4、配置mvn的xml 注意 1、该文件在开发环境不变的情况下不建议每个项目一个而是多个项目使用一个 2、下载文件较多占用的磁盘比较大 配置步骤 1、新建settings.xml内容如下 需要需改文件中的存储路径《E:\javaProject\repos》根据个人需要修改 ?xml version1.0 encodingUTF-8?!-- Licensed to the Apache Software Foundation (ASF) under one or more contributor license agreements.

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 theyre all using the same Maven | installation). Its 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. | | --

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. pluginGroupcom.your.plugins/pluginGroup --/pluginGroups!-- 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 idoptional/id activetrue/active protocolhttp/protocol usernameproxyuser/username passwordproxypass/password hostproxy.host.net/host port80/port nonProxyHostslocal.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 iddeploymentRepo/id usernamerepouser/username passwordrepopwd/password /server --!-- Another sample, using keys to authenticate. server idsiteServer/id privateKey/path/to/private/key/privateKey passphraseoptional; leave empty if not used./passphrase /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 idmirrorId/id mirrorOfrepositoryId/mirrorOf nameHuman Readable Name for this Mirror./name urlhttp://my.repository.com/repo/path/url /mirror --mirroridnexus-aliyun/idnamenexus-aliyun/nameurlhttps://maven.aliyun.com/repository/public/urlmirrorOfcentral/mirrorOf/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 system 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 | Specifies a set of introductions to the build process, to be activated using one or more of the | mechanisms described above. For inheritance purposes, and to activate profiles via activatedProfiles/ | or the command line, profiles have to have an ID that is unique. | | An encouraged best practice for profile identification is to use a consistent naming convention | for profiles, such as env-dev, env-test, env-production, user-jdcasey, user-brett, etc. | This will make it more intuitive to understand what the set of introduced profiles is attempting | to accomplish, particularly when you only have a list of profile ids for debug. | | This profile example uses the JDK version to trigger activation, and provides a JDK-specific repo. profile idjdk-1.4/id activation jdk1.4/jdk /activation repositories repository idjdk14/id nameRepository for JDK 1.4 builds/name urlhttp://www.myhost.com/maven/jdk14/url layoutdefault/layout snapshotPolicyalways/snapshotPolicy /repository /repositories /profile --!-- | Here is another profile, activated by the system property target-env with a value of dev, | which provides a specific path to the Tomcat instance. To use this, your plugin configuration | might hypothetically look like: | | ... | plugin | groupIdorg.myco.myplugins/groupId | artifactIdmyplugin/artifactId | | configuration | tomcatLocation${tomcatPath}/tomcatLocation | /configuration | /plugin | ... | | NOTE: If you just wanted to inject this configuration whenever someone set target-env to | anything, you could just leave off the value/ inside the activation-property. | profile idenv-dev/id activation property nametarget-env/name valuedev/value /property /activation properties tomcatPath/path/to/tomcat/instance/tomcatPath /properties /profile --/profiles!-- activeProfiles | List of profiles that are active for all builds. | activeProfiles activeProfilealwaysActiveProfile/activeProfile activeProfileanotherAlwaysActiveProfile/activeProfile /activeProfiles --
