背景:

pom.xml 里面 plugin 的配置如下:

<plugin>
                        <groupId>org.apache.maven.plugins</groupId>
                        <artifactId>maven-assembly-plugin</artifactId>
                        <version>3.1.1</version>
                        <configuration>
                            <finalName>${project.artifactId}</finalName>
                            <appendAssemblyId>true</appendAssemblyId>
                            <descriptors>
                                <descriptor>src/main/assembly/client-jar.xml</descriptor>
                            </descriptors>
                        </configuration>
                        <executions>
                            <execution>
                                <id>make-assembly</id>
                                <phase>package</phase>
                                <goals>
                                    <goal>single</goal>
                                </goals>
                            </execution>
                        </executions>
                    </plugin>

`src/main/assembly/client-jar.xml` 配置如下:

<assembly xmlns="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.2"
              xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
              xsi:schemaLocation="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.2 http://maven.apache.org/xsd/assembly-1.1.2.xsd">
        <id>client</id>
        <formats>
            <format>jar</format>
        </formats>
        <includeBaseDirectory>false</includeBaseDirectory>
        <fileSets>
            <fileSet>
                <directory>target/classes</directory>
                <includes>  
                    <include>**/embedclient/**</include>
                    <include>**/model/**</include>  
                </includes> 
                <outputDirectory>${file.separator}</outputDirectory>
            </fileSet>
        </fileSets>
    </assembly>

执行命令 `mvn assembly:single` 的时候出现下面错误:

在网上收了半天没有发现有 `archive cannot be empty` 相关错误， 后面想着 `存档不能为空` 是不是没有相关 class 文件的原因，先执行一下 clean 和 compile，再执行 assembly 就好了，具体命令:

mvn clean
    mvn compile
    mvn assembly:single
