idea 一个多maven项目聚合

其他 2019-01-12 13:23:03 阅读次数: 0

今天突然下回顾以下Maven的聚合项目搭建，因为我们平时大多都是公司已经搭好的项目，平时自己也知道原理，但有时不去实践一下，你根本不知道，你是否会。

我有时候会比较膨胀，觉得这也没什么跟着网上文章搭建一下就好了，应该就能成功，没必要去搭建，但经历告诉我，实践出真知，比空头下要好多了


搭建的时候没遇到多少问题，唯一碰到的问题就是

[ERROR] Failed to execute goal on project Mavens-service: Could not resolve dependencies for project com.wm:Mavens-service:jar:1.0-SNAPSHOT: Failed to collect dependencies at com.wm:Mavens-core:jar:1.0-SNAPSHOT: Failed to read artifact descriptor for com.wm:Mavens-core:jar:1.0-SNAPSHOT: Could not find artifact com.wm:Mavens-parent:pom:1.0-SNAPSHOT -> [Help 1]
[ERROR] 
[ERROR] To see the full stack trace of the errors, re-run Maven with the -e switch.
[ERROR] Re-run Maven using the -X switch to enable full debug logging.
[ERROR] 
[ERROR] For more information about the errors and possible solutions, please read the following articles:
[ERROR] [Help 1] http://cwiki.apache.org/confluence/display/MAVEN/DependencyResolutionException


先声明一下，我这个项目构建是这样的：
主：Mavens-parent

子：Mavens-core,Mavens-service,Mavens-web


这里Mavens-service依赖Mavens-core，Mavens-core 我已经install 进仓库了，为什么还会报这样的错误呢

通过查找，最终是找到了解决方法，是因为我还没有安装Mavens-parent导致，安装完Mavens-parent后在进行Mavens-service的安装就没有问题了。



在此，我顺便记录一下几个pom文件

这里介绍一下父类里的dependencyManagement 是子类可以继承，但要在需要用到里面包的子类，引入这个包，但是不需要填写version或其他配置，父类都配置好了。

如：

 <dependency>
            <groupId>com.wm</groupId>
            <artifactId>Mavens-core</artifactId>
        </dependency>

父类里直接写在dependencys里的子类都会继承下来
