Could not determine java version

[katrine]

Enonic version: 6.13.1
OS: 10.13.3

I´m working my way through the «My first app» tutorial, and got to the following step: http://docs.enonic.com/en/6.13/tutorials/my-first-app/build-and-deploy.html

When I add the command ./gradlew deploy in terminal I get the attached error message.

Is there a fix for this?

User-iMac:myapp user$ ./gradlew deploy

FAILURE: Build failed with an exception.

* What went wrong:
Could not determine java version from '9.0.4'.

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.
User-iMac:myapp user$ ./gradlew deploy --debug

Hi Katrine,

Just making sure the basics are in place:

• Did you install Java Development Kit (JDK) version 1.8 (Java 8) with update 92 or later?
• Can you echo the contents of variable $XP_HOME in your terminal?
  echo $XP_HOME

It should look like a proper path, and going to it with cd should show you the contents of the home-folder in the XP installation.
cd $XP_HOME

It can look something like this the first time you do this command:

drwxr-xr-x@ 19 bobby  staff   608B Nov  6 08:30 config
drwxr-xr-x@ 10 bobby  staff   320B Feb 12 13:58 deploy
drwxr-xr-x   4 bobby  staff   128B Apr 28  2017 repo

Looks like you have Java 9 installed, which is not supported yet.
You should download and install Java 8 to run XP.

Select the operating system that applies in this page:

http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html

Any of the “Java SE Development Kit” options should work.

We’ve updated the docs for setup of environment to reflect this. Thanks!

So when will Java 9 be supported and will we be able to use es6 syntax out of the box. Since Java 9 supports it ?

Any ETA ?

This is off-topic, what we plan to have Java 9 in XP 7.0, and then also support es6. No ETA yet, but when we know more we will communicate our plans.
