问题
My xml validation is failing with the following reason:
Failed to execute goal se.ericsson.jcat.ebs:xml-validation-plugin:1.0.2:validate (default) on project ebs-extensions: Unable to execute mojo: While parsing /home/xchoshu/latestWorkspace/ebs-extensions/src/main/resources/log4j2.xml, at file:/home/xchoshu/latestWorkspace/ebs-extensions/src/main/resources/log4j.xsd, line 18, column 64: src-resolve.4.1: Error resolving component 'ConfigurationType'. It was detected that 'ConfigurationType' has no namespace, but components with no target namespace are not referenceable from schema document 'file:/home/xchoshu/latestWorkspace/ebs-extensions/src/main/resources/log4j.xsd'. If 'ConfigurationType' is intended to have a namespace, perhaps a prefix needs to be provided. If it is intended that 'ConfigurationType' has no namespace, then an 'import' without a "namespace" attribute should be added to 'file:/home/xchoshu/latestWorkspace/ebs-extensions/src/main/resources/log4j.xsd'. -> [Help 1]
my xds looks like:
<?xml version="1.0" encoding="UTF-8"?>

xsi:schemaLocation="http://logging.apache.org/log4j/2.0/config https://ei-switching.rnd.ki.sw.ericsson.se/browser/jcat-bsp/log4j.xsd">
<Appenders>
<Console name="JCATDefaultConsoleAppender" target="SYSTEM_OUT"
follow="true">
<PatternLayout pattern="%d{default} %m [%t] %l%n%ex{full}" />
</Console>
</Appenders>
<Loggers>
<Root level="INFO">
<AppenderRef ref="JCATDefaultConsoleAppender" />
</Root>
</Loggers>
can anyone help me in correcting the xsd. TIA

回答1:
The XSD is missing the namespace declaration xmlns="http://logging.apache.org/log4j/2.0/config". That makes the XSD valid.
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns="http://logging.apache.org/log4j/2.0/config"
targetNamespace="http://logging.apache.org/log4j/2.0/config"
elementFormDefault="qualified"
attributeFormDefault="unqualified">
<xs:element name="Configuration" type="ConfigurationType"/>
But then your XML files has lots of issues
You are missing the mandatory elements Properties and ThresholdFilters and Appenders should contain at least 1 Appender (not a Console)
A Sample document would look something like this
<?xml version="1.0" encoding="utf-8"?>
