The Checkstyle rules file could not be parsed. #607

Closed JThompson-scottlogic closed 1 year ago

JThompson-scottlogic commented 1 year ago

When trying to read from a custom xml:

Document root element "module", must match DOCTYPE root "null".
            The file has been blocked for 60s.

config file:

<?xml version="1.0"?>

<module name="Checker">
    <module name="TreeWalker">
        <module name="AvoidStarImport" />
        <module name="AvoidNestedBlocks" />
        <module name="EmptyBlock"/>
        <module name="EmptyCatchBlock"/>
        <module name="LeftCurly"/>
        <module name="NeedBraces"/>
        <module name="RightCurly"/>
        <module name="DesignForExtension"/>
    </module>
</module>

This happens with the real Checkstyle JAR, so it's not a plugin issue.

$ java -jar checkstyle-10.8.1-all.jar -c test.xml .
