Answer 1

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

Answer 2

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 > Preferences > Network Connections (you may need to prefix your user name with domain eg. DOMAIN\username):

<settings>
  <proxies>
   <proxy>
      <active>true</active>
      <protocol>http</protocol>
      <host>webproxy.net</host>
      <port>8080</port>
      <username>username</username>
      <password>password</password>
      <nonProxyHosts>localhost|127.0.0.1</nonProxyHosts>
    </proxy>
   <proxy>
      <active>true</active>
      <protocol>https</protocol>
      <host>webproxy.net</host>
      <port>8080</port>
      <username>username</username>
      <password>password</password>
      <nonProxyHosts>localhost|127.0.0.1</nonProxyHosts>
    </proxy>    
  </proxies>

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".

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.

Answer 5

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)..

Answer 6

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

 <proxy>
          <id>optional</id>
          <active>true</active>
          <protocol>http</protocol>
          <username></username>
          <password></password>
          <host>10.23.73.253</host>
          <port>8080</port>
          <nonProxyHosts>local.net|some.host.com</nonProxyHosts>
        </proxy>
