I have fixed this problem by configuring tomee-maven-plugin
<groupId>org.apache.openejb.maven</groupId>
<artifactId>tomee-maven-plugin</artifactId>
<version>${tomee-maven-plugin.version}</version>
<extensions>true</extensions>
<configuration>
....
<libs>
<lib>com.thoughtworks.xstream:xstream:${xstream-version}</lib>
</libs>
....
</project>
Thank you for your interest
