在jetified-hamcrest-core-1.3.jar模块中找到重复的类org.hamcrest.BaseDescription [英] Duplicate class org.hamcrest.BaseDescription found in modules jetified-hamcrest-core-1.3.jar

问题描述

Android Studio 3.6

Android studio 3.6

app/build.gradle:

app/build.gradle:

 androidTestImplementation 'androidx.test.ext:junit:1.1.1'
    androidTestImplementation 'com.azimolabs.conditionwatcher:conditionwatcher:0.2'
    // Espresso framework
    androidTestImplementation "androidx.test.espresso:espresso-core:$espresso_version"
    androidTestImplementation "androidx.test.espresso:espresso-intents:$espresso_version"
    androidTestImplementation "androidx.test.espresso:espresso-contrib:$espresso_version"
    androidTestImplementation 'org.hamcrest:hamcrest-junit:2.0.0.0'

    // UI Automator framework
    androidTestImplementation 'androidx.test.uiautomator:uiautomator:2.2.0'
    androidTestImplementation 'com.squareup.okhttp3:mockwebserver:3.8.0'

    // for test fragments
    debugImplementation 'androidx.fragment:fragment-testing:1.2.0-rc02'

    testImplementation 'junit:junit:4.12'
    testImplementation 'com.nhaarman:mockito-kotlin-kt1.1:1.5.0'

在gradle.properties中:

in gradle.properties:

android.useAndroidX=true
android.enableJetifier=true

这是我的意式咖啡机测试:

Here my Espresso instrumentation test:

import okhttp3.mockwebserver.MockWebServer
import org.junit.After
import org.junit.Before
import org.junit.Rule
import org.junit.Test
import org.hamcrest.text.MatchesPattern
import org.junit.runner.RunWith

@RunWith(AndroidJUnit4::class)
class FeedbackActivityTransportTest {
 @Test
    fun buttonSend_click_checkRequest() {
        val request = mockServer.takeRequest();
        assertEquals("POST", request.method)
        assertThat(
            request.body.toString(),
            MatchesPattern.matchesPattern("(\"feedback.*\\\"type\\\":2\"))")
        )
    }

但是我得到了错误:

Duplicate class org.hamcrest.BaseDescription found in modules jetified-hamcrest-core-1.3.jar (org.hamcrest:hamcrest-core:1.3) and jetified-java-hamcrest-2.0.0.0.jar (org.hamcrest:java-hamcrest:2.0.0.0)

推荐答案

我认为当您添加依赖项时(例如您的情况 Hamcrest 以及另一个依赖项，库，Jar文件等...是也使用Hamcrest！但有另一个版本.

I think this problem happened when you add a dependency (as your situation Hamcrest and another dependency, library, Jar files, etc... is using Hamcrest too! but with another version.

如果您像下面这样在 app Gradle 中强制您的 Hamcrest 依赖关系，可能会解决您的问题:

If you force your Hamcrest dependency in app Gradle like below might solve your problem:

configurations.all {
    resolutionStrategy {
        force 'org.hamcrest:hamcrest-junit:2.0.0.0'
    }
}

在应用后，如果遇到相同的错误，请尝试排除，如下所示:

After apply if you get the same error try to exclude like this:

configurations { compile.exclude group: "junit", module: "junit" }
