Generator-jhipster: Java 11 LTS support?

[anthony-o]

Overview of the feature request

As JDK 8 will go end of support on December 2020, the current LTS for JDK is now 11.

I saw that JHipster is planned to support every LTS but is currently not supporting 11 whereas it has been released on September 2018 (it's not that long ago though ;) ).

Motivation for or Use Case

Support every LTS JDK.

it seems to me that jhipster will support jdk 11 when spring boot 2.1 will be released

Yes but we first need to wait for Spring Boot to support Java 11... That will be with Spring Boot 2.1, and then we'll start the work (no worries - I'm closing this but it's on our roadmap, of course).

FYI I'm using Java 10 on https://start.jhipster.tech so there shouldn't be much issue.

BTW we need help for this, so if you're ready to contribute, don't hesitate to join us.

Hi there;
Am testing my generated app with Java 11 and it works without problems.
just update pom like this :

1. Java version : <java.version>11</java.version>
2. Spring Boot version : <spring-boot.version>2.1.2.RELEASE</spring-boot.version>
3. Add jaxb dependencies :

        <dependency>
            <groupId>org.glassfish.jaxb</groupId>
            <artifactId>jaxb-runtime</artifactId>
            <version>2.3.2</version>
        </dependency>

1. Comment or Remove maven-enforcer-plugin requireJavaVersion rule.
2. mvn clean build

My Env : Windows 10 64-bit, OpenJDK 11.0.1 64-bit, Apache Netbeans 10, Maven 3.5.2, Spring Boot 2.1.2.RELEASE

1. Comment or Remove **maven-enforcer-plugin requireJavaVersion** rule.

2. mvn clean build

My Env : Windows 10 64-bit, OpenJDK 11.0.1 64-bit, Apache Netbeans 10, Maven 3.5.2, Spring Boot 2.1.2.RELEASE

This doesn't work for me. Not sure what I am doing wrong. I have followed the exact same steps but I get the following error.

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.8.0:compile (default-compile) on project user-service: Fatal error compiling: java.lang.NoClassDefFoundError: javax/xml/bind/JAXBException: javax.xml.bind.JAXBException -> [Help 1]

This won't work well until we migrate to Spring Boot 2.1, so that will be for JHipster 6.
