[MSHARED-921] NoSuchMethodError: 'Xpp3Dom.getInputLocation()' with Maven versions < 3.6.1

[jira-importer]

Hervé Boutemy opened MSHARED-921 and commented

see MSITE-863 for context

this is caused by Xpp3Dom class incompatibility with Xpp3DomUtils.mergeXpp3Dom(...):

• Xpp3Dom version is taken from Maven core classloader as exported: see http://maven.apache.org/ref/3.6.3/maven-core/core-extensions.html
• Xpp3DomUtils is taken from current plugin classloader

with recent upgrade of plexus-utils in maven-site-plugin 3.9.0, Xpp3DomUtils is a recent version (plexus-utils >= 3.2.0) that expects to merge the input location (see codehaus-plexus/plexus-utils#61)

but older Maven core versions don't have this input location field in Xpp3Dom, since they provide older plexus-utils that was upgraded to add location tracking in MNG-6597 for Maven 3.6.1

fixed in 6f06039
by shading Xpp3DomUtils class in a version that does not require the new Xpp3Dom input location tracking
