maven本地打包依赖无法引用

article 2025/2/6 16:11:15

描述：写了一个RPC的starter包

执行命令后

mvn install

点击引入依赖无反应

手动输入对应的包显示找不到，但是在Maven可以找到

问题在于pom.xml文件，正常打包的maven文件应该可以显示出来，但是由于未删除spring-boot-maven-plugin。

spring-boot-maven-plugin 主要用于 Spring Boot 可执行 JAR（fat jar） 的打包和启动，它会将所有依赖合并到一个 JAR 文件中，并生成 META-INF/MANIFEST.MF，使得 java -jar xxx.jar 可以直接运行。

但 Spring Boot Starter（即 starter 依赖）只是一个 普通的依赖库（library JAR），它不需要也不应该是 可执行 JAR，

原来的pom.xml
