android - iTextPdf-Android Studio添加库错误

Question

我想将itext lib添加到我的项目中。(http://itextpdf.com/itextg-android)

我将jar文件添加到libs文件夹中。之后，我写了一个build.gradle:编译files('libs/itextg-5.5.4.jar')。

但是同步之后，我得到了这个错误:

Error:(12, 0) Gradle DSL method not found: 'compile()' Possible causes:

The project 'Pdf' may be using a version of Gradle that does not contain the method. Gradle settings

The build file may be missing a Gradle plugin. Apply Gradle plugin

另外这里( http://www.codeproject.com/Articles/986574/Android-iText-Pdf-Example)是关于这个的解决方案，但是当我这样做时，我遇到了另一个错误

Error:Failed to resolve: org.apache.commons:commons-imaging:1.0-SNAPSHOT Open File

请检查是否添加了所有必需的软件包，然后，您的buil.gradle如下所示:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 22
    buildToolsVersion "22.0.1"

    defaultConfig {
        applicationId "com.proyecto.alberto.monedero"
        minSdkVersion 16
        targetSdkVersion 22
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:22.0.0'
    compile files('libs/itextg-5.5.4.jar')
    compile files('libs/itextg-5.5.4-sources.jar')
    compile files('libs/itextg-5.5.4-javadoc.jar')
    compile 'com.google.android.gms:play-services:7.0.0'
}
