错误：运行eclipse的Google插件需要jdk1.7或更高版本

Question

I have been trying to make this work all day long but there seems to be no end to my frustration. I want to use Google App Engine for my android application. I have downloaded the jdk 1.7 u51 but still whenever i start the eclipse ADT, a dialog box appears saying that jdk 1.6 is in use; jdk 1.7 or higher needs to be installed. I have set the path in the preference to jre inside the jdk 1.7. Also, the app engine SDK path shows the error "Failed to initialize App Engine SDk[path]". I have referred all the threads here and over the internet relating to this issue and have tried all the proposed solutions but to no avail. Any help would be greatly appreciated.

versions eclipse 4.2(ADT) JDK 1.7u51 App Engine SDK 1.8.9

Answer 1

Try uninstalling the old java version, and making sure that the latest version is the only one installed. Another problem might be if you have a 64-bit computer, you may have the older version installed to one program files, but Eclipse is looking through the x86 program files and not finding the correct version(or vice-versa). You may also want to set your PATH and CLASSPATH.

Type

java -version

javac -version

into the command prompt, and it will return with what Java you have installed. If all else fails, try reading https://developers.google.com/appengine/docs/java/gettingstarted/installing for more information and see what went wrong.

Answer 2

You must have matching architecture for Eclipse and JDK. If you are using 32-bit eclipse, then use 32-bit JDK else use 64-bit versions of both.

Everything else will fall in place automatically

Answer 3

I am using Indigo and found this forum thread to do the trick.

To your eclipse.ini file add

-vm
/Library/Java/JavaVirtualMachines/jdk1.7.0_WHATEVERTHESUFFIXIS/Contents/Home/jre/lib/server/libjvm.dylib

Note the suffix "lib/server/libjvm.dylib" which is not what you use for later versions of Eclipse. (For them you link to "bin/java".) This needs to be above any "-vmargs" flags in eclipse.ini.
