Question

我在尝试使用Maven和Eclipse创建项目时遇到了很多问题。它随机向我显示以下消息：

[2014-03-20 16:36:40 - App] Dx 
trouble processing "javax/xml/namespace/QName.class":

Ill-advised or mistaken usage of a core class (java.* or javax.*)
when not building a core library.

This is often due to inadvertently including a core library file
in your application's project, when using an IDE (such as
Eclipse). If you are sure you're not intentionally defining a
core class, then this is the most likely explanation of what's
going on.

However, you might actually be trying to define a class in a core
namespace, the source of which you may have taken, for example,
from a non-Android virtual machine project. This will most
assuredly not work. At a minimum, it jeopardizes the
compatibility of your app with future versions of the platform.
It is also often of questionable legality.

If you really intend to build a core library -- which is only
appropriate as part of creating a full virtual machine
distribution, as opposed to compiling an application -- then use
the "--core-library" option to suppress this error message.

If you go ahead and use "--core-library" but are in fact
building an application, then be forewarned that your application
will still fail to build or run, at some point. Please be
prepared for angry customers who find, for example, that your
application ceases to function once they upgrade their operating
system. You will be to blame for this problem.

If you are legitimately using some code that happens to be in a
core package, then the easiest safe alternative you have is to
repackage that code. That is, move the classes in question into
your own package namespace. This means that they will never be in
conflict with core system classes. JarJar is a tool that may help
you in this endeavor. If you find that you cannot do this, then
that is an indication that the path you are on will ultimately
lead to pain, suffering, grief, and lamentation.

[2014-03-20 16:36:40 - App] Dx 1 error; aborting
[2014-03-20 16:36:40 - App] Conversion to Dalvik format failed with error 1

当我随机说出来时，它实际上是随机的，几分钟前我运行该项目就好了，现在，它已经出现了。

我不知道发生了什么，因为我没有使用QName.class。

你知道发生了什么吗？

非常感谢

如果你正在使用 Maven安卓插件或 m2e-android ，你需要注意你的依赖关系：它看起来好像你有一个传递依赖包括javax.xml.* pacakage，如果您阅读错误消息，则对Dalvik编译是非法的。

解决方案：找到传递依赖关系和exclude it in your POM。

抱歉我迟到了：

当我开发项目的这一部分时，我还创建了一些库，但更像是 DataAccess 库或模型库，而不是创建< em> Android Project 我创建了一个简单的 Java库项目 ，因为我只使用了一些Android API，例如Context for DataAccess 模型的另一个，以及我的 pom.xml ，我没有排除 Android Jars 所以这造成了冲突。

以防有人做同样的事情......

谢谢!!
