问题一：

描述：

Execution failed for task ':alpha1s:transformClassesWithDexForDebug'.
> com.android.build.api.transform.TransformException: com.android.ide.common.process.ProcessException: java.util.concurrent.ExecutionException: com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException:Process 'command 'C:\Program Files\Java\jdk1.8.0_73\bin\java.exe'' finished with non-zero exit value 2

解决：在主工程的build.gradle中

android {
compileSdkVersion 20
buildToolsVersion "23.0.2"

    defaultConfig {
        applicationId "com.ubt.alpha1s"
        minSdkVersion 14
        targetSdkVersion 22
        compileOptions {
            sourceCompatibility JavaVersion.VERSION_1_7
            targetCompatibility JavaVersion.VERSION_1_7

        }
        multiDexEnabled true
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
        }
    }
}

问题二：

描述：

Execution failed for task ':app:transformResourcesWithMergeJavaResForDebug'.
> com.android.build.api.transform.TransformException: com.android.builder.packaging.DuplicateFileException:Duplicate files copied in APK META-INF/LE-832C0.SF
File1: E:\Users\Yu Yong\AndroidStudioProjects\MyApplication\app\libs\neurotec-devices-fscanners-suprema-biomini-android.jar
File2: E:\Users\Yu Yong\AndroidStudioProjects\MyApplication\app\libs\neurotec-biometrics-android.jar

...

这个问题之所以出现是因为项目引用的众多jar包里面有重复的文件，例如上面例子中的META-INF/LE-832C0.SF

解决：在出现问题的Model --> gradle文件 --> android语句块内加上

packagingOptions {    exclude 'META-INF/LE-832C0.SF'}
