idea maven 多module工程怎么关联源码而不是关联本地仓库的jar?报错
如图所示，新建了一个简单的工程，结构为：
wrap
-main 依赖mod工程
-mod
配置没问题，但在main工程里配置了jetty插件运行就会 报错，找不到mod这个依赖的jar
[ERROR] Failed to execute goal on project main: Could not resolve dependencies for project com.kongwu:main:war:1.0: Failure to find com.kongwu:mod🏺1.0 in https://repo.maven.apache.org/maven2 was cached in the local repository, resolution will not be reattempted until the update interval of central has elapsed or updates are forced -> [Help 1]

https://developer.aliyun.com/profile/5yerqm5bn5yqg?spm=a2c6h.12873639.0.0.6eae304abcjaIB其实没父目录的maven工程是有问题的。这边公司是这样的。
正确的做法是
root
|-web
|-service
|-dao
这些模块中都有pom。然后root中配置好pom后。在各个子系统中加点依赖就行了。
你可以新建project,选maven,然后一路下去。
建设好的工程中，在添加module，选择父节点为root,然后添加好子工程。
最后一个编译就OK了

是我哪里弄错了么，还是idea就这么设计的嗯。我也是这么做的，但是jetty:run之后他就报错找不到依赖module的jar。。应该会找依赖项目的文件才对吧？pom.xml里面配置啊···依赖这个子模块我已经配置好了，但运行的时候他还是去本地仓库找mod这个jar，而不找模块的源码添加项目依赖。（这个只是保证编译时不报错）
另外还要在子POMMOD中，加入一句这个
< parent > < groupId >父GROUPID </ groupId > < artifactId >父ARTIFACTID </ artifactId > < version >父版本 </ version > < relativePath >../mod/pom.xml </ relativePath > </ parent >把mod移动和wap同级，然后修改mod中的pom代码如上。工程如下这样：
怎么做到没有父目录，把这个移动到上层目录的。。。还有这一步有什么用呢引用来自“szwx855”的评论
其实没父目录的maven工程是有问题的。这边公司是这样的。
正确的做法是
root

回复 @空无:jetty是必须打包的。这个木有办法。所以我都用resin或者tomcat.这个jetty，在本地开必debug很蛋疼。回复 @szwx855:我换了几个环境换了电脑都是同样的结果，经测试，直接配置个本地tomcat是可以正常依赖module的，junit/main方法运行也是可以依赖的，但mavenjetty/tomcat插件跑的话就必须先把module打包到本地仓库，还是很感谢你！回复 @空无:一般是加载本地仓库的jar,在idea中看代码跟踪到jar的时候，因为它会自动反编译，所以这个时候，你点下这个ｃｌａｓｓ右上上角的downloadsource，然后在选择chooseSource，就定位到源码了。都有的，你的可以正常加载代码而不是本地仓库的jar吗？你看本地仓库有没有对应的jar，你删掉在看看2020-06-09 10:15:55赞同 展开评论 打赏
