Segalanya bekerja dengan baik pagi ini sebelum saya memperbarui Android Studio. Ada ide?

EDIT: Saya bisa memperbaikinya untuk sementara waktu dengan menjalankan perintah like

zip -d spring-android-core-1.0.1.RELEASE.jar META-INF/notice.txt

sampai semua kesalahan duplikat hilang.

Pada Android Studio versi 0.8.14

Anda harus menambahkan:

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

ke build.gradlefile Anda .

Sejarah:

Menurut komentar 14 dalam bug ini: https://issuetracker.google.com/issues/36982149#comment14 ini adalah bug di v0.7.0 dari plugin Android Gradle, dan akan segera diperbaiki di 0.7.1.

Berikut adalah catatan dari bug tentang penambahan untuk 0.7.1:

0.7.1 keluar dengan perbaikan untuk ini.

DSL untuk mengecualikan file adalah:

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

Anda dapat menambahkan pernyataan kecualikan sebanyak yang Anda inginkan. Nilai adalah jalur arsip. Belum ada wildcard atau dukungan glob.

Nama file "LICENSE.txt" dan "NOTICE.txt" peka huruf besar-kecil. Silakan coba dengan "license.txt" dan "notice.txt" juga.

Dalam kasus saya, saya harus memasukkan beberapa pengecualian tambahan. Tampaknya tidak menyukai ekspresi Reguler yang akan menjadikan ini garis satu bagus.

android {
    packagingOptions {
        exclude 'META-INF/DEPENDENCIES.txt'
        exclude 'META-INF/DEPENDENCIES'
        exclude 'META-INF/dependencies.txt'
        exclude 'META-INF/LICENSE.txt'
        exclude 'META-INF/LICENSE'
        exclude 'META-INF/license.txt'
        exclude 'META-INF/LGPL2.1'
        exclude 'META-INF/NOTICE.txt'
        exclude 'META-INF/NOTICE'
        exclude 'META-INF/notice.txt'
    }
}

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

Silahkan lihat pada komentar Sakiboy ini !

Jawaban yang ketinggalan jaman

Dari Gradle 0.9.1 berikut ini didukung:

android.packagingOptions {
    pickFirst 'META-INF/LICENSE.txt'
}

Informasi lebih lanjut dalam catatan rilis Gradle .

Masalah yang sama ketika saya mengekspor perpustakaan httclient-4.3.5 di Android Studio 0.8.6 Saya perlu menyertakan ini:

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

Pustaka zip membuat isi jar berikutnya:

commons-codec-1.6.jar
commons-logging-1.1.3.jar
fluent-hc-4.3.5.jar
httpclient-4.3.5.jar
httpclient-cache-4.3.5.jar
httpcore-4.3.2.jar
httpmime-4.3.5.jar

Bug ini masih ada di 0,8 + / 1,10

Dengan Jackson

compile 'com.fasterxml.jackson.dataformat:jackson-dataformat-csv:2.2.2'

Saya harus memasukkan serta saran di atas sebelum akan dikompilasi

exclude 'META-INF/services/com.fasterxml.jackson.core.JsonFactory'

Ini lebih dari satu kesalahan

Dibawah apply plugin: 'android-library'

Tambahkan ini ::

android {
    packagingOptions {
        exclude 'META-INF/ASL2.0'
        exclude 'META-INF/LICENSE'
        exclude 'META-INF/NOTICE'
    }
}

Dalam hal duplikat file itu mudah, lihat di JARdalam META-INFdirektori dan lihat apa yang menyebabkan kesalahan. Bisa jadi banyak. Dalam kasus saya, plugin Couchbase Lite. Saat Anda menambahkan lebih banyak plugin, Anda akan membutuhkan lebih banyak pengecualian

Masalah yang sama ketika saya menggunakan 'org.springframework.android:spring-android-rest-template:.0.0.M1' di Android Studio 1.0.1. Saya perlu memasukkan ini ke dalambuild.gradle

android{
...
    packagingOptions{
        exclude 'META-INF/notice.txt'
        exclude 'META-INF/license.txt'
    }
...
}

Ini bekerja untuk saya:

android {
   packagingOptions {
       exclude 'LICENSE.txt'
   }
}

Saya pikir Anda harus menyertakan hanya opsi ini di build.gradle :

packagingOptions {
        exclude 'META-INF/DEPENDENCIES'
        exclude 'META-INF/NOTICE'
        exclude 'META-INF/LICENSE'
    }

ps jawaban yang sama dari posting saya di: Kesalahan :: file duplikat selama pengemasan APK

Masalahnya adalah bahwa folder META-INF tidak akan disaring sehingga banyak entri NOTICEatau LICENSEmenyebabkan duplikat saat membangun dan dicoba untuk menyalinnya bersama.

