How to resolve conflict in maven dependencies apache: commons-fileupload 1.3.2 and commons-io 2.5 - maven

Question

I have developed an app using jhipster generator. I have only slightly changed the pom.xml file. I needed the commons file-upload to be able to receive multipart requests. I am not sure but i believe that was the only change i have made.
I have only noticed the maven build problems when started trying to build the production image.
My IntelliJ uses bundled maven 2 and it works fine there, but when I switch back to maven 3 bundled or installed in my operating system (windows 7 x64) I receive this error.

I believe one of the reasons my be conflict in my dependencies.
Here is snapshot of intelij analysis of my pom.xml.
[edit 1]
I have gave up trying to resolve this error. So what i tried to do now is to generate a new project with jhipster and copy all custom elements that was created by me into it.
And here i stumbled on a problem, which is i cant really do that, uperantly i have upgraded the jhipster-generator package incorrectly somewhere in the past.
So now on freshly generated projects i receive the same error + in my webapp bunch of files has an error like "ng-jhipster has no exported class AlertService" or the same but instead of AlertService its EventManager or some other class but it`s always the same package. Yes tried upgrading it.
I have found similar classes with Jhi prefixes on them in #ngx-jhipster package so it seams to me as as generator uses classes for one version of jhipster and package.json, pom.xml for another.
I tried upgrading the jhipster-generator, yarn and yo, removing the jhipster-generator dependency altogether and adding them back again, and generating projects again. Nothing worked =(
