Cannot create Maven Project in eclipse

Question

I have Eclipse Luna and Maven 3 2 3 installed on a Windows 7 machine behind a corporate firewall    Trying to create a project from an archetype results in the following error      Could not resolve archetype org apache maven archetypes maven-archetype-quickstart RELEASE from any of the configured repositories         Could not resolve artifact org apache maven archetypes maven-archetype-quickstart pom RELEASE        Failed to resolve version for org apache maven archetypes maven-archetype-   quickstart pom RELEASE    Could not find metadata org apache maven archetypes maven-archetype-quickstart maven-metadata xml in local  C  Users xxxx m2 repository         Failed to resolve version for org apache maven archetypes maven-archetype-quickstart pom RELEASE  Could not find metadata org apache maven archetypes maven-archetype-quickstart maven-metadata xml in local  C  Users xxxx m2 repository      Proxy details are configured in  m2 settings xml and generating a maven project from an archtype works fine in command line    I tried to apply the solutions from here but none worked  The remote catalog is not acessible as well  I reckon it s a problem with the network settings of Eclipse  I also looked at this bug report to try and find some clues and couldn t really understand how to implement the workaround    here is my settings xml file    lt settings xmlns  http   maven apache org SETTINGS 1 0 0    xmlns xsi  http   www w3 org 2001 XMLSchema-instance    xsi schemaLocation  http   maven apache org SETTINGS 1 0 0                       http   maven apache org xsd settings-1 0 0 xsd  gt       lt servers gt           lt server gt               lt id gt nexus lt  id gt               lt username gt xxxx xxxx com lt  username gt               lt password gt  XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX  lt  password gt           lt  server gt           lt server gt               lt id gt deployment lt  id gt               lt username gt xxxx xxxx com lt  username gt               lt password gt  XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX  lt  password gt           lt  server gt       lt  servers gt       lt mirrors gt           lt mirror gt           lt  --This sends everything else to  public -- gt           lt id gt nexus lt  id gt           lt mirrorOf gt   lt  mirrorOf gt           lt url gt https   nexus-int xxxx xxxx com nexus content groups public lt  url gt           lt  mirror gt       lt  mirrors gt       lt profiles gt           lt profile gt           lt id gt nexus lt  id gt               lt  --Enable snapshots for the built in central repo to direct -- gt           lt  --all requests to nexus via the mirror -- gt           lt repositories gt               lt repository gt                   lt id gt central lt  id gt                   lt url gt http   central lt  url gt                   lt releases gt  lt enabled gt true lt  enabled gt  lt  releases gt                   lt snapshots gt  lt enabled gt true lt  enabled gt  lt  snapshots gt               lt  repository gt           lt  repositories gt           lt pluginRepositories gt               lt pluginRepository gt                   lt id gt central lt  id gt                   lt url gt http   central lt  url gt                   lt releases gt  lt enabled gt true lt  enabled gt  lt  releases gt                   lt snapshots gt  lt enabled gt true lt  enabled gt  lt  snapshots gt               lt  pluginRepository gt           lt  pluginRepositories gt           lt  profile gt       lt  profiles gt       lt activeProfiles gt           lt  --make the profile active all the time -- gt           lt activeProfile gt nexus lt  activeProfile gt       lt  activeProfiles gt   lt  settings gt    Any ideas   Thanks  Tomer

It worked for   I just removed  archetypes  folder from below location  C  Users Lenovo m2 repository org apache maven  But you may change following for experiment - download latest binary zip of Maven  add to you C   drive and change following            Change Proxy    lt proxy gt             lt id gt optional lt  id gt             lt active gt true lt  active gt             lt protocol gt http lt  protocol gt             lt username gt  lt  username gt             lt password gt  lt  password gt             lt host gt 10 23 73 253 lt  host gt             lt port gt 8080 lt  port gt             lt nonProxyHosts gt local net some host com lt  nonProxyHosts gt           lt  proxy gt

I had the same error show up while creating the project but I wasn t behind a proxy and hence the above solutions did not work for me    I found this forum  It suggested to         Delete or Rename  m2 directory from your HOME directory      In Windows - C  Users  lt username gt  Windows   OR   In Linux -  home  lt username gt          restart the Eclipse   STS spring tool suite  which am using       It worked

It s actually easy and straight forward   just navigate to your  m2 folder    m2 repository org apache maven  inside this maven folder  you will see a folder called Archetypes    delete this folder and the problem is solved   but if you don t feel like deleting the whole folder  you can navigate into the archetype folder and delete all the archetype you want there  The reason why it keeps failing is because  the archetype you are trying to create is trying to tell you that she already exists in that folder  hence move away     summarily  deleting the archetype folder in the  m2 folder is the easiest solution

