Maven command line throwing ArrayIndexOutOfBoundsE

I'm new to Maven and installed 3.5.0 in Windows 64 bit machine. I have added Avro dependency in pom.xml as specified in https://avro.apache.org/docs/1.8.2/gettingstartedjava.html. I am facing Build failure and getting ArrayIndexOutOfBoundsException when doing mvn clean compile from the command line:

Below is the pom.xml file which I am using:

See https://issues.apache.org/jira/browse/MNG-6216 for all the details.

In short: while downloading the pom, the file got corrupt. For some reason extra content is added after the closing tag, making it not a valid xml file. Maven 3.3.9 and before ignored all data afterwards, 3.5.0 is more strict. There are 2 simple solutions: remove your local repository or use maven 3.3.9

Where's still looking for the cause of this issue. It is probably there for a long time but it was never an issue.

You could check the pom of avro, because that one is causing the issue or one of its dependencies.
