File name encoding in jar

Question

My maven run creates different files in the target directory and compresses them into the jar file.

In case special characters like an Ü exist in the file names, the file names in the jar archive are not correctly encoded and showed as Ü. (The file contents are not affected)

As the files are correctly shown in the target directory, the issue must be caused by maven's jar:jar.

The interesting thing is that if I use the unzip command in Linux, the files are extracted with correct name, if I use Windows Explorer or 7zip in Windows, the names are not correct.

I had the exact same problem and upgrading my maven-war-plugin version solved the problem I think you should do the same with your maven jar plugin

        <plugin>
            <artifactId>maven-war-plugin</artifactId>
            <version>3.0.0</version>
            <configuration>
                <attachClasses>true</attachClasses>
                <classesClassifier>classes</classesClassifier>
            </configuration>
        </plugin>
    </plugins>
