前面講到assembly在unpack和repackage的過程中不會merge相同名字的檔案而是直接忽略，所以會導致一些問題，所以我們最後選擇了可以通過檔案merge功能的shade plugin，實現如下：

     <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-shade-plugin</artifactId>
            <version>2.4.3</version
 
>
            <executions>
                <execution>
                    <phase>package</phase>
                    <goals>
                        <goal>shade</goal>
                    </goals>
                    <configuration>
                        <finalName
 
>executable</finalName>
                        <shadedArtifactAttached>true</shadedArtifactAttached>
                        <shadedClassifierName>Shaded</shadedClassifierName>
                        <shadedTestJar>true</shadedTestJar>
                        <transformers
 
>
                            <transformer implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
                                <mainClass>com.cloud.....PublisherTest</mainClass>
                            </transformer>
                            <transformer implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
                                <resource>META-INF/spring.handlers</resource>
                            </transformer>
                            <transformer implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
                                <resource>META-INF/spring.schemas</resource>
                            </transformer>
                            <transformer implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
                                <resource>META-INF/spring.tooling</resource>
                            </transformer>
                        </transformers>
                    </configuration>
                </execution>
            </executions>
        </plugin>

不過這種方式，我需要把test class，test resouce放到main中，因為shade打包的時候不包含test相關的東西。
