What steps will reproduce the problem?

1. Post diffs of a java maven project inside a clearcase repo

2. Go to server.com/reviewboard/r/530/diff/
What is the expected output? What do you see instead?

Filenames of diff are correct.

"MavenProject/src/main/java/package/Filename.java"

instead the diff file name ends behind src

"MavenProject/src"
For files in the test folder it works "MavenProject/src/test/java/package/FilenameTest.java"

Error in ReviewBoard-2.0.15-py2.7.egg\reviewboard\scmtools\clearcase.py

# This regular expression can extract from extended_path
# pure system path. It is construct from two main parts.
# First match everything from beginning of line to first

# numbers (file version).
# This patch assume each branch present in extended_path

# called "main" in path.
UNEXTENDED = re.compile(r'^(.+?)/|/?(.+?)/main/?.*?/([0-9]+|CHECKEDOUT)')

As mentioned in the comment, this path is not expected to contain a "/main".
For Maven projects a src/main/java folder is required!
Fix

As mentioned in line 74-80:

    ClearCase paths contain additional informations about branch

    and file version preceded by @@/main/. This function remove this

    parts from ClearCase path to make it more readable

    For example this function convert extended path::
   /vobs/comm@@/main/122/network@@/main/55/sntp
   @@/main/4/src@@/main/1/sntp.c@@/main/8

to the the to regular path::

Clearcase not only add the /main it adds @@/main
Therefore checking the regex for @@/main fixes the problem.

Then, in the line 96 we can get rid of the replace.('@@','').
