title: Execution failed for task :app:compileDebugJavaWithJavac
body: <p>I picked up someone else's project and when I asked AS to run the project on my AVD, it pops me an error:</p>
  <blockquote>
  <p>Error:Execution failed for task ':app:compileDebugJavaWithJavac'.</p>
  <p>Compilation failed; see the compiler error output for details.</p>
  </blockquote>
  <p>Here is my <code>build.gradle</code></p>
  <pre><code>apply plugin: 'com.android.application'
  
  android {
      compileSdkVersion 23
      buildToolsVersion &quot;23.0.2&quot;
      defaultConfig {
          applicationId 'ca.gggolf.aminutegolf'
          minSdkVersion 19
          targetSdkVersion 23
          versionCode 1
          versionName &quot;1.0&quot;
      }
  
      buildTypes {
          release {
              minifyEnabled false
              proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
          }
      }
      productFlavors {
      }
  }
  
  dependencies {
      compile fileTree(include: ['*.jar'], dir: 'libs')
      testCompile 'junit:junit:4.12'
      compile 'com.android.support:appcompat-v7:23.1.1'
  }
  </code></pre>
  <p>I don't know what to do.. Everything else works fine and the app was working a couple of years ago when it was first made.</p>
