remove file from jar-with-dependencies with maven assembly plugin

Question

I use maven-assembly-plugin version 3.1.1 to make a jar with all dependencies included. I want to exclude my application.yml however I am unable to remove it from jar.

pom.xml :

             <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-assembly-plugin</artifactId>
                <version>3.1.1</version>
                <configuration>
                    <descriptors>
                        <descriptor>env/assembly/descriptor.xml</descriptor>
                    </descriptors>
                </configuration>
                <executions>
                    <execution>
                        <id>make-assembly</id>
                        <phase>package</phase>
                        <goals>
                            <goal>single</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>

my descriptor.xml:

<assembly xmlns="http://maven.apache.org/ASSEMBLY/2.1.0"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xsi:schemaLocation="http://maven.apache.org/ASSEMBLY/2.1.0 http://maven.apache.org/xsd/assembly-2.1.0.xsd">
    <id>test</id>
    <formats>
        <format>jar</format>
    </formats>
    <includeBaseDirectory>false</includeBaseDirectory>
    <dependencySets>
        <dependencySet>
            <outputDirectory>/</outputDirectory>
            <useProjectArtifact>true</useProjectArtifact>
            <unpack>true</unpack>
            <scope>compile</scope>
            <excludes>
                <exclude>
                    application.yml
                </exclude>
            </excludes>
        </dependencySet>
    </dependencySets>
    <fileSets>
        <fileSet>
            <outputDirectory>/</outputDirectory>
            <directory>${project.build.outputDirectory}</directory>
            <excludes>
                <exclude>
                    application.yml
                </exclude>
            </excludes>
        </fileSet>
    </fileSets>
</assembly>

result :

The following patterns were never triggered in this artifact exclusion filter:
o  'application.yml'

If instead of application.yml i use the * pattern all file are well removed.

I have tried to put the absolute path but it change nothing :

        <excludes>
            <exclude>
                env/dev/conf/application.yml
            </exclude>
        </excludes>

Also the exclude in my fileSets seam useless.

Also tried this pattern in fileSets and dependencySet but application.yml still include :

         <exclude>
            **/application.yml
        </exclude>

solution that worked, I forgot to add the unpackOptions in the assembly file :

pom.xml :

    <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-assembly-plugin</artifactId>
        <version>3.1.1</version>
        <executions>
            <execution>
                <id>make-jar</id>
                <phase>package</phase>
                <goals>
                    <goal>single</goal>
                </goals>
                <configuration>
                <descriptors>
                    <descriptor>env/assembly/descriptor.xml</descriptor>
                </descriptors>
                </configuration>
            </execution>
        </executions>
    </plugin>
