[jetty-users] Classes scanned from multiple locations with Maven plugin

[James Srinivasan <james.srinivasan@xxxxxxxxx>]

I'm trying to use jetty-maven-plugin to run some integration tests
with failsafe, but getting lots of warnings similar to the following
with mvn install, or mvn jetty:start (but *not* with mvn jetty:run):

[WARNING] my.package.api.LinksApi scanned from multiple locations:
file:///path/to/my/project/my-project-1.0-SNAPSHOT/WEB-INF/classes/my/package/api/LinksApi.class,
file:///path/to/my/project/my-project/target/classes/my/package/api/LinksApi.class

and

[WARNING] com.sun.xml.fastinfoset.AbstractResourceBundle scanned from
multiple locations:
jar:file:///path/to/my/homedir/.m2/repository/com/sun/xml/fastinfoset/FastInfoset/1.2.16/FastInfoset-1.2.16.jar!/com/sun/xml/fastinfoset/AbstractResourceBundle.class,
jar:file:///C:/path/to/my/project/target/my-project-1.0-SNAPSHOT/WEB-INF/lib/FastInfoset-1.2.16.jar!/com/sun/xml/fastinfoset/AbstractResourceBundle.class

I've tried to solve this with:

<artifactId>maven-failsafe-plugin</artifactId>
<version>2.6</version>
<configuration>
    <useManifestOnlyJar>false</useManifestOnlyJar>
    <useSystemClassLoader>false</useSystemClassLoader>
</configuration>
[...]

and scanClassesPattern, scanTestClassesPattern, scanTargetPatterns in
jetty-maven-plugin

and adding javax.servlet as `provided` to my dependencies

But none of this has helped. Given the jars should all have the same
version, it doesn't appear critical but any help would be much
appreciated. I don't see why my local maven repo is on my servlet's
classpath.

My full pom.xml is here:

Thanks in advance,
