为什么我在Maven中会出现“401未授权”错误？

Question

为什么我在Maven中会出现“401未授权”错误？

以下是调用mvn deploy（底部为完整日志）时出现的错误：

[INFO]生成失败
[ERROR]无法执行目标org.apache.maven.plugins：maven-deploy-plugin:2.7:在项目上部署（default-deploy）xbnjava:无法部署项目：无法传输项目com.github.aliteralmind：xbnjava:pom:0.1.2 from/to sonatype-nexus-staging(https://oss.sonatype.org/service/local/staging/deploy/maven2/):无法传输文件：https://oss.sonatype.org/service/local/staging/deploy/maven2/com/github/aliteralmind/XBNJava/0.1.2/XBNJava-0.1.2.pom。返回代码为：401,ReasonPhrase：未授权.->[帮助1]

根据这个sonatype支持页面：

“如果您收到401，那是因为maven发送了错误的登录凭据，或者根本没有凭据。”

下面是我采取的步骤，下面是我完整的settings.xml和pom.xml文件，下面是mvn deploy和mvn deploy-e的完整日志。

• 我使用settings.xml中的用户/pass成功地登录和退出了sonatype.org网站。
• 我尝试使用curl手动部署工件，使用命令

[C:\]curl-u my_sonatype_dot_com_username:my_sonatype_dot_com_password https://oss.sonatype.org/content/repositories/snapshots/com/github/aliteralmind/xbnjava/0.1.2-snapshot/xbnjava-0.1.2-20140716.224928-1.pom--request [e-mail]

但出现了以下错误：

Warning: Couldn't read data from file "pom.xml", this makes an empty POST.
curl: (60) SSL certificate problem, verify that the CA cert is OK. Details:
error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed
More details here: http://curl.haxx.se/docs/sslcerts.html

curl performs SSL certificate verification by default, using a "bundle"
 of Certificate Authority (CA) public keys (CA certs). If the default
 bundle file isn't adequate, you can specify an alternate file
 using the --cacert option.
If this HTTPS server uses a certificate signed by a CA represented in
 the bundle, the certificate verification probably failed due to a
 problem with the certificate (it might be expired, or the name might
 not match the domain name in the URL).
If you'd like to turn off curl's verification of the certificate, use
 the -k (or --insecure) option.

我使用-k选项再次运行它，这次只得到了以下结果：

Couldn't read data from file "pom.xml", this makes an empty POST.

我以前从未使用过curl，所以我对如何处理这些信息感到茫然。

核对表项目2。如果没有错误输出，请确保在服务器上正确配置了用户特权。请确保删除您刚刚创建的回购。

null

核对表项目3。确保您已经在settings.xml中配置了服务器，并且服务器id与pom.xml中的分发存储库id相同。

• 在settings.xml中，settings/servers/server/id等于ossrh
• 在pom.xml中，distributionmanagement/snapshotrepository/id等于ossrh

（完整文件在底部）

核对表项目4。确保settings.xml位于正确的位置（通常是_~/.m2/settings.xml）。您可以通过运行mvn help：effective-settings来检查这一点。

根据Maven的settings参考，settings.xml必须位于以下两个位置之一：

• Maven安装:$M2_HOME/conf/settings.xml
• 用户的安装:${user.home}/.m2/settings.xml

null

我不明白它指的是哪个url。

在尝试将Gradle artefact部署到Nexus Sonatype存储库时，我也遇到过类似的错误。如果您提供了错误的凭据（密码等），您将得到一个401未经授权的错误。如果您试图将某个版本发布到版本库中，并且该版本已经存在于该版本库中，那么您还会得到一个错误（我的头上也有一个401错误）。因此，您可能会发现，通过命令行发布，它可以工作，但当您从脚本执行时，它会失败（因为它第一次在存储库中不存在）。或者使用不同的版本号发布，或者删除服务器上的旧人工制品并重新发布。

快照存储库（与发布存储库相反）允许您覆盖编号类似的版本，但您的版本号末尾应该有“-snapshot”。
