If you ve configured a repository in your maven s settings xml  check if you ve access to it   When I had this problem  there were enterprise repositories configured in settings xml but I was out of the company

In my case I m using an external maven installation with m2e  I ve added my proxy settings to the external maven installation s settings xml file  These settings haven t been used by m2e even after I ve set the external maven installation as default maven installation   To solve the problem I ve configured the global maven settings file within eclipse to be the settings xml file from my external maven installation   Now eclipse can download the required artifacts

JackDev s option 3 works for me after I changed the default repository to another folder   Below is what I see after M2E plugin automatically download the maven-resources-plugin-2 6  Maybe this could give you some hint if you want to take the manual approach  The necessary files can be downloaded from here  https   repo maven apache org maven2 org apache maven plugins maven-resources-plugin 2 6

Try to delete all dirs in  usr share maven-repo - of course then maven will die so you must re-install and try again  In my case re-install from maven ver 3  to maven2 with deleting all repositories helped   I tried by deleting all from  m2 but that didn t help

User · Answer

Hopefully I m not late for the party   Encountered this using Eclipse Kepler and Maven 3 1   The solution is to use a JDK and not a JRE for your Eclipse project   Make sure to try maven clean and test from eclipse just to download missing jars

User · Answer

If your working at a company  they may be preventing you from downloading outside software and installing it  You may need to install the plugins manually or repoint to an internal mirror repository

In addition to what  JackDev replies  what also solved my problem was to  1  Install the jdk under directory with no spaces   C  Java   Instead of   C  Program Files Java   This is a known issue in Windows  I fixed JAVA HOME as well  2  Install maven as in Java case  under C  Maven  Fixed the M2 HOME accordingly    3  I java 7 and java 8 on my laptop  So I defined the jvm using eclipse ini  This is not a mandatory step if you don t have -vm entry in your eclipse ini  I updated   C  Java jdk1 7 0 79 jre bin javaw exe   Instead of   C  Java jdk1 7 0 79 bin javaw exe   Good luck

My problem was the location of the config file   In eclipse settings  Windows- preferences- maven- User Settings  the default config file for maven points to C  users  yourUser   m2 settings xml  If you unzip maven and install it in a folder of your choice the file will be inside  yourMavenInstallDir  conf   thus probably not where eclipse thinks  mine was not   If this is the case maven won t load correctly  You just need to set the  User Settings  path to point to the right file

I had the same problem but with an other cause  The solution was to deactivate Avira Browser Protection  in german Browser-Schutz   I took the solusion from m2e cannot transfer metadata from nexus  but maven command line can  It can be activated again ones maven has the needed plugin

Most people will tell you to check your proxy settings or delete and re-add artifacts  but I will stay away from that and give another suggestion in case that doesn t turn out to be your problem  It could be your mirror settings   If you use maven at the office then there s a good chance maven is configured to look for your company s internal maven repository  If you re doing some work from home and you are not connected to the network this could be the problem  An obvious solution might be VPN to the office to get visibility to this repo  Another way around this is to add another mirror site to your  User  m2 settings xml file so if it fails to find it on your office network it will try public repo    lt mirror gt       lt id gt Central lt  id gt       lt url gt http   repo1 maven org maven2 lt  url gt       lt mirrorOf gt central lt  mirrorOf gt       lt  -- United States  St  Louis-- gt   lt  mirror gt    For other maven repositories take a look here  http   docs codehaus org display MAVENUSER Mirrors Repositories

Couple of things to try     Doublecheck the location of the local artifact repo configured in your settings xml file  at the following location  your home folder   m2 settings xml   Are you sure the local repo is where you think it is    Yes  a mistake I ve made in the past     Remove entire contents of artifact repo on the new build machine  or at least anything related to Maven    You mentioned doing some artifact repo cleanup but I m not sure what directory ies  you removed   I ve run into weird issues like these when a jar was corrupted  Make sure you have enough disk space quota for the local artifact repo   I have run into weird issues when I didn t have a large enough quota to hold all the artifacts  likely caused by partially downloaded jar files  Try running with plain Maven on the command line  take Eclipse and m2e out of the equation   mvn -U dependency resolve should do it   The -U forces Maven to download no matter what your repository update policies are   Add -X to get detailed debug logging  Copy settings xml from MAVEN HOME conf  to USER HOME m2  Add proxies  if needed  in case you are behind a proxy server

User · Answer

A more subtle reason for this could be a Settings xml file which has a space in the first line before the doctype

It appears that there can be a lot of different causes for this issue   I experienced it after installing a new version of Eclipse  Luna    Command-line maven worked fine  but Eclipse had build issues   I use a Certificate Authority in my JRE  This is important because this provides my authentication when downloading Maven resources   Even though my project was pointing to the appropriate JRE inside of Eclipse - Eclipse was running using a different JRE  this is apparent looking at the Java process properties in Windows task manager    My solution was to add the following in my eclipse ini and explicitly define the JRE I want to use   -vm C  Program Files Java jdk1 7 0 51 bin javaw exe

What I found out is that while m2e is looking for v2 5 by default  my local repo has 2 6 and no 2 5   Without going into investigation of how this came about simply adding the dependency to pom solved the problem    lt dependency gt       lt groupId gt org apache maven plugins lt  groupId gt       lt artifactId gt maven-resources-plugin lt  artifactId gt       lt version gt 2 6 lt  version gt   lt  dependency gt    This can be removed after running a build once

Some files where missing at your local repository  Usually under   user home   m2 repository   Neets answer solves the problem  However if you dont want do download all the dependencies to your local repository again you could add the missing dependency to a project of yours and compile it   Use the maven repository website to find the dependency  In your case http   mvnrepository com artifact org apache maven plugins maven-resources-plugin 2 5 was missing   Copy the listed XML to the pom xml file of your project  In this case    lt dependency gt       lt groupId gt org apache maven plugins lt  groupId gt       lt artifactId gt maven-resources-plugin lt  artifactId gt       lt version gt 2 5 lt  version gt   lt  dependency gt    Run mvn compile in the root folder of the pom xml  Maven will download all missing dependencies  After the download you can remove the added dependency   Now you should be able to import the maven project or update the project without the error

I had the exact same problem and since I read somewhere that the error was caused by a cached file  I fixed it by deleting all the files under the  m2 repository folder   The next time I built the project I had to download all the dependencies again but it was worth it - 0 errors
