java - Maven，拒绝访问 : http://repo1. maven.org/maven2

Question

我刚刚下载了最新版本的 Maven。

当我想跑的时候

mvn archetype:generate

我收到错误信息

[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) at org.apache.maven.wagon.StreamWagon.getInputStream(StreamWagon.java:116) at org.apache.maven.wagon.StreamWagon.getIfNewer(StreamWagon.java:88) at org.apache.maven.wagon.StreamWagon.get(StreamWagon.java:61) at org.apache.maven.archetype.source.RemoteCatalogArchetypeDataSource.downloadCatalog(RemoteCatalogArchetypeDataSource.java:119) at org.apache.maven.archetype.source.RemoteCatalogArchetypeDataSource.getArchetypeCatalog(RemoteCatalogArchetypeDataSource.java:87) at org.apache.maven.archetype.DefaultArchetypeManager.getRemoteCatalog(DefaultArchetypeManager.java:216) at org.apache.maven.archetype.DefaultArchetypeManager.getRemoteCatalog(DefaultArchetypeManager.java:205) at org.apache.maven.archetype.ui.generation.DefaultArchetypeSelector.getArchetypesByCatalog(DefaultArchetypeSelector.java:200) at org.apache.maven.archetype.ui.generation.DefaultArchetypeSelector.selectArchetype(DefaultArchetypeSelector.java:71) at org.apache.maven.archetype.mojos.CreateProjectFromArchetypeMojo.execute(CreateProjectFromArchetypeMojo.java:197) at org.apache.maven.plugin.DefaultBuildPluginManager.executeMojo(DefaultBuildPluginManager.java:101) at org.apache.maven.lifecycle.internal.MojoExecutor.execute(MojoExecutor.java:209) at org.apache.maven.lifecycle.internal.MojoExecutor.execute(MojoExecutor.java:153) at org.apache.maven.lifecycle.internal.MojoExecutor.execute(MojoExecutor.java:145) at org.apache.maven.lifecycle.internal.LifecycleModuleBuilder.buildProject(LifecycleModuleBuilder.java:84) at org.apache.maven.lifecycle.internal.LifecycleModuleBuilder.buildProject(LifecycleModuleBuilder.java:59) at org.apache.maven.lifecycle.internal.LifecycleStarter.singleThreadedBuild(LifecycleStarter.java:183) at org.apache.maven.lifecycle.internal.LifecycleStarter.execute(LifecycleStarter.java:161) at org.apache.maven.DefaultMaven.doExecute(DefaultMaven.java:320) at org.apache.maven.DefaultMaven.execute(DefaultMaven.java:156) at org.apache.maven.cli.MavenCli.execute(MavenCli.java:537) at org.apache.maven.cli.MavenCli.doMain(MavenCli.java:196) at org.apache.maven.cli.MavenCli.main(MavenCli.java:141) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at org.codehaus.plexus.classworlds.launcher.Launcher.launchEnhanced(Launcher.java:290) at org.codehaus.plexus.classworlds.launcher.Launcher.launch(Launcher.java:230) at org.codehaus.plexus.classworlds.launcher.Launcher.mainWithExitCode(Launcher.java:409) at org.codehaus.plexus.classworlds.launcher.Launcher.main(Launcher.java:352) [WARNING] No archetype found in remote catalog.

我没有代理，互联网工作正常。防火墙已关闭。如何解决这个问题？

感谢您的帮助。

如果我们查看类org.apache.maven.wagon.shared.http4.AbstractHttpClientWagon方法 fillInputData( InputData inputData ) 我们可以看到:

public void fillInputData( InputData inputData )
       throws TransferFailedException, ResourceDoesNotExistException,AuthorizationException
    {
     ....
 HttpResponse response;
     ....
 statusCode = response.getStatusLine().getStatusCode();
     ....
 switch ( statusCode )
        {
            case HttpStatus.SC_OK:
                break;

            case HttpStatus.SC_NOT_MODIFIED:
                // return, leaving last modified set to original value so getIfNewer should return unmodified
                return;

            case SC_NULL:
            {
                TransferFailedException e =
                    new TransferFailedException( "Failed to transfer file: " + url + reasonPhrase );
                fireTransferError( resource, e, TransferEvent.REQUEST_GET );
                throw e;
            }

            case HttpStatus.SC_FORBIDDEN:    // <---------THIS
                fireSessionConnectionRefused();
                throw new AuthorizationException( "Access denied to: " + url + reasonPhrase);
       ....
         }
...
}

So problem caused because we have HTTP 403 Forbidden error in response.但是我不知道该怎么办...

所以现在我们知道我们收到了 FORBIDDEN 错误，因为我们在 HTTP 请求中没有 User-Agent。 Thanx to Patouche

好像是在 http://repo1.maven.org/maven2 上浏览目录已关闭。我不得不求助于自己获取原型(prototype)目录。我这样做了:

mvn archetype:generate -DarchetypeCatalog=http://search.maven.org/remotecontent?filepath=archetype-catalog.xml

或者，我想您可以从该链接下载 archetype-catalog.xml 文件并将其放置在您的 .m2 目录中，如评论中所述:
