How to force maven update?

Question

I imported my already working project on another computer and it started to download dependencies.

Apparently my internet connection crashed and now I get the foll

Answer 1

Previous versions of maven did not force the check for missing releases when used -U with mvn clean install, only the snapshots, though newer version supports this.

For someone still struggling with previous version, following can be helpful-

On Windows:

cd %userprofile%\.m2\repository
for /r %i in (*.lastUpdated) do del %i

On Linux:

find ~/.m2  -name "*.lastUpdated" -exec grep -q "Could not transfer" {} \; -print -exec rm {} \;

Whenever maven can't download dependencies for any reason (connectivity/not exists etc), it will add the ".error=Could not transfer artifact" in dependency-name.lastUpdate file in respective folder under $home/.m2 directory. Removing these files will force maven to try fetching the dependencies again.
