conflict in Maven settings.xml with Closure Compiler

[myphysicslab]

The instructions for building Closure Compiler with Maven state that it is necessary to "Add sonatype snapshots repository to ~/.m2/settings.xml". After creating this file I get errors when building Dossier.

[13:34:49 ~/Documents/Programming/js-dossier]$ ./gendossier.sh 
INFO: Starting clean (this may take a while). Consider using --expunge_async if
the clean takes more than several minutes.
ERROR: /Users/erikn/Documents/Programming/js-dossier/lib/maven/BUILD:94:1: no
such package '@gson//jar': Errors interpreting settings file: [[WARNING]
Unrecognised tag: 'id' (position: START_TAG seen ...<profiles>\n    <id>...
@14:9)  @ /Users/erikn/.m2/settings.xml, line 14, column 9] and referenced by
'//lib/maven:gson'.
ERROR: Loading failed; build aborted.
INFO: Elapsed time: 0.151s
ERROR: Couldn't start the build. Unable to run tests.

I tried changing the settings.xml to be more like what is shown at https://maven.apache.org/settings.html but I only got more similar errors.

If I disable that settings.xml file by renaming it to "XXXsettings.xml" then Dossier builds no problem.  But that doesn't seem like a great long term solution.

Here is the latest version of my settings.xml file.

<?xml version="1.0" encoding="UTF-8"?>

Your settings are malformed. Should have <profiles><profile>....

Confirmed, works now. Thanks.
