Remove all your failed downloads   find    m2  -name    lastUpdated  -exec grep -q  Could not transfer        -print -exec rm         For windows   cd  userprofile   m2 repository for  r  i in    lastUpdated  do del  i   Then rightclick on your project in eclipse and choose Maven-  Update Project       make sure  Update Dependencies  is checked in the resulting dialog and click OK

It Happened to me also you may have  two solue tion for this   If your project consist of some external or project specificdependency in it then you have to manually add it to your M2 repo folder which is located at C  Users Mohit Singh m2 repository folder and then you have to run  mvn eclipse eclipse and then mvn clean install from the project folder if you do not have any wxternal or project sppecific dependency then you may import the project into eclipse as Existing maven project then right click on project --  GO to maven --  Click on update project a window will appear check the force snapshot download option and hit on OK

If you are behind a proxy  you have to update the settings xml file  under the conf folder of your MAVEN HOME  the file itself contains information about the proxy settings  and additionally you may need to update your Eclipse Network Settings  Window- Preferences   -  type Network Connections     Try using -X or --debug in order to get the debug output  this could provide additional information about the problem

Thanks for the replies  but after some more searching I was able to fix the problem  It turned out that I had to remove one of the    lastUpdated  which was preventing one of my plugins  Maven Surefire Plugin  from updating  I did this manually  because a maven clean wasn t doing it apparently   The problem was that the    lastUpdated  file for a plugin was blocking the maven check for updates and not allowing a necessary jar to get downloaded

The solution that work for me is the following    Copy the dependency to pom    lt dependency gt       lt groupId gt org apache maven lt  groupId gt       lt artifactId gt maven-archiver lt  artifactId gt       lt version gt 2 5 lt  version gt   lt  dependency gt   Click right on your project Select Maven Select Update project Select Force Update of Snapshots Releases

I had a similar issue with only a few projects in my workspace   Other projects with nearly identical POMs didn t have an error at all   None of the other answers listed fixed my problem   I finally stumbled upon removing re-applying the Maven nature for each project and the errors disappeared   For each project that has a pom with the  resolution will not be reattempted     error    Right-click on the project in Eclipse and select Maven- Disable Maven Nature Right-click on the project in Eclipse and select Configure- Convert to Maven Project
