嗨,我已经下载并安装了一个最干净的nexus服务器(刚刚删除了公共访问).然后我像这样改变了我的maven settings.xml settings xmlns="http://maven.apache.org/SETTINGS/1.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSc
<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0
http://maven.apache.org/xsd/settings-1.0.0.xsd">
<mirrors>
<mirror>
<id>xx</id>
<name>xx</name>
<url>http://some.host:8081/nexus/content/groups/allrepos/</url>
<mirrorOf>*</mirrorOf>
</mirror>
</mirrors>

</server>
</servers>
</settings>
..主机和用户混淆的地方:-)
最后我删除了.m2 / repository / *中的所有内容并输入以下内容：
mvn archetype:generate -DgroupId=home.my.scratch -DartifactId=HelloWorld -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false
这将给我一个问题“[警告]无法检索org.apache.maven.plugins的插件描述符：maven-clean-plugin：2.4.1：”错误但在.m2 / repository目录中有一些文件和文件夹再次.因此主机和访问应该正常工作.
这是完全堆栈：

我错过了什么？
Failed to retrieve plugin descriptor for org.apache.maven.plugins ………
您的nexus存储库未配置为从maven central检索插件.指定< mirrorOf> *< / mirrorOf>时,它希望在其存储中找到插件.因此,当你安装一个干净的nexus服务器时,它开始在nexus本身内搜索maven插件的描述符,而它们位于maven central.
要解决此问题,您必须定义插件存储库以重新路由所有请求以检索maven插件到maven central.
为此,请编辑settings.xml并在配置文件中添加以下代码段.
....
<pluginRepository>
<id>central</id>
<!-- This can be any URL -->
<!-- even something like 'http://central/' will work fine -->
<url>http://repo1.maven.org/maven2/</url>
<releases>
<enabled>true</enabled>
<updatePolicy>never</updatePolicy>
</releases>
<snapshots>
<enabled>true</enabled>
<updatePolicy>always</updatePolicy>
</snapshots>
</pluginRepository>
....
编辑
URL条目可以是任何虚假URL(它不必是任何有效的URL),因为当镜像设置被定义为< mirrorOf> *< / mirrorOf>时,它将始终通过nexus重新路由.
....
<pluginRepository>
<id>central</id>
<url>http://central/</url>
<releases>
<enabled>true</enabled>
<updatePolicy>never</updatePolicy>
</releases>
<snapshots>
<enabled>true</enabled>
<updatePolicy>always</updatePolicy>
</snapshots>
</pluginRepository>
