Please check the version number, group id and artifact id of jar you are going to use before adding it to pom.xml. It will be there as part of the metadata xml for that jar. http://search.maven.org/remotecontent?filepath=javax/json/javax.json-api/maven-metadata.xml

  <dependency>
    <groupId>javax.json</groupId>
    <artifactId>javax.json-api</artifactId>
        <version>1.0</version>
       <type>jar</type>
  </dependency>
