[jira] Commented: (MRELEASE-255) during a release several elements are removed from the pom.xml (which should be left there)

Carsten Ziegeler commented on MRELEASE-255:
-------------------------------------------

I can confirm that this is still a bug - under specific circumstances the plugin removes everything before the first xml element (the intro and outro parts).

After some testing, I found some problems: the main problem is that the pom is parsed into a dom and then compared with a string version to detect the intro and outro parts. If the underlying dom implementation or the serialization from the dom to a string is altering only one single character the comparison will fail, and intro and outro is removed!

One problem I noticed are the namespace and schema definitions:

If I have the following in my pom:
<project xmlns="http://maven.apache.org/POM/4.0.0"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

everything before <project> is removed, if I use

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

(everything in one line and specific order) it works!

Imho, the current approach should be replaced with an approach which just replaces the changing elements in the pom, like a sax based approach which detects the locations and just changes them on the fly. A very simple approach would be to use an xslt stylesheet for this: it can match on the elements to change and just copy everything else. If you need help in such a solution, let me know.
