Mac上的Android Studio：无法找到系统编译器

Question

Im getting this on one of my macs when I try to compile even "hello world"

Error:Execution failed for task ':app:compileDebugJava'.

Cannot find System Java Compiler. Ensure that you have installed a JDK (not just a JRE) and configured your JAVA_HOME system variable to point to the according directory.

On my other mac, I dont have any problems. The setup is the same as far as I can tell. It's just that for some reason, on one machine, Android Studio / Gradle pops this error message.

I have set

JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.7.0_60.jdk/Contents/Home

running /usr/libexec/java_home gives:

/Library/Java/JavaVirtualMachines/jdk1.7.0_60.jdk/Contents/Home

running javac -version gives :

javac 1.7.0_60-ea

running java -version gives:

java version "1.7.0_60-ea"

Java(TM) SE Runtime Environment (build 1.7.0_60-ea-b15)

Java HotSpot(TM) 64-Bit Server VM (build 24.60-b09, mixed mode)

In Android Studio I have set file->other settings->default project settings-> JDK location to the JDK location listed above.

I've run out of options, why am I still getting this message?

thanks for any help, Ive wasted hours on this already.

Answer 1

My findings from an identical error proved to be due to a clash of Java Jar files that were not related with the Android studio install. Specifically the tools.jar and auskey.jar under /Library/Java/Extensions More info here

Answer 2

Rich_LogicBox solution also worked for me. I've struggled for weeks with different java versions making no difference. When I removed the jar files placed in /Library/Java/Extensions by auskey, the Android Studio error disappeared.

Answer 3

One possible solution is :

The android studio needs the jdk 1.6+ by default, but your JDK is 1.7.

You can show the package content of the Android Studio in Applications folder, and the open the info.plist , change the JVM version to your JDK's version, which is 1.7* here.

(you see, my JDK version is 1.8 in my computer)
