Przesiadka z Intellij do Eclipse = problemy z JRE

0

Potrzebuję pomocy w konfiguracji projektu. Prosta RESTowa apka.

Build path specifies execution environment JavaSE-1.8. There are no JREs installed in the workspace that are strictly compatible with this environment.

Mam Javę SE jaki RE 9.

 java version "9.0.1"
 Java(TM) SE Runtime Environment (build 9.0.1+11)
 Java HotSpot(TM) 64-Bit Server VM (build 9.0.1+11, mixed mode)

Wszystko mam tak jak autor tutoriala. Trochę musiałem się namęczyć z dodaniem pewnym dependecies w pom.xml bo brakowało. W screenie warning z błędu.

Odpalenie serwera wywala wyjątki

javax.servlet.ServletException: Servlet.init() for servlet [Jersey Web App] threw exception
java.lang.IllegalArgumentException

Możesz spróbować jeszcze pozmieniać wersję Javy na 8, może to coś pomoże.

Niestey zmiana na 8 nic nie dała. Robię już 5 podejście. Ściągam JARy których brakuje w Eclipse żeby odpalić projekt. Kod wygląda tak

Nie znam się wybitnie na Jersey ale patrząc na: https://stackoverflow.com/questions/4412147/the-resourceconfig-instance-does-not-contain-any-root-resource-classes wynika, że brakuje Ci:

<init-param>
  <param-name>com.sun.jersey.config.property.packages</param-name>
  <param-value>your.package.name</param-value>
</init-param>

Już dodałem po wrzuceniu tutaj logów. GitHub: https://github.com/enseitankad0/REST

Trzeba dokładnie przepisywać, bo potem się traci czas - swój i innych.
