Maven - missing artifact

Question

I\'ve just moved my project from windows to linux ubuntu. After pulling files from repository it turned out that every pom.xml file consists errors. Not even one dependency

Answer 1

Ok, so you've just moved from one OS to another...

There is a big chance, that Maven settings are different, and you just forgot to move some repositories configurations, etc. to the new place.

Please check global Maven settings.xml or user-specific: ~/.m2/settings.xml on Linux and C:\User\[username]\.m2\settings.xml on Windows.

Chances are you'll find something interesting.

After fixing settings (if it's the cause), I would suggest to run Maven dependency plugin goal 'purge-loca-repository' for removing your project's dependencies from your local Maven repository and re-resolving them from scratch:

mvn dependency:purge-local-repository

Regarding aopalliance-1.0 artifact -> I haven't found it in java.net2/sonatype repositories, so please try Maven Central to resolve it:

<repository>
  <id>central</id>
  <name>Maven Central</name>
  <url>http://repo1.maven.org/maven2</url>
</repository>

Good Luck!

If you use Cntlm as autetification proxy, check if it is alive in your Windows Tasks Manager:

cntlm.exe

If not, try executing on a cmd window:

call \path_to_your_cntlm_folder\Cntlm\cntlm.exe -c \path_to_your_cntlm_folder\Cntlm\cntlm.ini

Answer 3

There are few common causes related to maven migration

• Your project consists of many internal dependencies (artifact created by yourself / colleagues) stored on your PC maven repository cache, as opposed in a shared internal repository. When you migrated into new PC it's no longer able to resolve these
• Your company has an internal maven repository (eg: nexus) and your project pom.xml isn't configured to search for this repository
• Your project is a multi module which aren't setup very neatly such that the topmost artifact in the dependecy map has to be installed first on your local repo before others can pull it
• Your new pc repository use different maven version / jdk version combinations

Your pc local repo is normally located at ~/.m2/repository
