03550ab is described below
commit 03550ab565e55f509def8995c3c852b8686e80b2
Author: Alex Herbert <a.herb...@sussex.ac.uk>
AuthorDate: Sat Jun 15 18:52:44 2019 +0100
Post release fixes (#44)
* Fix checkstyle: remove tabs
* Fix checkstyle: Split long line
* Fix checkstyle: exclude pom.properties
* Update findbugs to allow deliberate fall-through
* Fix pmd: Remove ternary operator returning false
* Fix pmd: Remove implicit final
* Fix pmd: Ignore TooManyStaticImports.
This requires adding the default ruleset and then modifying with
suppressions.
* Add tests to cover use of the IOUtils class.
Requires the CSVFormat to have no quote or escape character, and the
formatted value to be a java.io.Reader.
* Clean-up findbugs exclude filter.
* Removed unused import
* Updated test comments for print tests targeting IOUtils.
* Fix checkstyle: Suppress line length warning in CSVParser.
