mvn archetype:generate does not work-no plugin found for prefix 'archetype'

I want to build a simple project using a existing archetype. But I can't run mvn archetype:generate as it keeps telling me the following information

[ERROR] No plugin found for prefix 'archetype' in the current project and in the
 plugin groups [org.apache.maven.plugins, org.codehaus.mojo] available from the
repositories [local (C:\Documents and Settings\ccen\.m2\repository), central (ht
tp://repo1.maven.org/maven2)] -> [Help 1]

I was using MS Windows and didn't use any settings.xml in my ~/.m2 folder and all stuff is brand new. Could any one help me to figure it out?

In case you are behind a coporate firewall, configure the proxy setting using settings.xml under <MAVEN_HOME>/conf directory.

Username, password, host & port values need to be provided.

<proxies>
    ...
    <proxy>
        <id>optional</id>
        <active>true</active>
        <protocol>http</protocol>
        <username>proxyuser</username>
        <password>proxypass</password>
        <host>proxy.host.net</host>
        <port>80</port>
        <nonProxyHosts>local.net|some.host.com</nonProxyHosts>
    </proxy>
</proxies>

I was banging with this problem 2 days, I checked proxy , copied settings.xml from conf folder , deleted user local .m2 folder, came out of Eclipse and installed Maven directly and tried. None of the above worked.

Finally the problem fixed by upgrading Java home from 1.7 to 1.8. My Maven version is Apache Maven 3.6.3.

Maven should report proper error for the specific issue but it is not.

Up voted the suggestion of Java upgrade in this thread, previously they were down voted.

Since Apache Maven repository URL is updated from http://repo.maven.apache.org/maven2/ to https://repo.maven.apache.org/maven2/ in NetBeans 8.2 or lower version we are facing this issue.

So what's the solution?

Solution 1:- User Terminal to download an updated maven dependencies Check out this Guide on Maven.Apache.Org

Solution 2:- Update your NetBeans, Move to Apache NetBeans 11

Had same issue and the thing that worked for me was reinstalling java

  1. sudo yum install java

  2. Find the path where java is installed, you can use which java or whereis java or sudo find / -name javac

    For me, it was /usr/lib/jvm/java-11-amazon-corretto.x86_64/bin

  3. sudo vi ~/.bashrc

  4. add below lines

    export PATH=$PATH:/usr/lib/jvm/java-11-amazon-corretto.x86_64/bin

  5. source .bashrc

and then try your command - mvn archetype:generate.

I have face the same problem when using maven 3.6.1 with jdk 1.7.40.

I hope this will help you.

If this warning is accompanied by the warning:

Received fatal alert: protocol_version

Then check your java version. I was able to solve this issue by upgrading my java version from 7 to 10. See the following:

I had same problem. Root cause: typed mvn generate:archetype instead archetype:generate.
mvn archetype:generate - is correct way.

  • To add Venerik's answer I would elaborate a bit for the naive users like me;

proxy settings in maven go to apache-maven-3.3.9\conf folder and find settings.xml open it in any text editor go to the block of code that looks like below

 <proxies>
<!-- proxy
 | Specification for one proxy, to be used in connecting to the network.
 |
<proxy>
  <id>optional</id>
  <active>true</active>
  <protocol>http</protocol>
  <username>proxyuser</username>
  <password>proxypass</password>
  <host>proxy.host.net</host>
  <port>80</port>
  <nonProxyHosts>local.net|some.host.com</nonProxyHosts>
</proxy>
-->
 </proxies>
  • Now uncomment the code from (proxy.../proxy) by cutting it and pasting it

just after (proxies).

Now change according to your proxy settings In my case it looks like the following

<proxies>
  <proxy>
      <id>optional</id>
      <active>true</active>
      <protocol>http</protocol>      
      <host>authproxy.serc.iisc.ernet.in</host>
      <port>3128</port>
      <nonProxyHosts>local.net|some.host.com</nonProxyHosts>
  </proxy>
  <!-- proxy
     | Specification for one proxy, to be used in connecting to the      network.
 |
   -->
  </proxies>

Now try running mvn archetype:generate and it should run and download

In my case the solution was just run mvn archtype:generate in Safe Mode under your user profile. After that I could run it in normal boot.

This is the issue with your firewall. To check if firewall is on:

Click Start-> click Run-> type wscui.cpl -> click OK. In Windows Security Center-> click Security If net work Network Firewall is "on" you need to set the proxy for maven.

Go to /conf -> open settings.xml with notepad uncomment proxy (if you don't remember proxy settings u can check in webbrowser u r using)

<proxies>
    <proxy>
        <id>optional</id>
        <active>true</active>
        <protocol>http</protocol>
        <username></username>
        <password></password>
        <host>www-proxy.us.oracle.com</host>
        <port>80</port>
        <nonProxyHosts></nonProxyHosts>
    </proxy>
</proxies>

You can leave the username and pwd fields blank and set only host and port.

Another problem with Windows (Vista ,Windows 7 onward) is that the command prompt should be running under Administrative privileges (Right click command prompt shortcut and choose "Run ad Administrator" if UAC is on), so simply run command prompt as Administrator before executing mvn archetype:generate.

I had faced this issue while creating vaadin 7 project under windows 7 using following command.

mvn archetype:generate -DarchetypeGroupId=com.vaadin -DarchetypeArtifactId=vaadin-archetype-application -DarchetypeVersion=7.1.8 -DgroupId=im.sma.testproject -DartifactId=testproject -Dversion=1.0 -Dpackaging=war

The other thing that could be going wrong is that your machine is behind a firewall or proxy so your box is not able to hit http://repo1.maven.org/maven2. Try accessing this URL directly in a browser or something to test if you are able to make the request.

The command you should be using to generate a project with an archetype is...

mvn archetype:generate

The command you posted in your question was wrong (missing the first 'e' in archetype). I assume this is just a typo in SO though because the error you posted had archetype spelled correctly.

I believe this error will occur if you are trying to execute this command from a directory that already has a pom.xml file in it. It will try to find an archetype plugin configuration inside the existing pom.xml file.

Try the command again in an empty directory, or at least in one that doesn't have a pom.xml file and it should work.
