I cannot comment on the substance of the changes, that's for the YSLD moduler maintainer to do, but the Travis failure is legit, the code was not built by maven before doing the PR and has a formatting issue:

[ERROR] Failed to execute goal com.coveo:fmt-maven-plugin:2.4.0:check (default) on project gt-cql: Found 1 non-complying files, failing build -> [Help 1]

Please rebuild to apply formatting rules and fix the merge conflicts.

YSLD changes look good.

@jodygarnett what should we do about this one?

[tbarsballe]

Still failing on the same formatting issue as before:

[ERROR] Found 1 non-complying files, failing build
[ERROR] To fix formatting errors, run "mvn fmt:format"
[ERROR] Non complying file: /home/travis/build/geotools/geotools/modules/library/cql/src/test/java/org/geotools/filter/text/cql2/FilterToCQLTest.java
[INFO] STARTED build of project org.geotools.xsd:gt-xsd-gml2
[INFO] FAILURE build of project org.geotools:gt-cql

Committed the changed formatting, checking GEOT-5704 this PR confirms the issue cannot be reproduced...