Same problem here  solved   I will explain the problem and the solution  to help others   My software is   Windows 7 Eclipse 4 4 1  Luna SR1  m2e 1 5 0 20140606-0033      from eclipse repository  http   download eclipse org releases luna    And I m accessing internet through a proxy   My problem was the same    Just installed m2e  went to menu  File   New   Other   Maven   Maven project   Next   Next  Selected  Catalog  All catalogs  and  Filter  maven-archetype-quickstart   then clicked on the search result  then on button Next  Then entered  Group Id  test gr  and  Artifact Id  test art   then clicked on Finish button  Got the  Could not resolve archetype     error    After a lot of try-and-error  and reading a lot of pages  I ve finally found a solution to fix it  Some important points of the solution    It uses the default  embedded  Maven installation  3 2 1 1 5 0 20140605-2032  that comes with m2e  So no aditional  external  Maven installation is required  No special m2e config is required    The solution is    Open eclipse  Restore m2e original preferences  if you changed any of them   Click on menu  Window   Preferences   Maven   Restore defaults  Do the same for all tree items under  Maven  item  Archetypes  Discovery  Errors Warnings  Instalation  Lifecycle Mappings  Templates  User Interface  User Settings  Click on  OK  button  Copy  for example to a notepad window  the path of the user settings file  To see the path  click again on menu  Window   Preferences   Maven   User Settings  and the path is at the  User settings  textbox  You will have to write the path manually  since it is not posible to copy-and-paste  After coping the path to the notepad  don t close the Preferences window  At the Preferences window that is already open  click on the  open file  link  Close the Preferences window  and you will see the  settings xml  file already openned in a Eclipse editor  The editor will have 2 tabs at the bottom   Design  and  Source   Click on  Source  tab  You will see all the source code  xml   Delete all the source code  Click on the code  press control a  press  del   Copy the following code to the editor  and customize the uppercased values       lt settings gt     lt proxies gt      lt proxy gt         lt active gt true lt  active gt         lt protocol gt http lt  protocol gt         lt host gt YOUR PROXY IP OR NAME lt  host gt         lt port gt YOUR PROXY PORT lt  port gt         lt username gt YOUR PROXY USERNAME  OR EMPTY IF NOT REQUIRED  lt  username gt         lt password gt YOUR PROXY PASSWORD  OR EMPTY IF NOT REQUIRED  lt  password gt         lt nonProxyHosts gt YOUR PROXY EXCLUSION HOST LIST  OR EMPTY  lt  nonProxyHosts gt       lt  proxy gt     lt  proxies gt   lt  settings gt      Save the file  control s  Exit Eclipse  Menu File   Exit  Open in a Windows Explorer the path you copied  without the filename  just the path of directories   You will probaly see the xml file   settings xml   and a directoy   repository    Remove the directoy   repository    Right click   Delete   Yes  Start Eclipse  Now you will be able to create a maven project   File   New   Other   Maven   Maven project   Next   Next  select  Catalog  All catalogs  and  Filter  maven-archetype-quickstart   click on the search result  then on button Next  enter  Group Id  test gr  and  Artifact Id  test art   click on Finish button    Finally  I would like to give a suggestion to m2e developers  to make config easier  After installing m2e from the internet  from a repository   m2e should check if Eclipse is using a proxy  Preferences   General   Network Connections   If Eclipse is using a proxy  the m2e should show a dialog to the user   m2e has detected that Eclipse is using a proxy to access to the internet  Would you like me to create a User settings file  settings xml  for the embedded  Maven software     Yes     No     If the user clicks on Yes  then m2e should create automatically the  settings xml  file by copying proxy values from Eclipse preferences

I GOT THIS problem too  and I solved it finally  this is the solution      go to windows-- preference-- maven-- user settings   Change the settings xml path to a valid path    The path maybe not under  m2 directory  in your home directory

If you re behind a proxy  the very first thing to do is  add settings xml with proxy configs under C  Users  username   m2 folder  and replicate same proxy configs under Window  gt  Preferences  gt  Network Connections  you may need to prefix your user name with domain eg  DOMAIN username     lt settings gt     lt proxies gt      lt proxy gt         lt active gt true lt  active gt         lt protocol gt http lt  protocol gt         lt host gt webproxy net lt  host gt         lt port gt 8080 lt  port gt         lt username gt username lt  username gt         lt password gt password lt  password gt         lt nonProxyHosts gt localhost 127 0 0 1 lt  nonProxyHosts gt       lt  proxy gt      lt proxy gt         lt active gt true lt  active gt         lt protocol gt https lt  protocol gt         lt host gt webproxy net lt  host gt         lt port gt 8080 lt  port gt         lt username gt username lt  username gt         lt password gt password lt  password gt         lt nonProxyHosts gt localhost 127 0 0 1 lt  nonProxyHosts gt       lt  proxy gt         lt  proxies gt    Delete C  Users  username   m2 repository folder as well

I am using Spring STS 3 8 3  I had a similar problem  I fixed it by using information from this thread And also by fixing some maven settings  click  Spring Tool Suite -  Preferences -  Maven and uncheck the box that says  Do not automatically update dependencies from remote depositories  Also I checked the boxes that say  Download Artifact Sources  and  download Artifact javadoc

In my case following solution worked    Delete RELEASE directory  amp  resolver-status properties file in your local Maven repository under directory  m2    maven-archetype-quickstart  Create Maven project in Eclipse or STS  Spring Tool Suite   It will automatically download quickstart archetype  amp  work as expected    I hope this may help someone

For me the solution was a bit simpler  I just had to clean the repository    m2 repository org apache maven archetypes
