[INFO] Jetty server exiting.

This kind of error usually means that you have both jax-rs 1 and jax-rs 2 jars on the classpath. Jersey2 uses jax-rs 2 (javax.ws.rs-api-2.0.1. Jar), but if you still have jsr311-api.jar, it is jax-rs 1. There is a javax.ws.rs.core.application in each jar. But the jsr311 API application does not have getproperties() method (so nosuchmethoderror)

mvn d ependency:tree -Doutput=tree.txt The export dependencies are as follows:

It’s true that there are two versions of javax.ws.rs-api at the same time. After exclude, rebuild, OK
