com.sun.org.apache.xerces.internal.dom.DocumentImpl cannot be cast to org.codehaus.plexus.util.xml.X
- by Random
Afetr using the Model library (see this) for my Maven pom.xml during this weeks I jumped on this error while attempting to write a ConfiguratonContainer into the pom.xml.
The javadoc for Model says:
public void setConfiguration(Object configuration)
Set the configuration as DOM object.
Parameters:
configuration -
So I made some xml with Document (org.w3c.dom.Document) and the xml parser standar javax library. You know the code (it's through all the net) but I paste it here...
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder parser = factory.newDocumentBuilder();
Document doc =parser.newDocument();
And then you fill the code with Element declaration,a lot of appendChild and such.
And tried to make it work. Doesn't seem to do well.
First tried using
plugin.setConfiguration(doc);
But it didn't work.
Then I tried
Obejct obj = doc;
plugin.setConfiguration(obj);
But it didn't work.
Then I searched the net for answers, and guess...
It didn't work.
There are like 0 people using this library (maven.model) in all the net. So here am I again, asking the senseis for help.
Where is my error? I have downloaded the source code of the library trying to see where is the error, but it seems to be ok (as should).
I add the stackrace for reference
