错误：任务“：app：transformClassesWithJarMergingForDebug”重复条目执行失败

Question

我通过手动添加不同文件（如menifest、java、res）的代码将我的eclipse项目转换为android studio。当我运行项目时它显示错误：

Error:Execution failed for task ':app:transformClassesWithJarMergingForDebug'. com.android.build.api.transform.TransformException: java.util.zip.ZipException: duplicate entry: android/support/annotation/IntegerRes.class  

这是我的 gradle 文件：

apply plugin: 'com.android.application'

android {
compileSdkVersion 25
buildToolsVersion "25.0.3"
useLibrary 'org.apache.http.legacy'

defaultConfig {

    applicationId "com.example.tms032.demo_pos_rs"
    minSdkVersion 19
    targetSdkVersion 25
    versionCode 1
    versionName "1.0"
    multiDexEnabled true
    testInstrumentationRunner 
    "android.support.test.runner.AndroidJUnitRunner"
}


buildTypes {
    release {

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

dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', 
{
    exclude group: 'com.android.support', module: 'support-annotations'
})
compile 'com.android.support:appcompat-v7:25.3.1'
compile 'com.android.support:design:25.3.1'
compile 'com.android.support:support-v4:25.3.1'
compile 'com.android.support:multidex:1.0.1'
compile project(':CustomCalendarView')
compile files('libs/commons-discovery-0.2.jar')
compile files('libs/commons-lang-2.5.jar')
compile files('libs/gson-2.2.2.jar')
compile files('libs/javax.wsdl_1.6.2.v201005080631.jar')
compile files('libs/log4j-1.2.16.jar')
compile files('libs/picasso-2.0.0.jar')
compile files('libs/posindev.jar')
compile files('libs/printingSDK-7.5.0-javadoc.jar')
compile files('libs/sqljet.1.0.2.b885.jar')
compile files('libs/upg_bridge.jar')
testCompile 'junit:junit:4.12'

}

如何读取此错误？我尝试了很多解决方案。但它们都不起作用。

Answer 1

compile fileTree(include: ['*.jar'], dir: 'libs')

compile files('libs/commons-discovery-0.2.jar')

你也在编译两次 jar 文件

当有不同版本的相同库时会有问题，

您可以将它们从 jar 依赖项中排除，如下所示，但这几乎不起作用。

sourceSets {
    main {
        java {
            include 'com/ourcompany/somepackage/activityadapter/**'
            include 'com/ourcompany/someotherpackage/**'
            exclude 'com/ourcompany/someotherpackage/polling/**'
        }
    }

最好的选择是找到新版本的 repo 而不是 jar。
