java - Maven - Dependency on module for Checkstyle not working -

project link: https://github.com/randomquestion/multimodulemavencheckstylesample

i have simple maven project multiple modules. i'm following this maven guide enable checkstyle on it. created common module named build-tools (as per guide) , added checkstyle configuration in root pom file. i'm running weird issue.

when create new maven project scratch, mvn clean install seems work fine including checkstyle. rename checkstyle file , update pom.xml new name, build starts failing error could not find resource <new checkstyle file name>. after that, can never build again. problem seems dependency on build-tools module in root pom not working.

any suggestions on might going wrong? why mvn install not building build-tools module first?

you current setup not work! when cloned project , tried build, fail not have build-tool artifact in local repository while building parent pom.

this structure should have:

 -- build-tools   |   |   |   - pom.xml   |   - app   |   |   |   - src   |   - pom.xml   |   - pom.xml
