> Handling empty elements
> -----------------------
>
> Key: MPH-205
> URL: https://issues.apache.org/jira/browse/MPH-205
> Project: Maven Help Plugin
> Issue Type: Bug
> Components: effective-settings
> Affects Versions: 3.4.0
> Reporter: Delany
> Priority: Major
>
> When i needed a settings.xml file in the past I would copy the code from
> [https://maven.apache.org/settings.html]
> [https://maven.apache.org/ref/4.0.0-alpha-5/maven-settings/settings.html]
>
> and replace the self-closing tag of whichever section I needed - typically
> servers, mirrors and profiles. The other tags would remain, like
> "<localRepository/>"
>
> With Maven 3.9.0 the empty/self-closing tag was ignored.
>
> In Maven 4.0.0-alpha-1 the value is removed/replaced, resulting in the local
> repository directory set to ${pwd}.
> This is the case for settings.xml (what about toolchains.xml?) but not pom.xml
>
> With Maven 4.0.0-alpha-5, and I guess
> https://issues.apache.org/jira/browse/MNG-7678
> the behaviour has changed back to that of Maven 3 - an empty tag is simply
> ignored, it doesn't override.
> But while the build is successful, mvn help:effective-settings now fails with
> {noformat}
> Execution default-cli of goal
> org.apache.maven.plugins:maven-help-plugin:3.4.0:effective-settings failed:
> Cannot invoke "org.codehaus.plexus.util.xml.Xpp3Dom.getDom()" because
> "configuration" is null{noformat}
