quarkus: Native image build error on Win10

Describe the bug I am running on a Win10 laptop, and tried to build a native image using GraalVM CE 19.2.1 after creating a basic project from https://code.quarkus.io/ (version 1.0.0.RC1) and I get an “augmentation” error. I tried from the Windows command line and from a Git Bash, both result in the same error.

Expected behavior Well, getting a native image generated 😉

Actual behavior

To Reproduce Steps to reproduce the behavior:

1. Unzip the attached project code-with-quarkus.zip
2. Set the GRAALVM_HOME and JAVA_HOME env variables, update PATH with the updated JAVA_HOME\bin
3. Run mvnw package -Pnative

Environment (please complete the following information):

• OS: Windows 10
• Quarkus: 1.0.0.CR1
• GraalVM: 19.2.1

Additional context Setting env variables this way:

set GRAALVM_HOME=<PATH TO>\graalvm-ce-19.2.1
set JAVA_HOME=<PATH TO>\graalvm-ce-19.2.1
set PATH=%JAVA_HOME%\bin;%PATH%
