无法将 Ksoap2 依赖项添加到 Android 项目

Question

我一直在尝试将 ksoap2 添加到我的 android 项目中。下面是我的 build.gradle 文件：

apply plugin: 'com.android.application'

repositories {
mavenCentral()

maven {
    url 'https://oss.sonatype.org/content/repositories/ksoap2-android-releases/'
}
}


android {
compileSdkVersion 23
buildToolsVersion "23.0.2"


defaultConfig {
    applicationId "com.rsa.mobile.android.transactionsigningsdk"
    minSdkVersion 14
    targetSdkVersion 23
    versionCode 1
    versionName "1.0"
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'),    'proguard-rules.pro'
    }

}
}

dependencies {
compile('com.thoughtworks.xstream:xstream:1.4.7') {
    exclude group: 'xmlpull'
}
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:23.1.0'
compile 'com.android.support:design:23.1.0'
compile ('com.google.code.ksoap2-android:ksoap2-android:3.0.0')
}

该项目编译正常，没有错误，但是当运行我的设备上的应用程序出现以下错误时：

我已经查找了几乎所有相关问题以查找此类错误，但没有任何效果。我试过：

1) 清理项目

2) 添加

android {
dexOptions {
preDexLibraries = false
}
}

到我的 gradle 文件

3) 添加

{
exclude group: 'xmlpull'
}

还有很多其他的东西，但没有任何帮助。我还用 ksoap2 创建了一个新的 android 项目并且成功了。下面是工作 build.gradle:

apply plugin: 'com.android.application'

repositories {
    mavenCentral()

    maven {
        url 'https://oss.sonatype.org/content/repositories/ksoap2-android-releases/'
    }
}

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.2"

    defaultConfig {
        applicationId "com.rsa.mobile.test_ksoap"
        minSdkVersion 14
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {

    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.1.0'
    compile 'com.android.support:design:23.1.0'
    compile 'com.google.code.ksoap2-android:ksoap2-android:3.0.0'
}

它的 xstream 和 ksoap2 一起使用时会导致问题，但我不知道如何解决这个问题。当彼此单独使用时，我的代码有效

有人可以帮忙吗。到目前为止，我已经做了我能做的一切，一点运气都没有。

Answer 1

我终于找到了解决办法。我们应该添加添加 ksoap2 依赖项时排除模块：'xmlpull' 而不是排除组：'xmlpull'。
