I have tried to execute the simple “Get Started” tutorial, without edit any file, but simply using this command $ npm install -g cordova ionic $ ionic start test tabs $ ionic platform add android And all these 3 command work file. After i have run this $ ionic build android And the command fails with errors :compileDebugJavaWithJavacNote: /Users/andreabersi/app/test/platforms/android/src/org/apache/cordova/splashscreen/SplashScreen.java uses or overrides a deprecated API. Note: Recompile with -Xlint:deprecation for details. :compileDebugNdk UP-TO-DATE :compileDebugSources :transformClassesWithDexForDebugException in thread “main” java.lang.UnsupportedClassVersionError: com/android/dx/command/Main : Unsupported major.minor version 52.0 at java.lang.ClassLoader.defineClass1(Native Method) at java.lang.ClassLoader.defineClass(ClassLoader.java:800) at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:142) at java.net.URLClassLoader.defineClass(URLClassLoader.java:449) at java.net.URLClassLoader.access$100(URLClassLoader.java:71) at java.net.URLClassLoader$1.run(URLClassLoader.java:361) at java.net.URLClassLoader$1.run(URLClassLoader.java:355) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:354) at java.lang.ClassLoader.loadClass(ClassLoader.java:425) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:308) at java.lang.ClassLoader.loadClass(ClassLoader.java:358) at sun.launcher.LauncherHelper.checkAndLoadMain(LauncherHelper.java:482) FAILED FAILURE: Build failed with an exception. - What went wrong: Execution failed for task ‘:transformClassesWithDexForDebug’. > com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process ‘command ‘/Library/Java/JavaVirtualMachines/jdk1.7.0\_79.jdk/Contents/Home/bin/java’’ finished with non-zero exit value 1 - Try: Run with --stacktrace option to get the stack trace.

Same problem here. Is there a preferred version of JDK to use with ionic? already tried 7.0\_79 and \_80 (both x86 and x64), they all failed. Just to be clear, I altered JAVA\_HOME in every trial. The error occurs with the plain examples from ionic (blank, sidemenu and tabs): “Execution failed for task ‘:transformClassesWithDexForDebug’.” I tried adding " multiDexEnabled true" to my build.gradle, turns out the error is only delayed to arise with: “transformClassesWithMultidexListForDebug”. ---

It is probably the Java version. Turns out ionic getting started page directs you to the Android platform installation process, which referes to an old version of java (java 7). JDK 8 can be downloaded from here: [http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html](http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html) I will test it when I get home, but that is most likely the reason. ---
