If anyone still wants to use jms1.1 then add the public jboss repository and maven will find it...
project->dependencies:
<dependencies>
<dependency>
<groupId>javax.jms</groupId>
<artifactId>jms</artifactId>
<version>1.1</version>
</dependency>
project->repositories:
<repositories>
<repository>
<id>repository.jboss.org-public</id>
<name>JBoss.org Maven repository</name>
<url>https://repository.jboss.org/nexus/content/groups/public</url>
</repository>
It works -
F:\mvn-repo-stuff>mvn verify
