我有绝对空的Android项目生成

mvn archetype:generate -DarchetypeArtifactId=android-quickstart .......

它构建良好,部署合理,运行良好.问题是,当我添加

[INFO]

[INFO] trouble processing "javax/xml/namespace/QName.class":

[INFO]

[INFO] Ill-advised or mistaken usage of a core class (java.* or javax.*)

[INFO] when not building a core library.

[INFO]

[INFO] This is often due to inadvertently including a core library file

[INFO] in your application's project, when using an IDE (such as

[INFO] Eclipse). If you are sure you're not intentionally defining a

[INFO] core class, then this is the most likely explanation of what's

[INFO] going on.

[INFO]

[INFO] However, you might actually be trying to define a class in a core

[INFO] namespace, the source of which you may have taken, for example,

[INFO] from a non-Android virtual machine project. This will most

[INFO] assuredly not work. At a minimum, it jeopardizes the

[INFO] compatibility of your app with future versions of the platform.

[INFO] It is also often of questionable legality.

[INFO]

[INFO] If you really intend to build a core library -- which is only

[INFO] appropriate as part of creating a full virtual machine

[INFO] distribution, as opposed to compiling an application -- then use

[INFO] the "--core-library" option to suppress this error message.

[INFO]

[INFO] If you go ahead and use "--core-library" but are in fact

[INFO] building an application, then be forewarned that your application

[INFO] will still fail to build or run, at some point. Please be

[INFO] prepared for angry customers who find, for example, that your

[INFO] application ceases to function once they upgrade their operating

[INFO] system. You will be to blame for this problem.

[INFO]

[INFO] If you are legitimately using some code that happens to be in a

[INFO] core package, then the easiest safe alternative you have is to

[INFO] repackage that code. That is, move the classes in question into

[INFO] your own package namespace. This means that they will never be in

[INFO] conflict with core system classes. JarJar is a tool that may help

[INFO] you in this endeavor. If you find that you cannot do this, then

[INFO] that is an indication that the path you are on will ultimately

[INFO] lead to pain, suffering, grief, and lamentation.

之前尝试过Maven 2和Maven-android-plugin 2. *-结果是相同的.仅对simple-xml依赖项失败.在禁用simple-xml的情况下启用codegist-crest效果很好.仅当我使用simple-xml时才会发生这种情况.

我还尝试了在没有maven(Eclipse)的情况下进行同样的操作-在这种情况下,即使我的构建路径上具有simple-xml,一切都可以正常工作.

有任何想法吗？

解决方法:

这里的问题是simple-xml或更可能是其依赖项之一已经在保留的java.*或javax.*名称空间中定义了一个或多个类.在Android平台上不允许这样做.虽然,我不确定为什么这会在Eclipse中起作用.该库是否可能在构建路径上,但未包含在最终编译的APK中？

由于Android平台提供了许多与XML相关的软件包,因此您可能不需要simple-xml：
