-------------------------------------
Summary: help:effective-pom uses platform encoding and garbles
non-ascii characters, emits invalid XML
Key: MPH-87
URL: https://jira.codehaus.org/browse/MPH-87
Project: Maven 2.x Help Plugin
Issue Type: Bug
Affects Versions: 2.1.1
Environment: Windows, MacOSX, Linux, Maven 3.0.4
Reporter: Mirko Friedenhagen
As stated in http://www.w3.org/TR/REC-xml/#sec-guessing-no-ext-info XML files
without a BOM and without a XML encoding declaration should read the XML as
UTF-8.
{{help:effective-pom}} does use the platform encoding for writing the
effective-pom without emitting an appropriate XML encoding declaration in the
resulting XML file.
I have created a small sample project (available at
https://github.com/mfriedenhagen/invalidpom, attached as ZIP) which will
reproduce the issue.
While the parent pom
(https://raw.github.com/mfriedenhagen/invalidpom/master/pom.xml) has a XML
encoding declaration,
https://raw.github.com/mfriedenhagen/invalidpom/master/child-invalid/pom.xml
has none.
Now running:
{code}
mvn -s settings.xml -gs settings.xml clean validate
{code}
will produce an invalid character for the developer name "Jörg" in
{{child-invalid}}.
Two workarounds are:
* to include a XML encoding declaration as done in {{child-valid}}.
* to use {{JAVA_TOOL_OPTIONS}} on Windows as stated in
http://stackoverflow.com/a/623036/49132
* to use {{MAVEN_OPTS=-Dfile.encoding=utf-8 mvn -s settings.xml -gs
settings.xml clean validate}}.
Nonetheless I consider this a Major bug, as it clearly violates the
recommendations of W3C.
