问题
I've seen several discussions on the net about how great it would be to have an XML schema or DTD for logback.xml file to have at least the very basic validation and auto-completion in IDEs like IDEA or Eclipse, but I never saw any solution.
Did you?
回答1:
It is not supported officially according to the documentation, but there is an independent project to provide Schema for Logback
However, due to extreme flexibility of the Logback configuration, Schema cannot support all possible configuration options.
回答2:
As of June 2011, the official documentation states
As shall become clear, the syntax of logback configuration files is extremely flexible. As such, it is not possible specify the allowed syntax with a DTD file or an XML Schema.
There was a brief thread on the topic, but didn't seem to go anywhere.

Just to get rid of the annoying warning in Eclipse add <!DOCTYPE xml> after <?xml version="1.0" encoding="UTF-8"?>.
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE xml>
回答4:
The independent project mentioned by Sergey covered most of my requirements.
However, some elements were missing, I added them on my own fork on on https://github.com/nkatsar/logback-XSD. Hope they will get merged in the main project.

A slightly different answer that allows eclipse autocomplete is:
<?xml version="1.0" encoding="UTF-8"?>
<configuration xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://www.padual.com/java/logback.xsd"
debug="true" packagingData="true" scan="true" scanPeriod="30 seconds">
