三 maven 私服配置说明
总结

前言

maven仓库的私服,一般会存放公司或者个人封装的jar包,用来共享给二次开发和协作伙伴用,很方便

第一次发布没有问题,但是我第二次发布,开始报错了

一、直接看报错

[外链图片转存失败,源站可能有防盗链机制,建议将图片保存下来直接上传(img-BGqiXGIe-1721546348045)(https://i-blog.csdnimg.cn/direct/b15cc2dd57d54870849827891438d7c4.png)]

401 无权限
我这个是400 说明用户名密码是对的

二、问题处理

其实很简单,这个错误是因为我没有开启,已经存在的jar 可以覆盖推送

登录私服用户名密码
选择左侧 Repositories
选中要推送的仓库地址的 Repositories
修改Configuration配置 Deployment Policy 默认为 Disable Redeploy 改为 Allow Redeploy

三 maven 私服配置说明

有了maven私服,先配置自己maven的setting文件

--><!--| This is the configuration file for Maven. It can be specified at two levels:||  1. User Level. This settings.xml file provides configuration for a single user,|                 and is normally provided in ${user.home}/.m2/settings.xml.||                 NOTE: This location can be overridden with the CLI option:||                 -s /path/to/user/settings.xml||  2. Global Level. This settings.xml file provides configuration for all Maven|                 users on a machine (assuming they're all using the same Maven|                 installation). It's normally provided in|                 ${maven.conf}/settings.xml.||                 NOTE: This location can be overridden with the CLI option:||                 -gs /path/to/global/settings.xml|| The sections in this sample file are intended to give you a running start at| getting the most out of your Maven installation. Where appropriate, the default| values (values used when the setting is not specified) are provided.||-->
<settings xmlns="http://maven.apache.org/SETTINGS/1.2.0"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.2.0 https://maven.apache.org/xsd/settings-1.2.0.xsd"><!-- localRepository| The path to the local repository maven will use to store artifacts.|| Default: ${user.home}/.m2/repository<localRepository>/path/to/local/repo</localRepository>-->
<localRepository>D:\JAVA\apache-maven-3.9.3\repo</localRepository><!-- interactiveMode| This will determine whether maven prompts you when it needs input. If set to false,| maven will use a sensible default value, perhaps based on some other setting, for| the parameter in question.|| Default: true<interactiveMode>true</interactiveMode>--><!-- offline| Determines whether maven should attempt to connect to the network when executing a build.| This will have an effect on artifact downloads, artifact deployment, and others.|| Default: false<offline>false</offline>--><!-- pluginGroups| This is a list of additional group identifiers that will be searched when resolving plugins by their prefix, i.e.| when invoking a command line like "mvn prefix:goal". Maven will automatically add the group identifiers| "org.apache.maven.plugins" and "org.codehaus.mojo" if these are not already contained in the list.|--><pluginGroups><!-- pluginGroup| Specifies a further group identifier to use for plugin lookup.<pluginGroup>com.your.plugins</pluginGroup>--></pluginGroups><!-- TODO Since when can proxies be selected as depicted? --><!-- proxies| This is a list of proxies which can be used on this machine to connect to the network.| Unless otherwise specified (by system property or command-line switch), the first proxy| specification in this list marked as active will be used.|--><proxies><!-- proxy| Specification for one proxy, to be used in connecting to the network.|<proxy><id>optional</id><active>true</active><protocol>http</protocol><username>proxyuser</username><password>proxypass</password><host>proxy.host.net</host><port>80</port><nonProxyHosts>local.net|some.host.com</nonProxyHosts></proxy>--></proxies><!-- servers| This is a list of authentication profiles, keyed by the server-id used within the system.| Authentication profiles can be used whenever maven must make a connection to a remote server.|--><servers><!-- server| Specifies the authentication information to use when connecting to a particular server, identified by| a unique name within the system (referred to by the 'id' attribute below).|| NOTE: You should either specify username/password OR privateKey/passphrase, since these pairings are|       used together.|<server><id>deploymentRepo</id><username>repouser</username><password>repopwd</password></server>--><!