swagger-samples/java/java-jersey2 does not compile or run
I'm running with Java 11 (maven 3.5.3) on Windows 10 host and the java-jersey2 example does not compile. I just jumped in to that example as it seemed to be a starting point for me to learn Swagger.
The doc page says to run
mvn package -Dlog4j.configuration=file:./conf/log4j.properties jetty:run
That produces a bunch of errors: Cannot find symbol javax.xml.bind.annotation and other errors.
My request is to have the documentation updated so that the steps compile and run. I know that it might be related to using newer versions of Java and maven so I'll try this with an older version of java to see if that helps. There also might be "spec/interfaces" jar file that I'm missing to support compiling, if so please let me know.
Below are details of my environment

I found the answer for how to get this to compile and run. The question/answer on StackOverflow titled Java 11 package javax.xml.bind does not exist [duplicate] provided a pointer to another question which provided the answer I needed.
The fix (for me) was to add the following dependencies to my pom.xml file from StackOverflow This is required for Java 11, and Java 10 has another potential solution (not tried).
<dependency>
<groupId>javax.xml.bind</groupId>
<artifactId>jaxb-api</artifactId>
<version>2.2.11</version>
</dependency>
<dependency>
<groupId>com.sun.xml.bind</groupId>
<artifactId>jaxb-core</artifactId>
<version>2.2.11</version>
</dependency>
<dependency>
<groupId>com.sun.xml.bind</groupId>
<artifactId>jaxb-impl</artifactId>
<version>2.2.11</version>
</dependency>
<dependency>
<groupId>javax.activation</groupId>
<artifactId>activation</artifactId>
<version>1.1.1</version>
</dependency>
This issue can be closed. I think just a comment that states that this was tested and worked with Java version 8 (likely) and later Java versions require other changes, and point to this question.
