我正在尝试生成一个已签名的.APK但是我正在通过一个问题。我已经看到有关此错误的多个类似问题。我认为这是此错误的具体情况：
Error:Execution failed for task ':app:transformClassesWithJarMergingForProdRelease'.

这是我的build.gradle：

可能会干扰此问题的另一个细节，我的IDE显示此消息：
所有com.android.support库必须使用完全相同的版本规范（混合版本可能导致运行时崩溃）。找到版本25.3.1,25.0.0。示例包括com.android.support:animated-vector-drawable:25.3.1和com.android.support:cardview-v7:25.0.0
我相信其中一些库在GMS版本方面相互冲突，但不幸的是我无法弄清楚哪些库以及如何解决这个问题。
提前谢谢
答案 0 :(得分：1)
问题是您有几个使用不同版本的支持库的依赖项，这些依赖项与您为项目明确声明的版本不同。您需要将所有这些标准化为单个版本。理想情况下，您希望使用最新版本的支持库。
第一步是确保使用所有依赖项的最新版本。如果幸运的话，这可能会立即解决问题。
如果仍然出现类似错误，则需要覆盖支持库版本。您可以通过两种方式执行此操作：
从使用支持库的每个依赖项中手动排除传递依赖项。你应该有选择地这样做，而不是整个销售。例如
compile 'com.jakewharton:butterknife:8.5.1', {
exclude group: 'com.android.support'
}
按照this answer中的说明覆盖支持图书馆版本。
如果您需要进一步的帮助，则应该显示错误消息，其中包含＆＃34;所有com.android.support库必须使用完全相同的版本规范＆＃34;。这将为您提供比＆＃34; java.util.zip.ZipException更好的结果：重复条目：＆＃34;。
