Peter F. Peterson commented on MCHECKSTYLE-78:
----------------------------------------------
I've determined what was generating the error. It appears that the change in
checkstyle between 2.0 and 2.1 is that it is now using validation when parsing.
The offending line:
<!DOCTYPE suppressions PUBLIC "-//Puppy Crawl/DTD Suppressions 1.0//EN"
"http://www.puppycrawl.com/dtds/suppressions_1_0.dtd";>
is now
<!DOCTYPE suppressions PUBLIC "-//Puppy Crawl//DTD Suppressions 1.0//EN"
"http://www.puppycrawl.com/dtds/suppressions_1_0.dtd";>
In case you can't see it, "Puppy Crawl/DTD" became "Puppy Crawl//DTD". The
misdiagnoses is a result of a poor error message
[INFO] ------------------------------------------------------------------------
[ERROR] BUILD ERROR
[INFO] ------------------------------------------------------------------------
[INFO] An error has occurred in Checkstyle report generation.
Embedded error: failed to load suppressions location:
/SNS/users/pf9/eclipse-workspace/sns-translation-core/src/checkstyle/suppressions.xml
Connection timed out
Which was not clear enough.
