如何解决重复级依赖问题

Question

我试过用罗比测试我的代码。问题是它有重复的引用。例如：

java.lang.RuntimeException: java.lang.RuntimeException: Duplicate class org.apache.maven.artifact.Artifact found in modules maven-ant-tasks-2.1.3.jar (org.apache.maven:maven-ant-tasks:2.1.3) and maven-artifact-2.2.1.jar (org.apache.maven:maven-artifact:2.2.1)

我已经使用gradel工件app:dependencies获得了下面的报告。在这里，重要的部分：

如何解决参考错误？在我看来，在不同的依赖关系中，知更鸟有相同的类吗？

我使用以下构建脚本: apply plugin：'com.android.application‘

apply plugin: 'idea'

idea {
    module {
        downloadJavadoc = true
        downloadSources = true
    }
}
android {
    compileSdkVersion 28
    buildToolsVersion '28.0.3'
    useLibrary 'org.apache.http.legacy'
    useLibrary 'android.test.runner'

    useLibrary 'android.test.base'
    useLibrary 'android.test.mock'

    defaultConfig {
        applicationId "com.example.sampleapp"
        minSdkVersion 16
        targetSdkVersion 28
        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }

    testOptions {
        unitTests {
            includeAndroidResources = true
        }
    }
}

dependencies {
    androidTestImplementation 'androidx.test:rules:1.2.0'
    androidTestImplementation 'androidx.test:core:1.2.1-alpha02'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'
    androidTestImplementation 'org.robolectric:robolectric:4.3'

    // Mail-Versand
    implementation 'com.sun.mail:android-mail:1.6.2'
    implementation 'com.sun.mail:android-activation:1.6.2'

    implementation 'androidx.appcompat:appcompat:1.0.2'//
    implementation 'com.github.woxthebox:draglistview:1.6.6'
}

怎么解决这个问题？

关于github的问题已开放：https://github.com/robolectric/robolectric/issues/5235

Answer 1

终于开始测试了。我已经排除了所有具有重复类的libs：

testImplementation ("org.robolectric:robolectric:4.3"){
    exclude group: 'org.apache.maven', module: 'maven-artifact'
    exclude group: 'org.apache.maven', module: 'maven-artifact-manager'
    exclude group: 'org.apache.maven', module: 'maven-model'
    exclude group: 'org.apache.maven', module: 'maven-plugin-registry'
    exclude group: 'org.apache.maven', module: 'maven-profile'
    exclude group: 'org.apache.maven', module: 'maven-project'
    exclude group: 'org.apache.maven', module: 'maven-settings'
    exclude group: 'org.apache.maven', module: 'maven-error-diagnostics'
    exclude group: "org.apache.maven.wagon"
}

并不是所有的可能性都经过测试，但是一个简单的测试已经奏效了。

Answer 2

这可能是以更一般的方式编写的：

testImplementation ("org.robolectric:robolectric:4.3") {
    exclude group "org.apache.maven.wagon"
    exclude group "org.apache.maven"
}

甚至：

testImplementation ("org.robolectric:robolectric:4.3") {
    exclude group: "org.apache.maven", name: "maven-ant-tasks"
}

因为它是maven-ant任务 of 鲁吉纳皮，它引入了org.apache.maven依赖项。

Answer 3

我遇到了同样的问题，帮助我的是，我在Gradle文件中定义了两次机器人电气依赖关系，一次用androidTestImplementation，另一次用testImplementation，所以当我删除第一部分时，问题解决了！
