las dependencias del mismo módulo o entre dependencias de distintos módulos que a su vez pueden dependen entre sí (en mi caso
los conflictos entre dependencias se han dado en el mismo módulo).
En este caso, el código es un módulo que alberga varios servicios web, que están generados (los objetos y dependencias) unos con Axis y otros con CXF.
La traza generada por este conflicto de dependencias es el siguiente:

La forma de solucionarlo es mostrar las dependencias del módulo o proyecto. Si estamos utilizando maven, la orden que tendremos que ejecutar
será la siguiente:
mvn dependency:treeSi no tenemos el código compilado, podemos ejecutar para generar el arbol de dependencias:
mvn compile dependency:treeCon la sentencia anterior obtendremos una salida parecida a la siguiente:

Con los símbolos --> y <-- he han señalado las dependencias que entran en conflicto en este caso, ya que la clases contenidas enorg.apache.ws.commons.schema:XmlSchema:jar:1.4.7 ya se encuentran en org.apache.ws.xmlschema:xmlschema-core:jar:2.0.3.La forma de solucionarlo es añadiendo una etiqueta <exclusion> en el pom para evitar la inclusión de la dependencia conflictiva.
Podremos ver en el árbol de dependencias que las que entran en conflicto están en diferentes módulos, y además éstos son dependencias del módulo
que contiene los servicios web, por lo que para evitar el conflicto se excluye la que nos interese, en este caso excluímos la dependencia de Axis.
Incluyendo las siguientes entiquetas en el pom solucionaremos el problema:
<dependency>
<groupId>com.prosegur.miprosegur</groupId>
<artifactId>miprosegur-common</artifactId>
<exclusions>
<exclusion>
<groupId>org.apache.ws.commons.schema</groupId>
<artifactId>XmlSchema</artifactId>
</exclusion>
</exclusions>
</dependency>
