使用 Android Gradle 插件 0.7.0 和以下功能：build.gradle

        mavenCentral()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:0.7.0'

你应该清楚你的措辞：你没有使用 gradle 0.7.0 - 它是 android gradle 插件。它在 1.9.0 版中使用 gradle（带包装器）。错误的措辞会导致混淆 - 除了给定的上下文。

从 Android Studio 版本 0.8.14 开始

您应该添加：

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

添加到您的文件中。build.gradle

历史：

根据此错误中的评论 14： https://issuetracker.google.com/issues/36982149#comment14 这是 Android Gradle 插件 v0.7.0 中的一个错误，很快就会在 0.7.1 中修复。

以下是该错误中关于 0.7.1 添加的注释：

0.7.1 已解决此问题。

排除文件的 DSL 为：

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

您可以根据需要添加任意数量的 exclude 语句。该值是存档路径。尚不支持通配符或 glob。

文件名“LICENSE.txt”和“NOTICE.txt”区分大小写。请尝试使用“许可证.txt”和“通知.txt”。

@um.anusorn Sean 为您提供了一个很好的 gradle 文件示例，该文件在打包过程中从库中排除了这些文件。这就是我所拥有的： packagingOptions { exclude 'META-INF/LICENSE' exclude 'META-INF/NOTICE' exclude 'META-INF/DEPENDENCIES' exclude 'META-INF/license.txt' exclude 'META-INF/dependenices.txt' exclude 'META-INF/notice.txt' }

问题是 META-INF 文件夹不会被过滤，因此在构建时会有多个条目或导致重复，并尝试将它们复制在一起。NOTICELICENSE

肮脏的快速修复：

打开文件夹中的文件（使用 zip 兼容工具），然后删除或重命名文件夹中导致错误的文件（通常或 ）。（我知道这也在 OP 中，但对我来说，直到我阅读谷歌论坛才真正清楚）.jar.gradle/caches/...META-INFNOTICELICENSE

编辑：

此问题已在 0.7.1 中修复。只需添加要排除的 confilcting 文件即可。

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

是的，这就是为什么它用粗体字母写着“Dirty Quick Fix”。此外，正确的解决方案也只是一个段落。你确实意识到这是在没有干净解决方案的时候编写的，但人们仍然需要编译他们的应用程序。

我在 AOSP 中注意到了这个提交注释，解决方案是使用 DSL 排除一些文件。大概在 0.7.1 发布时。

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'
      }
    }

就我而言，我必须包括几个额外的排除项。它似乎不喜欢正则表达式，这将使它成为一个不错的单行。

android {

重要的是要知道在哪个文件中出现此错误（在您的示例中是 META-INF/LICENSE.txt），就我而言，它是在 META-INF/LICENSE [没有“.txt”]中，然后在文件 META-INF/ASL2.0 中，所以我在我的 build.gradle 中添加了以下行：

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

非常重要 （！） -> 以相同的样式添加文件的名称，您在错误消息中看到它：文本区分大小写，并且 *.txt 和 *（没有“txt”）之间存在差异。

就我而言，我只需要添加到项目的build.gradle文件中：

}

当我在Android Studio 1.0.1中使用“ org.springframework.android：spring-android-rest-template：2.0.0.M1”时，也遇到了同样的问题。我需要把它包含在build.gradle

android{

    }

同样在这里

}

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

我因为这个奇怪的错误损失了 2 天......为什么这在gradle 1.0.0中仍然发生？这对新手来说非常令人不安...... 无论如何，感谢您的信息，我认为它在我的代码:)

在Android Studio 1.1.0中，我需要小写名称：

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

不止一个错误

下apply plugin: 'android-library'

添加这个 ：：

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

如果文件重复，这很容易，请查看目录下方并查看导致错误的原因。它可以是多个。就我而言，Couchbase Lite插件。 当您添加更多插件时，您将需要更多的例外JARMETA-INF

愚蠢的问题：JAR文件在哪里？

在 Android Studio 中，运行带有该标志的 Gradle 可以让我看到添加到 apk 的类的日志，然后我可以向上搜索以查找从不同 JAR 添加的相同类的日志条目。这也向我展示了两个JAR文件的文件路径。我找不到选择一个 .class 文件而不是另一个文件的好方法，所以我修改了其中一个 JAR 文件并删除了重复的 .class--info

这对我有用：

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

我认为您只需要在build.gradle中包含以下选项：

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

p.s 与我的帖子中的答案相同： 错误 ：： APK 打包期间重复文件

文件“LICENSE.txt”和“NOTICE.txt”区分大小写。因此，对于 SPring android 库，我必须添加

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

在许可证删除我的错误后删除.txt：

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'
}

如果你想尽自己的一份力量，利用开源库，你应该尝试将所有这些开源许可证包含在你的 .为此，您可以在 .apkpackagingOptions

例：

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.*'
}

这个答案比使用要好，因为该方法只选择它找到的第一个许可证，而忽略所有其他许可证，在这种情况下有点使它变得无用。pickFirst

因此，简而言之，使用该方法包含您一直在使用的那些 kickass 开源库中的所有许可证。merge
