(IntelliJ IDEA Version: 2017.3.4) Build: Sync => Could not determine java version from '9.0.4'.

Hi guys, I'm working through 'Spring Basics' at the mo. I've downloaded and installed intelliJ. After starting a new project with Gradle as instructed - the build sync fails as follows:

"Could not determine java version from '9.0.4'."

The set-up was all as default as far as i'm aware. I'd be really grateful for any help or pointers. thanks, Ash :)

Go to Gradle - wrapper - gradle-wrapper.properties change the Url distribution link to this for example, distributionUrl=https://services.gradle.org/distributions/gradle-4.3.1-all.zip We must update the gradle version to the most recent one.

Hi there,

Having a quick Google around this issue, it looks as though you need to upgrade your Gradle version.

There's some info on the issue here.

Good luck!

Steve.

Thanks very much for the reply Steve. Unfortunately, I have actually tried this but it appears i'm already on the most current version.

=> gradle 4.6 already installed

The only way i could get intelliJ working in the end was by uninstalling Java 9 and replacing it with 8. Thanks for your help Steve :)

That's not really a solution, is it? I wonder why IntelliJ haven't got a patch to fix this.

Other, unhelpful, threads are suggesting reverting to Java 8, rather than using 9. I don't see that as a solution, though! I'll keep looking ...

There are a few links in here that might be useful.
