Eu tentei olhar para outros semelhantes e nenhuma solução funcionou. Já executei aplicativos sem problemas, mas meu novo aplicativo de repente começou a me dar problemas. Sempre falha quando tento executá-lo, dizendo:

Error:Execution failed for task ':app:preDexDebug'.
com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command 'C:\Program Files (x86)\Java\jdk1.7.0_67\bin\java.exe'' finished with non-zero exit value 1

Aqui está o que o console exibiu:

Executing tasks: [:app:assembleDebug]

Este aplicativo é muito simples e não mudei muito do layout das ações. Ele foi projetado apenas para pirulito e usa apenas recursos de estoque. Aqui está o build.gradle:

apply plugin: 'com.android.application'
android {
compileSdkVersion 22
buildToolsVersion "22.0.0"

defaultConfig {
    applicationId "com.package.app"
    minSdkVersion 21
    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:support-v4:22.0.0'
}
