问题
I've installed the Eclipse plug-in for both GWT and Appengine on 3 different machines, all with Juno (4.2). In each case, I get the following error:
"The selected App Engine SDK is not valid: Failed to initialize App Engine SDK at (path)."
Reinstalling the SDK does not make any difference. Here is more info. about the different configurations I've tried:
Ubuntu 12.0.4, Java 7, Eclipse 4.2 Mac OSX 10.8.5, Java 7, Eclipse 4.2-32 bit Mac OSX 10.8.5, Java 7, Eclipse 4.2-64 bit Mac OSX 10.6.8, Java 6, Eclipse 4.2-64 bit
Any suggestions for what may be going wrong and configs I could try? Thanks!

I was getting the error "Failed to initialize App Engine SDK at '..path'" in Eclipse 4.3(Kepler) with Google App Engine SDK 1.8.5 and Java SDK 1.7.0_01
When I updated the Java SDK to 1.7.0_41 (latest one) this error disappeared.
Great relief!!

I can confirm that using win7/sun jdk1.6.0_45/eclipse 4.2/gae sdk 1.8.4 the error occurred when updating to 1.8.5+ and that updating the jre that eclipse runs in to sun 1.7.0_45 solved the issue.
I can now add gae SDKs above 1.8.4.
I'm not sure why we could'nt have an error modal in eclipse to that effect.

I found my issue was that I was trying to use the app engine plugin for eclipse 4.3. I just downloaded the new eclipse and it works now. Sorry, thats the best I have..

I had the same problem and Nicky Jaidev's post helped me.
I had to update the Java Sdk to 1.7.
But also you have to update the eclipse.ini:
-vm C:/Program Files/Java/jdk1.7.0_45/bin/javaw.exe
If you don't change this, it will keep failing.

My guess is that the AppEngine SDK version is intended for other version of Eclipse.
For Eclipse 4.2 (Juno), use this link: https://dl.google.com/eclipse/plugin/4.2
Follow the installation guide here if you unsure about how to install plugins through Eclipse directly: https://developers.google.com/eclipse/docs/install-eclipse-4.2

I had the same issue with app engine plugin for Eclipse 4.2 (well, it was the Android Developer Tools version), on Mac OS 10.8.4.
After I saw this warning about Java 6 not being supported, https://developers.google.com/appengine/docs/java/gettingstarted/installing, I upgraded to the latest version of Java 7 and it worked.
