Question

我有一个Android项目（Gradle），我需要包含Joda Time和Commons IO个库。这是我的Gradle文件：

apply plugin: 'android-library'
apply plugin: 'android-test'

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.10.+'
        classpath 'org.robolectric.gradle:gradle-android-test-plugin:0.10.+'
    }
}

dependencies {
    repositories {
        mavenCentral()
        maven {
            url 'https://oss.sonatype.org/content/repositories/snapshots/'
        }
    }

    androidTestCompile 'com.google.guava:guava:14.0.1',
            'com.squareup.dagger:dagger:1.1.0',
            'org.hamcrest:hamcrest-integration:1.1',
            'org.hamcrest:hamcrest-core:1.1',
            'org.hamcrest:hamcrest-library:1.1'

    androidTestCompile('junit:junit:4.11') {
        exclude module: 'hamcrest-core'
    }
    androidTestCompile 'org.mockito:mockito-all:1.9.5'

    androidTestCompile('org.robolectric:robolectric:2.3') {
        exclude module: 'classworlds'
        exclude module: 'maven-artifact'
        exclude module: 'maven-artifact-manager'
        exclude module: 'maven-error-diagnostics'
        exclude module: 'maven-model'
        exclude module: 'maven-plugin-registry'
        exclude module: 'maven-profile'
        exclude module: 'maven-project'
        exclude module: 'maven-settings'
        exclude module: 'nekohtml'
        exclude module: 'plexus-container-default'
        exclude module: 'plexus-interpolation'
        exclude module: 'plexus-utils'
        exclude module: 'wagon-file'
        exclude module: 'wagon-http-lightweight'
        exclude module: 'wagon-http-shared'
        exclude module: 'wagon-provider-api'
    }
    androidTestCompile 'com.squareup:fest-android:1.0.+'

    compile files('./libs/joda-time-2.4.jar')
    compile files('./libs/commons-io-2.1.jar')
    compile files('./libs/jackson-annotations-2.0.2.jar');
    compile files('./libs/jackson-core-2.0.2.jar');
    compile files('./libs/jackson-databind-2.0.2.jar');
    compile files('./libs/scribe-1.2.3.jar');
}

android {
    packagingOptions {
        exclude 'LICENSE.txt'
        exclude 'META-INF/LICENSE'
        exclude 'META-INF/LICENSE.txt'
        exclude 'META-INF/NOTICE'
    }
    compileSdkVersion 19
    buildToolsVersion "19.0.3"

    defaultConfig {
        versionName "1.0"
        versionCode 1
    }

    sourceSets {
        main {
            manifest.srcFile 'AndroidManifest.xml'
            java.srcDirs = ['src/main/java']
            res.srcDirs = ['res']
        }

        androidTest {
            java.srcDirs = ['src/test/java']
        }
    }

    lintOptions {
        abortOnError false
    }
}

问题在于我无法编译应用程序，出现以下错误：

Error:Gradle: Execution failed for task ':App:packageDebug'.
> Duplicate files copied in APK META-INF/LICENSE.txt
    File 1: <Path>/unspecified/libs/commons-io-2.1.jar
    File 2: <Path>/unspecified/libs/commons-io-2.1.jar

正如您所看到的，我已将exclude 'META-INF/LICENSE.txt'行放入build.gradle中，但问题仍然存在。如果我删除了commons-io库依赖项，那么所有编译都会完美。

谢谢，

您需要排除LICENSE.txt和NOTICE.txt：

android {
    //code

    packagingOptions {
        exclude 'META-INF/NOTICE.txt'
        exclude 'META-INF/LICENSE.txt'
    }
}

dependencies {
    compile 'joda-time:joda-time:2.3'
    compile 'commons-io:commons-io:2.4'
}

这对我有同样的错误。 也请注意版本。

在Android项目中包含Joda Time和Common IO库时，在APK中复制的重复文件
