[FIXED] How to remove specifics files from Maven Shaded plugin

Issue

I am trying to generate Uber Jar using maven-shade-plugin and i want to exclude some resources from the shaded jar and include some of specified artifact.But following exclude resources are bundled with it.

<dependencies>
    <dependency>
        <groupId>com.sample.auto</groupId>
        <artifactId>sample</artifactId>
        <version>1.5.0</version>
    </dependency>
    <dependency>
        <groupId>com.sample.manual</groupId>
        <artifactId>sample-manual</artifactId>
        <version>1.5.0</version>
    </dependency>
</dependencies>

                                <shadedArtifactAttached>true</shadedArtifactAttached>
                                <shadedClassifierName>jar-with-dependencies</shadedClassifierName>
                            </configuration>
                        </execution>
                    </executions>
                </plugin>
            </plugins>
        </build>
    </profile>
</profiles>

Also i need to include com.sample.auto related artifact only into my uber jar. Please let me know where i made the mistake.

Solution

The filters on the artifacts as looking into your code should ideally be:

<filters>
    <filter>
        <artifact>*:*</artifact>
        <excludes>
            <exclude>META-INF/*.SF</exclude>
            <exclude>META-INF/*.DSA</exclude>
            <exclude>META-INF/*.RSA</exclude>
            <exclude>META-INF/LICENSE</exclude>
            <exclude>LICENSE</exclude> <!--if this is same as above, not required-->
            <exclude>/*.png</exclude>
            <exclude>/*.html</exclude>
            <exclude>/*.jpeg</exclude>
            <exclude>com.myproject.auto:**</exclude> <!--to exclude all the artifacts from com.myproject.auto group-->
            <exclude>org:**</exclude><!--exclude all artifacts under group org-->
            <exclude>com.google.common:**</exclude>
        </excludes>
    </filter>
</filters>

OR in case you are looking to fine grain the classes from the dependent artifacts, then you can apply multiple filters like

<filters>
    <filter>
        <artifact>*:*</artifact>
        <excludes>
            <exclude>META-INF/*.SF</exclude>
            <exclude>META-INF/*.DSA</exclude>
            <exclude>META-INF/*.RSA</exclude>
            <exclude>META-INF/LICENSE</exclude>
            <exclude>LICENSE</exclude> <!--if this is same as above, not required-->
            <exclude>/*.png</exclude>
            <exclude>/*.html</exclude>
            <exclude>/*.jpeg</exclude>
        </excludes>
    </filter>
    <filter>
        <artifact>com.myproject.auto:*<artifact>
        <excludes>
            <exclude>com/myproject/auto/**</exclude> <!--to exclude a set of classes from the project structure-->
       </excludes>
    </filter>
    <filter>
        <artifact>org:*<artifact>
        <excludes>
            <exclude>org/**</exclude> <!--though the artifact naming needs to be refined for this-->
       </excludes>
    </filter>
    <filter>
        <artifact>com.google.common:**<artifact>
        <excludes>
            <exclude>com/google/common/**</exclude> <!--exclude classes from the respective artifacts-->
       </excludes>
    </filter>
</filters>

There are pretty useful examples to exclude-include configurations on Apache documentation as linked by you itself.
