Maven: "Error reading archetype catalog", NOT behind a Proxy

Question

Command:

mvn archetype:generate -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false -DgroupId=org.apache.solr -DartifactId=es-my-proj

Error (full stack at bottom):

...
[INFO] --- maven-archetype-plugin:2.2:generate (default-cli) @ standalone-pom ---
[INFO] Generating project in Batch mode
[WARNING] Error reading archetype catalog http://repo1.maven.org/maven2
org.apache.maven.wagon.authorization.AuthorizationException: Access denied to: http://repo1.maven.org/maven2 , ReasonPhrase:Denied Access.
    at org.apache.maven.wagon.shared.http4.AbstractHttpClientWagon.fillInputData(AbstractHttpClientWagon.java:928)
    ...

Every google search I've done comes up with one of these answers, but none of which are applicable:

• Behind a proxy - but I'm not behind a proxy!
• Some bug back in 2010 with Maven 2.x, but I'm on Maven 3.0.5
• Mangled settings file, but I don't even have a ~/.m2/settings.xml file

Other things I've checked:

• Each time I make sure there's no directory and no pom file, etc.
• Also tried adding -DarchetypeRepository=http://repo2.maven.org/maven2 but same result
• The "Access denied" was odd - I am able to visit both repo1 and repo2 from a browser (though the server says browsing has been disabled of course)
• Maven 3.0.5, Oracle Java 7 (1.7.0_25), on Mountain Lion (OS X 10.8.4)

It does create a project using some 1x template, I don't know how good or bad that is.

Answer 1

The Apache Maven team faced the same issue with one of their integration-tests, see the related message-thread. So it seems that during the last week of August the policy has changed and it is not possible to get these xml files without a User-Agent in the request. There's no option in the Maven Settings to set this value, neither have I found another way to set it.

I can confirm that Maven-3.0.4 does work, but this version has a security issue. According to other posts other older versions of Maven seem to work as well.

Unless Maven Central changes its policy, this is something which needs to be fixed in the next Maven release.

Answer 2

It seems like Apache central repository has fixed the issue. So without making any change, the problem is fixed now. Please try once again and let us know in case of any issue.

Answer 3

I got the same error yesterday. I didn't finish to find the solution yet but I have a idea why we have this errror.

After hours of digging in the maven-archetype-plugin, I didn't notice something strange...

So i decide to run the same command again with a tcpflow running to capture the sended request. Here is the result :

192.168.000.010.59775-185.031.016.185.00080: GET /maven2/archetype-catalog.xml HTTP/1.1

So, a Guru Meditation error. I like Varnish !! After that, I notice using netcat that, if you add a User-Agent (anything) in the request, everything works fine !!

So, if you add a User-Agent in the request, everything will work. I thinks with the settings.xml but I don't know how for now.
