错误：Gradle：任务'：app：dexDebug'的执行失败。 ＆GT; com.android.ide.common.process.ProcessException：

Question

我有android studio的问题，当我添加guava-18.jar lib并运行我的Main时出现错误：

Error:Gradle: Execution failed for task ':app:dexDebug'.>
com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command 'C:\Program Files\Java\jdk1.8.0_45\bin\java.exe'' finished with non-zero exit value 2

我尝试在build.gradle

中添加它

defaultConfig {
 multiDexEnabled true
}

但请勿解决。

请帮帮我!!!

my build gradle：

apply plugin: 'com.android.application'
android {
 compileSdkVersion 23
 buildToolsVersion "23.0.1"

defaultConfig {
    applicationId "it.unical.mat.myapp"
    minSdkVersion 15
    targetSdkVersion 23
    versionCode 1
    versionName "1.0"
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'),    'proguard-rules.pro'
    }
 }
}
dependencies {
 compile fileTree(include: ['*.jar'], dir: 'libs')
 compile 'com.android.support:appcompat-v7:23.0.1'
 compile 'com.android.support:support-v4:23.0.1'
 compile 'com.google.android.gms:play-services:8.1.0'
 compile files('libs/activation.jar')
 compile files('libs/gdata-analytics-2.1.jar')
 compile files('libs/gdata-core-1.0.jar')
 compile files('libs/gdata-spreadsheet-3.0.jar')
 compile files('libs/jsr305.jar')
 compile files('libs/mail.jar')
 compile files('libs/guava-18.0.jar')
}

在Gradle文件中需要添加“com.android.support:multidex:1.0.0”此Packeage

在Activity中需要更新

 MultiDex.install(this);
