[MPH-205] Handling empty elements
Delany opened MPH-205 and commented
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
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
Affects: 3.4.0