-- Another sample, using keys to authenticate.<server><id>siteServer</id><privateKey>/path/to/private/key</privateKey><passphrase>optional; leave empty if not used.</passphrase></server>--><server><id>activeId</id><username>用户名</username><password>密码</password></server><server><id>Releases</id><username>用户名</username><password>密码</password></server><server><id>Snapshots</id><username>用户名</username><password>密码</password></server></servers><!-- mirrors| This is a list of mirrors to be used in downloading artifacts from remote repositories.|| It works like this: a POM may declare a repository to use in resolving certain artifacts.| However, this repository may have problems with heavy traffic at times, so people have mirrored| it to several places.|| That repository definition will have a unique id, so we can create a mirror reference for that| repository, to be used as an alternate download site. The mirror site will be the preferred| server for that repository.|--><mirrors><!-- mirror| Specifies a repository mirror site to use instead of a given repository. The repository that| this mirror serves has an ID that matches the mirrorOf element of this mirror. IDs are used| for inheritance and direct lookup purposes, and must be unique across the set of mirrors.|<mirror><id>mirrorId</id><mirrorOf>repositoryId</mirrorOf><name>Human Readable Name for this Mirror.</name><url>http://my.repository.com/repo/path</url></mirror><mirror><mirrorOf>local</mirrorOf><name>localmaven</name><id>thirdparty</id><url>http://192.168.1.115:8081/nexus/content/repositories/thirdparty/</url></mirror>--><mirror><id>alimaven</id><name>aliyun maven</name><url>http://maven.aliyun.com/nexus/content/groups/public/</url><mirrorOf>central</mirrorOf></mirror><mirror><id>alimaven</id><mirrorOf>central</mirrorOf><name>aliyun maven</name><url>http://maven.aliyun.com/nexus/content/repositories/central/</url></mirror></mirrors><!-- profiles| This is a list of profiles which can be activated in a variety of ways, and which can modify| the build process. Profiles provided in the settings.xml are intended to provide local machine-| specific paths and repository locations which allow the build to work in the local environment.|| For example, if you have an integration testing plugin - like cactus - that needs to know where| your Tomcat instance is installed, you can provide a variable here such that the variable is| dereferenced during the build process to configure the cactus plugin.|| As noted above, profiles can be activated in a variety of ways. One way - the activeProfiles| section of this document (settings.xml) - will be discussed later. Another way essentially| relies on the detection of a property, either matching a particular value for the property,| or merely testing its existence. Profiles can also be activated by JDK version prefix, where a| value of '1.4' might activate a profile when the build is executed on a JDK version of '1.4.2_07'.| Finally, the list of active profiles can be specified directly from the command line.|| NOTE: For profiles defined in the settings.xml, you are restricted to specifying only artifact|       repositories, plugin repositories, and free-form properties to be used as configuration|       variables for plugins in the POM.||--><profiles><profile><id>activeId</id><repositories><repository><id>central</id><name>MyRepository</name><url>http://ip:端口/nexus/content/repositories</url><releases><enabled>true</enabled></releases><snapshots><enabled>true</enabled></snapshots></repository><repository><id>thirdparty</id><url>http://ip:端口/nexus/content/repositories/thirdparty/</url></repository></repositories><pluginRepositories><pluginRepository><id>central</id><url>http://ip:端口/nexus/content/repositories</url><releases><enabled>true</enabled></releases><snapshots><enabled>true</enabled></snapshots></pluginRepository></pluginRepositories></profile></profiles><!-- activeProfiles| List of profiles that are active for all builds.|<activeProfiles><activeProfile>alwaysActiveProfile</activeProfile><activeProfile>anotherAlwaysActiveProfile</activeProfile></activeProfiles>--><activeProfiles><activeProfile>activeId</activeProfile></activeProfiles>

要推送jar ,应该在项目的pom中配置私服地址