Perbaikan Cepat Kotor:

Buka .jarfile di .gradle/caches/...folder Anda (dengan alat yang kompatibel dengan zip) dan hapus atau ganti nama file di META-INFfolder yang menyebabkan kesalahan (biasanya NOTICEatau LICENSE). (Saya tahu itu juga di OP, tetapi bagi saya itu tidak benar-benar jelas sampai saya membaca forum google)

EDIT:

Ini diperbaiki di 0.7.1. Cukup tambahkan file confilcting untuk dikecualikan.

android {
    packagingOptions {
        exclude 'META-INF/LICENSE'
    }
}

Sama di sini dengan

dependencies {
    compile 'org.apache.oltu.oauth2:org.apache.oltu.oauth2.client:1.0.0'
}

packagingOptions {
    exclude 'META-INF/DEPENDENCIES'
    exclude 'META-INF/LICENSE'
    exclude 'META-INF/NOTICE'
}

Saya kehilangan 2 hari untuk kesalahan aneh itu ... Mengapa ini masih terjadi di kelas 1.0.0? Itu sangat mengganggu bagi pemula ... Pokoknya, terima kasih untuk info yang saya pikir itu pada kode saya :)

Penting untuk mengetahui file apa yang menyebabkan kesalahan ini (dalam contoh Anda itu adalah META-INF / LICENSE.txt), dalam kasus saya ini ada di META-INF / LICENSE [tanpa ".txt"], lalu dalam file tersebut META-INF / ASL2.0 jadi saya menambahkan ke build.gradle baris saya ini:

android {
    packagingOptions {
        exclude 'META-INF/LICENSE'
        exclude 'META-INF/ASL2.0'
    }
}

Sangat penting (!) -> tambahkan nama file dengan gaya yang sama, yang Anda lihat dalam pesan kesalahan: teks peka huruf besar-kecil, dan ada perbedaan antara * .txt dan * (tanpa "txt") .

Jika Anda ingin melakukan bagian Anda sebagai pengembang, menggunakan pustaka sumber terbuka, Anda harus mencoba memasukkan semua lisensi sumber terbuka di dalam pustaka Anda apk. Untuk melakukan ini, Anda bisa menggunakan metode menggabungkan di packagingOptions.

Contoh:

packagingOptions {
        // This will get include every license and notice regardless of what dir it’s in.
        merge '**/LICENSE.txt'
        merge '**/NOTICE.txt'
        merge '**/notice.txt'
        merge '**/license.txt'
        merge '**/NOTICE'
        merge '**/LICENSE'
        merge '**/notice'
        merge '**/license'
        merge '**/LGPL2.1'
        // This will exclude any README files, regardless of the dir or the file type.
        exclude '**/README.*'
}

Jawaban ini lebih baik daripada menggunakan pickFirstkarena metode itu hanya mengambil lisensi pertama yang ditemukannya dan mengabaikan semua yang lain, agak menjadikannya tidak berguna dalam kasus ini.

Jadi singkatnya, gunakan mergemetode ini untuk memasukkan semua lisensi dari pustaka sumber terbuka kickass yang telah Anda gunakan.

Info lebih lanjut tentang Pilihan Gradle Pengemasan .

Saya perhatikan komentar komit ini di AOSP, solusinya adalah mengecualikan beberapa file menggunakan DSL. Mungkin ketika 0.7.1 dirilis.

commit e7669b24c1f23ba457fdee614ef7161b33feee69
Author: Xavier Ducrohet <--->
Date:   Thu Dec 19 10:21:04 2013 -0800

    Add DSL to exclude some files from packaging.

    This only applies to files coming from jar dependencies.
    The DSL is:

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

Dalam kasus saya, saya hanya perlu menambahkan file build.gradle proyek:

android {
  packagingOptions {
    exclude 'META-INF/notice.txt'
    exclude 'META-INF/license.txt'
  }

   ...
}

Di Android Studio 1.1.0 saya membutuhkan nama huruf kecil:

packagingOptions{
      exclude 'META-INF/license.txt'
      exclude 'META-INF/notice.txt'
}

File "LICENSE.txt" dan "NOTICE.txt" peka huruf besar-kecil. Jadi untuk perpustakaan android SPring saya harus menambahkan

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

Menghapus .txt setelah LICENSE menghapus kesalahan saya:

packagingOptions {
    exclude 'META-INF/LICENSE'
}

  packagingOptions {
    exclude 'META-INF/DEPENDENCIES.txt'
    exclude 'META-INF/DEPENDENCIES'
    exclude 'META-INF/dependencies.txt'
    exclude 'META-INF/LICENSE.txt'
    exclude 'META-INF/LICENSE'
    exclude 'META-INF/license.txt'
    exclude 'META-INF/LGPL2.1'
    exclude 'META-INF/NOTICE.txt'
    exclude 'META-INF/NOTICE'
    exclude 'META-INF/notice.txt'
}
