Failed to load devfile in OCP 4.1 instance (as in #222) but in che.openshift.io it loaded OK from https://raw.githubusercontent.com/redhat-developer/codeready-workspaces/f02980e0699a57c86672b0e60abcb5a579bc9a0a/dependencies/che-devfile-registry/devfiles/03_java11-quarkus/devfile.yaml

We should probably tweak the sample project so the README.md doesn't mention JDK1.8+ (as the CRW version is for JDK11.0.6 embedded in GraalVM). Or use a different sample project?

WDYT @svor ?

I tried native compilation in this devfile and got an error

[ERROR] Failed to execute goal io.quarkus:quarkus-maven-plugin:1.1.1.Final:native-image (default) on project getting-started: Failed to generate a native image: Failed to augment application classes: Build failure: Build failed due to errors
[ERROR]         [error]: Build step io.quarkus.deployment.pkg.steps.NativeImageBuildStep#build threw an exception: java.lang.IllegalStateException: Unsupported version of GraalVM detected: GraalVM Version 19.3.1 CE. Please use GraalVM 19.2.1.

In https://github.com/quarkusio/quarkus/wiki/Migration-Guide-1.3 As I see GraalVM JDK 11 is a tech preview for now. So probably it isn't stable right now.
Also I found related issue quarkusio/quarkus#5682
And Quarkus guide says that we need GraalVM version 19.2.1 - https://quarkus.io/guides/building-native-image#prerequisites.

So probably for now we have to use Java-8 and GraalVM-19.2.1 to provide native compilation

[nickboldt]

Hmm, odd. https://github.com/quarkusio/quarkus/wiki/Migration-Guide-1.2 doesn't mention that JDK 11 is tech preview (and that's the version we have in the plugin registry).

But since Stevan has said that native isn't something we NEED for 2.1, I've opened https://issues.redhat.com/browse/CRW-611 as a future work item for Che 7.10+/CRW 2.2+.

I'm thinking I could remove the c++ stuff and reduce the container by a further 60MB. Or leave it because it's already over 690M :D

[tsmaeder]

@nickboldt since @svor did the upstream plugin, he's a much better reviewer than me. I can't request him, though.

[nickboldt]

But you could have assigned it to him?

[nickboldt]

graalvm & c/c++ stuff removed. openjdk 11 added.
