Unable to parse File 'pom.xml' ERROR is thrown while uploading jar to Business Central Artifact repository in BRMS/BPMS

Issue

• There has been a strange issue with uploading a kjar to Business Central Artifact repository in BRMS/BPMS in Linux environment . It throws the following Unable to parse File 'pom.xml' with Caused by: org.xml.sax.SAXParseException; Premature end of file as exception (as shown below) . However, in Windows environment this issue does not seem to appear and at least the upload to Business Central Artifact repository gets successfully completed. What could be the reason behind this issue and how to fix it?
