Spotless Maven plugin changes line endings unexpectedly

[guilhermescherer]

I'm using the spotless-maven-plugin version 2.46.1 with an Eclipse formatter configuration (code_style.xml) like this:

<plugin>
    <groupId>com.diffplug.spotless</groupId>
    <artifactId>spotless-maven-plugin</artifactId>
    <version>2.46.1</version>
    <executions>
        <execution>
            <goals>
                <goal>check</goal>
                <goal>apply</goal>
            </goals>
        </execution>
    </executions>
    <configuration>
        <java>
            <eclipse>
                <file>${project.basedir}/code_style.xml</file>
            </eclipse>
        </java>
    </configuration>
</plugin>

Spotless is modifying line endings on some files when I run mvn spotless:apply.

This causes changes in files that have not been otherwise edited, making Git diffs noisy and leading to potential merge issues.
I would like Spotless to preserve the current line endings as they are in the repository and avoid rewriting files unnecessarily.

Is there a way to make Spotless respect existing line endings?

yes, with the PRESERVE mode: https://github.com/diffplug/spotless/tree/main/plugin-maven#line-endings-and-encodings-invisible-stuff
