                </plugin>
            </plugins>
        </pluginManagement>
    </build>
</project>

在demo-client-persist内部我依赖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？

【问题讨论】：

恐怕调试这将需要整个父级和demo-client-persist POM；这看起来像是dependencyManagement 中的范围问题。另请注意，除assembly:single 之外的所有目标均已弃用。
@chrylis 更新了父组件和模块 pom。
über父pom:ppdf-3party-demo的内容是什么？它有dependencyManagement 部分吗？
当您使用SNAPSHOT 版本时是否包含spring-jdbc？

【解决方案1】：

在一开始的构建过程中可能会出现错误，说明由于此错误，传递依赖项已被禁用。

【讨论】：

【解决方案2】：

运行mvn assembly:assembly 时可能会忽略某些警告。

## [WARNING] Invalid POM for ${group}:${artifact}:${type}:${version}, transitive dependencies (if any) will not be available, enable debug logging for more details
 ##

您可以使用选项“-X”运行 maven 以查看详细信息。在我的情况下，通过删除本地 maven 缓存 (~/.m2) 中的 _remote.repositories 文件来解决问题

您可能想看看这篇文章："The POM for ... is missing, no dependency information available" even though it exists in Maven Repository
