title: Android Studio Error:Execution failed for task ':app:transformClassesWithDexForDebug'
body: <p>I got this error when I run my project. There's no error with the code, but I think the error maybe caused by the dependencies in gradle. Anyone can help? </p>
  
  <p>here's the error message:</p>
  
  <p>Error:Execution failed for task ':app:transformClassesWithDexForDebug'.</p>
  
  <blockquote>
    <p>com.android.ide.common.process.ProcessException:       org.gradle.process.internal.ExecException: Process 'command 'C:\Program Files\Java\jdk1.7.0_79\bin\java.exe'' finished with non-zero exit value 1</p>
  </blockquote>
  
  <p>and here is my build.gradle:</p>
  
  <pre><code>android {
      compileSdkVersion 23
      buildToolsVersion "24.0.0"
  
      defaultConfig {
          applicationId "link.dr.daniel.tickme"
          minSdkVersion 15
          targetSdkVersion 23
          versionCode 1
          versionName "1.0"
      }
      buildTypes {
          release {
             minifyEnabled false
              proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
          }
      }
  }
  
  dependencies {
      compile fileTree(dir: 'libs', include: ['*.jar'])
      testCompile 'junit:junit:4.12'
      compile 'com.android.support:appcompat-v7:23.4.0'
  }
  </code></pre>
  
  <p>Anyone know? thank you very much.</p>
