maven配置私服打包报错Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.5:compile_course

直接使用阿里云镜像仓库打包没问题，替换为私服镜像仓库后报错： 就是pom.xml中的plugin报错 ``` <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <version>3.5</version> <configuration>

IDEA中maven项目模板(archetype)选择问题，求前辈指教_course

 1.上面图片是最近学习的工程的项目结构(共12个模块)，怎么查看工程下的每个模块分别选择的什么maven结构创建的？怎么查看每个模块下的子模块是什么maven结构创建的(比如dao,service)等？ 2.如果没有办法查看的话，请问创建工程时候选择什么maven结构？工程建好后，创建一个被其他模块依赖的模块用选择什么maven结构？创建普通的maven模块用什么结构？一个模块下的不同子模块比如ihorder下的common,dao，proxy,service分别用什么maven结构创建？

idea maven聚合工程，多个模块访问路径絮乱问题，如何解决？_course

如题，练习使用聚合工程时，因为模块maven-A-web和模块maven-B-web的前端使用的js文件是一样的，所以直接 从A工程下webapp中将js文件都复制了过来，结果B里的angularJS写的app.controller（service） ，在查询service的源文件时，不会在B中查找，而是直接跳到A下的service.js文件。 工程启动后导致无法访问模块中的controller，不能正常运行功能。听人说是idea工具的问题 ，怎么破
