Question

命令：

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

错误（底部的完整堆栈）：

...
[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)
    ...

我所做的每一次谷歌搜索都会得到其中一个答案，但都不适用：

在代理背后 - 但我不是代理人的背后！
2010年Maven 2.x出现了一些错误，但我正在使用Maven 3.0.5
Mangled设置文件，但我甚至没有〜/ .m2 / settings.xml文件

我检查过的其他事情：

每次我确定没有目录，也没有pom文件等
还尝试添加-DarchetypeRepository = http://repo2.maven.org/maven2但结果相同
“拒绝访问”很奇怪 - 我可以从浏览器访问repo1和repo2（虽然服务器说浏览当然已被禁用）
Mountain Lion上的Maven 3.0.5，Oracle Java 7（1.7.0_25）（OS X 10.8.4）

它确实使用一些1x模板创建了一个项目，我不知道它有多好或多坏。

Answer 1

Apache Maven团队遇到了与其中一个集成测试相同的问题，请参阅相关的message-thread。因此，似乎在8月的最后一周，策略已更改，并且在请求中没有User-Agent的情况下无法获取这些xml文件。在Maven设置中没有选项来设置此值，我也没有找到另一种方法来设置它。

我可以确认Maven-3.0.4确实有效，但此版本有security issue。根据其他帖子，其他旧版本的Maven似乎也可以使用。

除非Maven Central更改其政策，否则需要在下一个Maven版本中修复此问题。

Answer 2

我昨天得到了同样的错误。我还没有找到解决方案，但我知道为什么我们有这个错误。

在maven-archetype-plugin中挖掘了几个小时后，我没有发现一些奇怪的事情......

所以我决定再次运行相同的命令，运行tcpflow来捕获已发送的请求。结果如下：

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

Cache-store: no-store
Pragma: no-cache

Accept-Encoding: gzip

Connection: Keep-Alive

所以，Guru Meditation错误。我喜欢清漆！之后，我注意到使用netcat，如果你在请求中添加了User-Agent（任何东西），一切正常!!

[07:49][patouche@patouche-desktop:~ :) ] $ nc repo1.maven.org 80
GET /maven2/archetype-catalog.xml HTTP/1.1
Cache-control: no-cache

因此，如果您在请求中添加User-Agent，一切都会正常工作。我认为使用settings.xml但我现在还不知道。

Answer 3

似乎Apache中央存储库已经解决了这个问题。所以没有做任何改变，现在问题就解决了。如果有任何问题，请再试一次并告诉我们。

Maven：“读取原型目录时出错”，不在代理服务器后面
