how to force maven to update local repo

Question

I compiled a jar file in one project so it can be consumed in the 2nd one  I can see the jar file in  m2 folder  But in the 2nd project it complains about artifact not found   I guess I have to force maven to update indices cache something but don t know what exactly  Any tip  thanks    Update  thanks for all good suggestions   Turns out that the maven plugin  of IntelliJ  in the second project doesn t update its index  I use command line it compiled ok

try using -U  aka --update-snapshots  when you run maven  And make sure the dependency definition is correct

Even though this is an old question  I  ve stumbled upon this issue multiple times and until now never figured out how to fix it  The update maven indices is a term coined by IntelliJ  and if it still doesn t work after you ve compiled the first project  chances are that you are using 2 different maven installations   Press CTRL Shift A to open up the Actions menu  Type Maven and go to Maven Settings  Check the Home Directory to use the same maven as you use via the command line

If you are installing into local repository  there is no special index cache update needed   Make sure that    You have installed the first artifact in your local repository properly  Simply copying the file to  m2 may not work as expected   Make sure you install it by mvn install The dependency in 2nd project is setup correctly   Check on any typo in groupId artifactId version  or unmatched artifact type classifier

If you are struggling with authenticating to a site  and Maven is caching the results  simply removing the meta-data about the site from the meta-data stash will force Maven to revisit the site   gvim  lt local-git-repository gt  commons-codec resolver-status properties
