>          Issue Type: Bug
>    Affects Versions: 3.2.1
>            Reporter: Tobias Oberlies
>
> Steps to reproduce the problem:
> # Use the following settings.xml (replacing the URLs with valid URLs in your environment):
> {noformat}
> <settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
>    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
>    xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd">
>    <mirrors>
>       <mirror>
>          <id>mirror1</id>
>          <url>http://nexus:8081/nexus/content/repositories/releases/</url>
>          <mirrorOf>
>             external:*, !snapshots.repo
>          </mirrorOf>
>       </mirror>
>    </mirrors>

>       <profile>
>          <id>use-snapshots-repo</id>
>          <pluginRepositories>
>             <pluginRepository>
>                <id>snapshots.repo</id>
>                <url>http://nexus:8081/nexus/content/repositories/snapshots/</url>
>             </pluginRepository>
>          </pluginRepositories>
>          <repositories>
>             <repository>

>       </profile>
>    </profiles>
>    <activeProfiles>
>       <activeProfile>use-snapshots-repo</activeProfile>
>    </activeProfiles>
> </settings>
> {noformat}
> # Set up a project which uses an artifact from {{snapshots.repo}} which is not available in the local Maven repository
> # Build the project: The build fails because Maven only tries to download from the releases repository.
> Expected behaviour: Maven should have used the snapshots repo.
> The root cause of the problem is that whitespaces around the separators in the {{mirrorOf}} configuration are not trimmed. When changing the configuration to
> {noformat}
>          <mirrorOf>
>             external:*,!snapshots.repo
>          </mirrorOf>
> {noformat}
> the snapshots repository is used and the build passes.
