Question

When I deploy jar, maven always add date in its file name, this make the file name repository different from the file in my local. How can I remove the date in file name ?

Thanks

About why, it’s because being it a SNAPSHOT package, each time you deploy it you are de-facto deploying a new version of it, so the timestamp is added to differentiate them in the remote repository. When Maven downloads it, it removes the timestamp because on your local repository there can only be one version, so the timestamp is useless if not confusing.

It can be removed, this site use the -DuniqueVersion=false parameter :

mvn deploy:deploy-file -Durl=file:///C:/m2-repo \
                   -DrepositoryId=some.id \
                   -Dfile=your-artifact-1.0.jar \
                   -DpomFile=your-pom.xml \
                   -DuniqueVersion=false

However, you should NOT care about artifact names, files etc.. You are using maven SO THAT you don’t have to care about them.
