如何告诉Checkstyle检查所有行中的换行符/换行符LF而不是CRLF? [英] How to tell Checkstyle to check all lines for linefeed / newline LF and not CRLF?

问题描述

有没有一种方法可以检查文件是否仅使用LF而在检查样式中没有使用CRLF，反之亦然?

Is there a way to check if the file is using LFs only and no CRLFs or vice versa in checkstyle?

我发现的唯一支票是

NewlineAtEndOfFile

但是我只搜索文件末尾的内容吗?

But I search for more as only at the end of the file?

推荐答案

仅用于补充Michal Kordas的好答案.

以下是经过稍微修改的配置，它将仅与第一个错误的换行符匹配，并且也禁止Mac OS行尾(CR):

Below is a slightly modified configuration, which will only match the first wrong newline and forbid also the Mac OS Line Endings (CR):

<module name="RegexpMultiline">
    <property name="format" value="(?s:(\r\n|\r).*)"/>
    <property name="message" value="CRLF and CR line endings are prohibited, but this file uses them."/>
</module>
