Easier setup for a Spring Boot project with Angular. All the steps are from https://github.com/dsyer/spring-boot-angular.
Simply drop the spanc folder and spring_angular.sh script in the root folder of your Spring project and run spring_angular.sh. If the procedure were to mess up your pom.xml you can find a backup in the spanc folder under the name of old_pom.xml.
You can verify the installation running you program with mvn spring-boot:run and checking http://localhost:8080/.
After the installation, ypu can delete the spanc folder and spring_angular.sh.
I'm using Maven Frontend Plugin v1.9.1 and Node v13.14.0.
You can change the version editing the files pom1.txt and pom2.txt.
