改造2.0 XML SimpleXML的轉換問題，而在gradle這個文件中有retrolambda

Question

這裏是我的gradle這個文件

apply plugin: 'com.android.application' 
apply plugin: 'me.tatarka.retrolambda' 
android { 
    compileSdkVersion 23 
    buildToolsVersion "23.0.2" 

    defaultConfig { 
     applicationId "com.demo.sample" 
     minSdkVersion 15 
     targetSdkVersion 23 
     versionCode 1 
     versionName "1.0" 
    } 
    buildTypes { 
     release { 
      minifyEnabled false 
      proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' 
     } 
    } 

    compileOptions { 
     sourceCompatibility JavaVersion.VERSION_1_8 
     targetCompatibility JavaVersion.VERSION_1_8 
    } 
} 

dependencies { 
    compile fileTree(dir: 'libs', include: ['*.jar']) 
    testCompile 'junit:junit:4.12' 
    compile 'com.android.support:appcompat-v7:23.2.0' 
    compile 'com.android.support:design:23.2.0' 

    //Retrofit 
    compile 'com.squareup.retrofit2:retrofit:2.0.0-beta4' 
    //Retrofit support libraries 
    compile 'com.squareup.retrofit2:converter-gson:2.0.0-beta4' 
    //compile 'com.squareup.retrofit2:converter-simplexml:2.0.0-beta4' 
    compile 'com.squareup.retrofit2:adapter-rxjava:2.0.0-beta4' 
    compile 'com.squareup.okhttp3:logging-interceptor:3.0.1' 
    //RxAndroid 
    compile 'io.reactivex:rxandroid:1.1.0' 
    //Explicit support for latest RxJava 
    compile 'io.reactivex:rxjava:1.1.0' 
    //Square dagger 
    provided 'com.squareup.dagger:dagger-compiler:1.2.2' 
    compile 'com.squareup.dagger:dagger:1.2.2' 
    //Butterknife 
    compile 'com.jakewharton:butterknife:6.1.0' 
    //Picasso 
    compile 'com.squareup.picasso:picasso:2.3.3' 
    //Testing dependency 
    testCompile 'junit:junit:4.12' 
    testCompile 'org.assertj:assertj-core:2.1.0' 
    testCompile 'org.mockito:mockito-core:2.0.23-beta' 
} 

如果我取消註釋行compile 'com.squareup.retrofit2:converter-simplexml:2.0.0-beta4'機器人工作室拋出在編譯時

:app:transformClassesWithDexForDebug 
trouble processing "javax/xml/XMLConstants.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.

我討厭的錯誤我不明白這個錯誤究竟意味着什麼。另外，有沒有辦法解決這個問題。

看起來像簡單的XML有已經包含在Android中的傳遞依賴。請參閱https://github.com/square/retrofit/issues/1536。 我們需要排除三個依賴關係：stax：stax-api，stax：stax和xpp3：xpp3。 我設法通過在gradle中使用此編譯語句來實現此目的

compile ('com.squareup.retrofit2:converter-simplexml:2.0.0-beta4'){ 
    exclude module: 'stax-api' 
    exclude module: 'stax' 
    exclude module: 'xpp3' 
}
