Android測試Maven插件引發和錯誤：java.lang.NoClassDefFoundError：junitx.util.PrivateAccessor

Question

我已經創建了一個maven項目來自動執行android測試。它工作正常，直到我添加了junit-addons以測試私有字段。我添加以下依賴的POM文件：

<dependency> 
     <artifactId>junit-addons</artifactId> 
     <groupId>junit-addons</groupId> 
     <version>1.4</version> 
     <scope>provided</scope> 
</dependency> 

然後，它讓我對正在使用PrivateAccessor每個測試用例的錯誤。該錯誤是像波紋管：

java.lang.NoClassDefFoundError: junitx.util.PrivateAccessor 

我刪除<scope>provided</scope>並運行該項目，但它給了我下面的錯誤：

trouble processing "javax/xml/parsers/DocumentBuilder.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. 

任何幫助，將不勝感激。

我自己找到了解決方案。它給出了錯誤，因爲junit-addons依賴於另外三個庫。我只是從我的依賴中剔除這些庫。

我應該刪除<scope>privided</scope>並添加下面的JUnit插件dependecy：

<dependency> 
      <groupId>junit-addons</groupId> 
      <artifactId>junit-addons</artifactId> 
      <version>1.4</version> 
      <exclusions> 
       <exclusion> 
        <groupId>junit</groupId> 
        <artifactId>junit</artifactId> 

       </exclusion> 

       <exclusion> 
        <groupId>xerces</groupId> 
        <artifactId>xercesImpl</artifactId> 

       </exclusion> 

       <exclusion> 
        <groupId>xerces</groupId> 
        <artifactId>xmlParserAPIs</artifactId> 

       </exclusion> 
      </exclusions> 
     </dependency>
