Liquibase 3.5 XSD gives 403 error

1

This seems to be happening recently from past few hours. The application throws up with the error:

Caused by: org.xml.sax.SAXParseException; lineNumber: 5; columnNumber: 75; schema_reference.4: Failed to read schema document 'http://www.liquibase.org/xml/ns/dbchangelog/dbchangelog-3.5.xsd', because 1) could not find the document; 2) the document could not be read; 3) the root element of the document is not <xsd:schema>.

We are also experiencing this issue. I saw that this is also reported in github Issue with https://www.liquibase.org/xml/ns/dbchangelog/dbchangelog-3.6.xsd · Issue #3183 · liquibase/liquibase · GitHub .

This should be resolved. We also highly recommend upgrading, as newer versions have a.) security fixes and b.) will find the XSD locally
