurotec-core-android.jar') 
    compile files('libs/neurotec-cluster-android.jar') 
    compile files('libs/neurotec-biometrics-gui-android.jar') 
    compile files('libs/neurotec-biometrics-client-android.jar') 
    compile files('libs/neurotec-biometrics-android.jar') 
    compile files('libs/jna.jar') 
    compile files('libs/acra.jar') 

    //CREDENCE 
    compile files('libs/CredenceDeviceLib.jar') 

    //OTHER 
    compile 'cn.pedant.sweetalert:library:1.3' 
    compile 'com.github.fengdai:alertdialogpro-theme-material:0.2.6' 
    compile 'joda-time:joda-time:2.9.3' 
    compile 'com.wang.avi:library:1.0.2' 
    compile group: 'org.slf4j', name: 'slf4j-api', version: '1.7.12' 
} 

マイライブラリproject`sの依存関係：

dependencies { 
    compile fileTree(include: ['*.jar'], dir: 'libs') 
    compile 'com.google.guava:guava:18.0' 
    compile 'com.github.tony19:logback-android-classic:1.1.1-4' 
    compile group: 'org.slf4j', name: 'slf4j-api', version: '1.7.12' 
} 

gradlewアプリ：

私はすべてを試しましたが、このエラーを取り除くことはできません。アドバイスをいただければ幸いです！

Answer 1

slf4j APIは含まれていますが、実装はありません。使用するロガーに応じていくつかの異なる実装モジュールがあります。例えば

、あなたは簡単なロガーのための依存関係を追加することができます。

dependencies { 
    ... 
    runtime group: 'org.slf4j', name: 'slf4j-simple', version: '1.7.12' 
    ... 
} 

Answer 2

{} org.slf4j.LoggerFactoryクラスの船SLF4J-api.jarを持ちます。いくつかの不思議な理由により、slf4j-api.jarは実行時にアプリケーションの一部ではありません。
