Summary: generate_junitxml.py fails when the content contains ANSI
escape sequences
Key: IMPALA-12045
URL: https://issues.apache.org/jira/browse/IMPALA-12045
Project: IMPALA
Issue Type: Bug
Components: Infrastructure
Affects Versions: Impala 4.3.0
Reporter: Joe McDonnell
The Impala build tries to generate JUnitXML for compilation failures. This is
currently failing with this error:

It appears to be related to ANSI escape sequences that add color to the
compilation warning output. If we strip out the ANSI escape sequences, then the
JUnitXML generation works.
Here is a thread about solutions that strip ANSI escape characters:
