   ./gradlew -Dorg.gradle.java.home=/path/to/java/11/home shadowJar

   • Windows

   gradlew.bat -Dorg.gradle.java.home=/path/to/java/11/home shadowJar

2. Run:

   • Docker (8080):

Implementation notes:

• The same data model is used in all layers for simplicity;
• JSR 303: Bean Validation should be considered instead of custom solution;
• In-memory data store is used for simplicity;
• Event consumer and producer applications are in the same process for simplicity;
• Balance reservation is omitted for simplicity
