I am attempting to build a comprehensive regex pattern to match all the an ascii tree , which is an outcome of mvn/gradle dependency representation
Note that the pattern should address the following order options
+-
| +---
| | +---
| | \---
\---
\---
This regex pattern matches but does not take ordering into consideration. Would appreciate some advice in this matter
(\|)|(\\-*)|(\+-*)

How about this:
I match the start of a line followed by zero or more spaces then the pipe with trailing spaces zero or many times followed by a plus and a dash one or many times OR a pipe with trailing spaces zero or many times followed by a backlash and a dash one or many times.
That covers all the patterns I can see in both your test case and your actual maven output.
