java - 将 iText 5.5.6 添加到带有 gradle 异常的 Android 项目

Question

我正在尝试使用 Android Studio (gradle) 将 iTextPDF 库添加到 Android 项目。我使用 compile 'com.itextpdf:itextpdf:5.5.6' 指令添加库，但出现错误:

Error:Execution failed for task ':app:dexDebug'. com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command '/opt/jdk1.7.0_79/bin/java'' finished with non-zero exit value 2

我的 build.gradle 是:

apply plugin: 'com.android.application'

android {
 compileSdkVersion 22
 buildToolsVersion "21.1.2"

defaultConfig {
    applicationId "josealopez.com.software"
    minSdkVersion 14
    targetSdkVersion 22
    versionCode 104
    versionName "1.0.4"
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}
packagingOptions {
    exclude 'META-INF/ASL2.0'
    exclude 'META-INF/LICENSE'
    exclude 'META-INF/NOTICE'
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:22.0.0'
compile 'com.couchbase.lite:couchbase-lite-android:1.0.4'
compile 'com.google.code.gson:gson:2.3.1'
compile 'com.google.android.gms:play-services:7.0.0'
compile 'com.itextpdf:itextpdf:5.5.6'
}

我把这两个依赖放在了gradle中:

compile 'com.itextpdf:itext-pdfa:5.5.10'
compile 'com.itextpdf:itextg:5.5.9'
