From the error message it looks your maven-metadata.xml file is corrupteed. so if you open this file C:\Users\NOKIA_ADMIN.m2\repository\us\nok\mic\hrm\portal\portlet\basic-details-nok-form-portlet\maven-metadata-local.xml you should find \u0 at the start of the first line. that is not allowed as it is outside the start tag. you may just remove these additional characters then try again, or delete the whole maven-metadata-local.xml file as it is inside .m2 folder and will be auto generated when you run your mvn command again.
