Maven pack directory with html files into jar

Question

I have a simple web app with following structure:

I need to pack it into a jar . Here's my pom.xml:

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

                    <archive>
                        <manifest>
                            <mainClass>main.Main</mainClass>

                    </archive>
                </configuration>
            </plugin>
        </plugins>

        <resources>
            <resource>
                <directory>templates</directory>
                <includes>
                    <include>page.html</include>
                </includes>
            </resource>
        </resources>

    </build>

    <dependencies>
        <dependency>
            <groupId>org.freemarker</groupId>

        </dependency>

    </dependencies>

</project>

I pack it with Maven 's assembly:single option:

But when I run my app with java -jar server.jar and pass a request in browser I get:

java.io.FileNotFoundException: Template "templates/page.html" not found.

This happens because a folder templates with page.html in it is not added to jar - I unpacked server.jar searched for it, but didn't find.

I googled a lot something like "maven pack resources into jar" or "maven pack html into jar". And the most close article to my issue was: https://maven.apache.org/plugins/maven-resources-plugin/examples/include-exclude.html

I followed instructions in that article - added <resources> and rest tags where I outlined my folder and a file that I want to include in jar (please see it in pom.xml that I wrote above).

But still this folder and page.html aren't added.

Please guide me, what I'm doing wrong and how to add templates folder with page.html in it in jar .

在我的情况下，spring框架在SRC下具有资源文件夹...。并且该资源文件夹包含模板文件夹。

Src->resource -> template
