maven assembly打包Error creating assembly archive pack: You must set at least one file.

问题背景：
今天maven 使用assembly插件打包spring boot项目到zip 报错
Error creating assembly archive pack: You must set at least one file.

pom插件配置如下:

  1. <plugin>
  2.                 <artifactId>maven-assembly-plugin</artifactId>
  3.                 <executions>
  4.                     <execution>
  5.                         <phase>package</phase>
  6.                         <goals>
  7.                             <goal>single</goal>
  8.                         </goals>
  9.                         <configuration>
  10.                             <finalName>${ project.artifactId}-${ project.version}-${ maven.build.timestamp}</finalName>
  11.                             <appendAssemblyId>false</appendAssemblyId>
  12.                             <descriptors>
  13.                                 <descriptor>src/assembly/assembly-descriptor.xml</descriptor>
  14.                             </descriptors>
  15.                         </configuration>
  16.                     </execution>
  17.                 </executions>
  18.             </plugin>

assembly文件如下：

  1. <assembly xmlns="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.3" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.3 http://maven.apache.org/xsd/assembly-1.1.3.xsd">

  3.     <formats>

  5.     </formats>
  6.     <includeBaseDirectory>false</includeBaseDirectory>

  11.             <outputDirectory>scripts</outputDirectory>
  12.             <includes>
  13.                 <include>*.sh</include>
  14.             </includes>
  15.             <fileMode>0755</fileMode>
  16.             <lineEnding>unix</lineEnding>
  17.         </fileSet>
  18.         <fileSet>
  19.             <directory>src/main/config</directory>
  20.             <outputDirectory>config</outputDirectory>

  23.             </includes>
  24.             <lineEnding>unix</lineEnding>
  25.         </fileSet>
  26.         <fileSet>
  27.             <directory>src/main/config</directory>
  28.             <outputDirectory>/</outputDirectory>
  29.             <includes>
  30.                 <include>apollo-portal.conf</include>
  31.             </includes>
  32.             <lineEnding>unix</lineEnding>
  33.         </fileSet>
  34.         <fileSet>
  35.             <directory>target/classes</directory>
  36.             <outputDirectory>/config</outputDirectory>
  37.             <includes>
  38.                 <include>application-github.properties</include>
  39.                 <include>apollo-env.properties</include>
  40.             </includes>
  41.         </fileSet>
  42.         <!--artifact -->
  43.         <fileSet>
  44.             <directory>target</directory>
  45.             <outputDirectory>/</outputDirectory>
  46.             <includes>
  47.                 <include>${project.artifactId}-*.jar</include>
  48.             </includes>
  49.             <fileMode>0755</fileMode>
  50.         </fileSet>
  51.     </fileSets>
  52. </assembly>

问题分析：
经过测试，发现报这个错，本质是因为你assembly配置的 fileSet中的文件一个都找不到，它没有东西能帮你打包成zip。

解决方案：
检查自己的写文件路径对不对。

我这里的原因是，pom.xml 中多了个 finalName, 生成jar命名就成了xxx.jar，我assembly配置的 fileSet的${project.artifactId}-*.jar匹配不上，导致无文件可打成zip，因而报错！

  1. <build>
  2.         <finalName>xxx</finalName>
