Android Studio：添加样板库后生成错误

Question

我正在尝试使用[boilerpipe] [1]来解析文本。 我将boilerpipe-1.2.0.jar ， nekohtml-1.9.13.jar和xerces-2.9.1.jar到lib文件夹，并将它们添加为库。 但是，当我尝试运行该项目时，我遇到了一个巨大的错误。 这是它的末端部分

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:transformClassesWithDexForDebug'.
> com.android.build.api.transform.TransformException: java.lang.RuntimeException: java.lang.RuntimeException: com.android.ide.common.process.ProcessException: java.util.concurrent.ExecutionException: com.android.ide.common.process.ProcessException: Return code 1 for dex process

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

这是我的应用程序build.gradle

apply plugin: 'com.android.application'

android {
    compileSdkVersion 25
    buildToolsVersion "25.0.0"
    defaultConfig {
        applicationId "com.example.pushpankar.reader"
        minSdkVersion 16
        targetSdkVersion 25
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner  "android.support.test.runner.AndroidJUnitRunner"
        multiDexEnabled true
    }
    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-v7:25.0.0'
    compile 'com.android.support:support-v4:25.0.0'
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:multidex:1.0.1'
    compile files('libs/boilerpipe-1.2.0/lib/xerces-2.9.1.jar')
    compile files('libs/boilerpipe-1.2.0/lib/nekohtml-1.9.13.jar')
    compile files('libs/boilerpipe-1.2.0/boilerpipe-1.2.0.jar')
}

这是带有--debug选项的输出

Answer 1

您正在使用什么JDK版本？

您必须使用相同或更高的Java版本，而不是用于编译外部jar（锅炉管道）的Java版本。

更新：

从您发布的错误日志中，看起来错误如下：

java.lang.IllegalArgumentException: bad utf-8 byte

并且此错误已填充到锅炉项目的github问题跟踪中： https : //github.com/matanster/boilerpipe/issues/74
