在里面demo-client-persist我有依赖spring-jdbc
<parent>
<groupId>edu.i2r</groupId>
<artifactId>ppdf-3party-demo-client</artifactId>
<version>1.0</version>
</parent>
<artifactId>demo-client-persist</artifactId>
<name>demo-client-persist</name>
<url>http://maven.apache.org</url>
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
</properties>
<dependencies>
<dependency>
<groupId>edu.i2r</groupId>
<artifactId>demo-client-model</artifactId>
<version>1.0</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-jdbc</artifactId>
<version>3.1.1.RELEASE</version>
</dependency>
<dependency>
<groupId>edu.i2r</groupId>
<artifactId>ppdf-demo-common</artifactId>
<version>1.0</version>
</dependency>
</dependencies>
</project>
最后，我有以下程序集描述符
<includeBaseDirectory>false</includeBaseDirectory>
<dependencySets>
<dependencySet>
<outputDirectory>lib</outputDirectory>
<scope>runtime</scope>
</dependencySet>
</dependencySets>
<fileSets>
运行mvn assembly:assembly，输出目录似乎工作，因为依赖项被复制到 lib 目录。但是，只有 spring-jdbc jar 不存在。
我错过了什么吗？
