AppEngine SDK 1.8.5 and Eclipse Juno not working

Question

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!

Answer 1

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!!

Answer 2

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.
