我正在尝试在Android上创建自己的应用程序但是当我尝试运行应用程序时出现以下错误
Error:Execution failed for task ':app:transformResourcesWithMergeJavaResForDebug'.

这个错误让我发疯，我做了很多搜索，但没有任何对我有用，大多数情况下这些家伙建议使用packagingOptions并排除META-INF我试过这个例如：
packagingOptions {
exclude 'META-INF/services'
}
更新
我添加了TML建议，现在我收到以下错误

Error:trouble processing "javax/xml/parsers/DocumentBuilder.class":
Error:Ill-advised or mistaken usage of a core class (java.* or javax.*)
Error:when not building a core library.
Error:This is often due to inadvertently including a core library file
Error:in your application's project, when using an IDE (such as
Error:Eclipse). If you are sure you're not intentionally defining a
Error:core class, then this is the most likely explanation of what's
Error:going on.
Error:However, you might actually be trying to define a class in a core
Error:namespace, the source of which you may have taken, for example,
Error:from a non-Android virtual machine project. This will most
Error:assuredly not work. At a minimum, it jeopardizes the
Error:compatibility of your app with future versions of the platform.
Error:It is also often of questionable legality.
Error:If you really intend to build a core library -- which is only
Error:appropriate as part of creating a full virtual machine
Error:distribution, as opposed to compiling an application -- then use
Error:the "--core-library" option to suppress this error message.
Error:If you go ahead and use "--core-library" but are in fact
Error:building an application, then be forewarned that your application
Error:will still fail to build or run, at some point. Please be
Error:prepared for angry customers who find, for example, that your
Error:application ceases to function once they upgrade their operating
Error:system. You will be to blame for this problem.
Error:If you are legitimately using some code that happens to be in a
Error:core package, then the easiest safe alternative you have is to
Error:repackage that code. That is, move the classes in question into
Error:your own package namespace. This means that they will never be in
Error:conflict with core system classes. JarJar is a tool that may help
Error:you in this endeavor. If you find that you cannot do this, then
Error:that is an indication that the path you are on will ultimately
Error:lead to pain, suffering, grief, and lamentation.

This is caused by library dependencies that have been compiled using Java 8 or above.
If you are using the 'java' gradle plugin in a library submodule add
targetCompatibility = '1.7'
sourceCompatibility = '1.7'
to that submodule's build.gradle file.

我刚刚遇到了几乎完全相同的问题。
添加此代码，就像TML说的那样，为我解决了这个问题：
android {
packagingOptions {
exclude 'META-INF/services/com.fasterxml.jackson.databind.Module'
}
}
答案 1 :(得分：1)
我刚刚帮助过有类似问题的人：Android Gradle Duplicate files copied in APK META-INF
每当看到Exception: Duplicate files copied in APK BLAH/blaha.blahb.blahc
将另一个exclude 'BLAH/blaha.blahb.blahc'添加到您的packagingOptions
所以在你的情况下：exclude 'META-INF/services/com.fasterxml.jackson.databind.Module'
这种异常可能会多次发生，直到你全部抓住它们为止！

在buildTypes：
下面的build.gradle文件中使用以下行packagingOptions {
exclude 'META-INF/NOTICE.txt' // will not include NOTICE file
exclude 'META-INF/LICENSE.txt' // will not include LICENSE file
}
并在同一文件中添加defaultConfig
multiDexEnabled true
