[jira] [Commented] (MCHECKSTYLE-384) Incompatibility to Checkstyle version >= 8.24

["Benjamin Marwell (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/MCHECKSTYLE-384?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16996322#comment-16996322 ] 

Benjamin Marwell commented on MCHECKSTYLE-384:
----------------------------------------------

I do not think that you can blame the {{maven-checkstyle-plugin}}. If you update the checkstyle plugin, either
 * update the {{checkstyle.xml}} file you use or
 * use a lower dependency of puppycrawl checkstyle.
Here's a how to: [https://maven.apache.org/plugins/maven-checkstyle-plugin/examples/upgrading-checkstyle.html]
 * Also, the maven-checkstyle site  says: "This version of the plugin uses Checkstyle 8.19 by default" – is this not true anymore?

So, that said, what do you expect from the maven plugin? I just did take a look in the source code. maven checkstyle plugin indeed uses {{<checkstyleVersion>8.19</checkstyleVersion>}} by default. That said, the problem you reported must come from a configuration you did yourself. Maybe you did declare a newer checkstyle version somewhere?

Can you please elaborate more details? Otherwise I'd say this is "not an issue".
