Cloud shell Java version older than app engine

[E EE]

App engine for java is using Java 8 runtime, but cloud shell is still on Java 7. This means it cannot be used for compiling and deploying app engine apps that actually use Java 8.

Not technically a bug, but I think all the parts of the platform should be version compatible.

Hi,

Actually the GA version of App Engine Standard for Java is Java 7.  Java 8 is currently in a limited alpha.  Java 8 is also available for App Engine Flexible.

Java 8 is available in Cloud Shell by entering:

sudo update-java-alternatives -s java-1.8.0-openjdk-amd64

Actually the documentation is all Java 8 with no mention of Java 7.

If you go to this page:

https://cloud.google.com/appengine/docs/

And expand the "Flexible Environment" node on the left the only Java version listed is 8.

Same with app.yaml:

https://cloud.google.com/appengine/docs/flexible/java/configuring-your-app-with-app-yaml

"You can select the Java 8 / Jetty 9.3 Runtime or the Java 8 Runtime."

You are correct, since the App Engine Flexible environment is capable of hosting any runtime via Docker, the Java image offered in the documentation uses the newer Java 8 (just as Les stated). 

To reiterate Les' comment, the App Engine Standard Java runtime on the other hand is at Java 7. You can also request to have Java 8 on the Standard runtime which is currently available during the Alpha signup.
