程序类型已经存在：com.google.common.util.concurrent.ListenableFuture [英] Program type already present: com.google.common.util.concurrent.ListenableFuture

问题描述

我刚刚将项目转换为androidx，现在出现 com.google.common.util.concurrent.ListenableFuture 的程序类型已存在错误。 / p>

我浏览了多个stackoverflow解决方案和一些Gradle文档，但仍然无法正常工作。

问题在于，Gradle在这些模块中引入了两个版本的ListenableFuture：

  Gradle：com.google。 quava：quava：23.5jre@jar 
摇篮：com.google.guava：listenablefuture：1.0@jar 
  

我想我想排除第二个，但不知道如何做。

您可以看到我在我的产品中尝试过的内容gradle文件，但到目前为止还没有喜悦。

  Apply插件：'com.android.application'

如果我正确地查看了依赖项，它似乎来自 androidx .core：core：1.1.0-alpha03 。

 +-com.google.guava：listenablefuture：1.0 @ jar 
  

建议。谢谢。

解决方案

找到了问题和答案。在项目视图中查看外部库，我发现了以下内容：

 等级：com.google.guava：guava：23.5- jre @ jar 
 | _ guava-23.5-jre.jar 
 | _com.google 
 | _common 
 | _util.concurrent 
 | _ListenableFuture 
 
 Gradle：com.google.guava：listenablefuture：1.0@jar 
 | _listenablefuture-1.0.jar 
 | _com.google.common.util.concurrent 
 | _ListenableFuture 
  

第二个条目中唯一的东西是重复的ListenableFuture。

通过在gradle构建文件中进行以下输入，此问题就消失了：

  configurations.all {
 resolutionStrategy .eachDependency {DependencyResolveDetails详细信息-> 
 def请求= details.requested 
 if（requested.group == com.android.support）{
 if（！requested.name.startsWith（ multidex））{
 details.useVersion 26. + 
} 
} 
} 
 
 all *。排除组： com.google.guava，模块： 'listenablefuture'< ===这解决了问题
} 
  

我不知道找出产生 com.google.guava：listenablefuture：1.0@jar 的原因，但解决了所产生的问题。

感谢所有审核过该问题的人。

I have just converted my project to androidx and am now getting the "Program type already present" error for com.google.common.util.concurrent.ListenableFuture.

I have looked through multiple stackoverflow solutions and some of the Gradle documentation and still can't get it to work.

The problem is that there are two versions of ListenableFuture brought in by Gradle in these modules:

Gradle: com.google.quava:quava:23.5jre@jar 
Gradle: com.google.guava:listenablefuture:1.0@jar

I would guess that I want to exclude the second one, but can not figure out how to do it.

You can see what I have tried in my gradle file, but no joy so far.

    apply plugin: 'com.android.application'

android {
    compileSdkVersion 28
    defaultConfig {
        applicationId "com.drme.weathertest"
        minSdkVersion 26
        targetSdkVersion 27
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }

//    added 1/2/19 to try and prevent java.lang.NoClassDefFoundError: Failed resolution of:
//    Landroid/view/View$OnUnhandledKeyEventListener;
    configurations.all {
        resolutionStrategy.eachDependency { DependencyResolveDetails details ->
            def requested = details.requested
            if (requested.group == "com.android.support") {
                if (!requested.name.startsWith("multidex")) {
                    details.useVersion "26.+"
                }
            }
        }
//        resolutionStrategy.force 'com.google.quava.listenablefuture:1.0',
//                'com.google.common.util.concurrent.listenablefuture'
    }

//    compile('com.google.guava:listenablefuture:1.0@jar') {
//        // causing "Program type already present" compile errors
//        //exclude("com.google.guava:listenablefuture:1.0")
//        exclude('com.google.guava:listenablefuture')
//        exclude('listenablefuture-1.0.jar')
//        //exclude("maven.com.google.quava.listenablefuture")
//    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }

    sourceSets {
        main {
            java.srcDirs = ['src/main/java', 'src/main/java/com.drme.weatherNoaa/Data', 'src/main/java/2']
        }
    }
    compileOptions {

    // causing "Program type already present" compile errors // did not fix problem
    implementation('com.google.guava:listenablefuture:1.0') {

    }

    testImplementation 'junit:junit:4.12'

    implementation 'androidx.appcompat:appcompat:1.1.0-alpha01'
    implementation 'androidx.media:media:1.1.0-alpha01'
    implementation 'androidx.room:room-runtime:2.1.0-alpha03'
    implementation 'androidx.room:room-testing:2.1.0-alpha03'
    implementation 'androidx.constraintlayout:constraintlayout:2.0.0-alpha3'
    implementation 'com.google.android.gms:play-services-location:16.0.0'
    implementation 'androidx.core:core:1.1.0-alpha03'
    implementation 'androidx.room:room-compiler:2.1.0-alpha03'
}

If I am looking at the dependencies correctly, it looks like it comes from androidx.core:core:1.1.0-alpha03.

+--- androidx.core:core:1.1.0-alpha03@aar
+--- androidx.concurrent:concurrent-futures:1.0.0-alpha02@jar
+--- com.google.guava:listenablefuture:1.0@jar   

Suggestions would be appreciated. Thanks.

解决方案

Found the problem and the answer. Looking at the External Libraries in the Project view I found the following:

Gradle: com.google.guava:guava:23.5-jre@jar 
 |_ guava-23.5-jre.jar 
    |_com.google
      |_common 
        |_util.concurrent
          |_ListenableFuture

Gradle: com.google.guava:listenablefuture:1.0@jar
 |_listenablefuture-1.0.jar
   |_com.google.common.util.concurrent
     |_ListenableFuture

The only thing in the second entry was the duplicate ListenableFuture.

By making the following entry in the gradle build file, this problem went away:

configurations.all {
        resolutionStrategy.eachDependency { DependencyResolveDetails details ->
            def requested = details.requested
            if (requested.group == "com.android.support") {
                if (!requested.name.startsWith("multidex")) {
                    details.useVersion "26.+"
                }
            }
        }

        all*.exclude group: 'com.google.guava', module: 'listenablefuture' <===This fixed the problem
    }

I could not figure out what was generating the com.google.guava:listenablefuture:1.0@jar, but the resulting problem was solved.

Thanks for all who reviewed the problem.
