Maven安装第三方Jar包到本地仓库
Maven安装第三方Jar包到本地仓库
译者：logan
尽管很少存在这样的情况，有时在你的构建过程中，需要将第三方jar包添加到本地仓库中，因为它并存在于像Maven中央仓库或其它的公共仓库中。为了让Maven能够正确获取到jar包，第三方jar包必须放置到本地仓库的正确位置上。Maven已经提供了maven-install-plugin这样的插件能够使Jar包的安装过程更加容易、更少出错。可以用下面的命令安装一个JAR包到本地仓库。
mvn install:install-file -Dfile= -DgroupId= -DartifactId= -Dversion= -Dpackaging=
如果也有pom文件的话，你可以使用下面的命令安装：
mvn install:install-file -Dfile= -DpomFile=
maven-install-plugin的2.5版本使安装过程更加好用，如果jar包是通过Maven构建的，它会在目录META-INF的子文件夹下创建一个pom.xml文件，这个Jar包会被默认读取。在这种情况下，你只需要这么做：
mvn install:install-file -Dfile=

先说结果吧，要添加其它的远程仓库，需要在maven的conf目录下的setting.xml里面添加下面配置：
&profiles& 节点下添加（里面的url地址就是仓库的地址，根据自己的情况替换就好了）：
&id&dev&/id&
&repositories&
&repository&
&id&company&/id&
&name&company&/name&
&url&http://192.168.2.202:8081/nexus/content/repositories/releases/&/url&
&releases&
&enabled&true&/enabled&
&/releases&
&snapshots&
&enabled&false&/enabled&
&/snapshots&
&/repository&
&/repositories&
&pluginRepositories&
&pluginRepository&
&id&company&/id&
&name&company&/name&
&url&http://192.168.2.202:8081/nexus/content/repositories/releases/&/url&
&releases&
&enabled&true&/enabled&
&/releases&
&snapshots&
&enabled&false&/enabled&
&/snapshots&
&/pluginRepository&
&/pluginRepositories&
&/profile&
同时在setting.xml最后&/settings&之前加上下面的（这里的dev就是上面repository的id）：
&activeProfiles&
&activeProfile&dev&/activeProfile&
&/activeProfiles&
这样就可以从其它的仓库下载了
从Maven仓库中导出jar包：进入工程pom.xml 所在的目录下，输入：
mvn dependency:copy-dependencies
会导出到targed/dependency 下面
可以在工程创建lib文件夹，输入以下命令：
mvn dependency:copy-dependencies -DoutputDirectory=lib
这样jar包都会copy到工程目录下的lib里面
可以设置依赖级别，通常用编译需要的jar
mvn dependency:copy-dependencies -DoutputDirectory=lib
-DincludeScope=compile
查看一个插件的常用命令描述：
mvn help:describe -Dplugin=插件名字
mvn help:describe -Dplugin=dependency
可以查看dependency插件的常用命令。

创建一个最简单的maven项目：
mvn archetype:generate -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false
-DgroupId=com.tch.test -DartifactId=simpleMavenProject
mvn archetype:generate -DarchetypeGroupId=org.apache.maven.archetypes -DarchetypeArtifactId=maven-archetype-webapp -DgroupId=com.mycompany.app -DartifactId=my-webapp
maven下载依赖jar包的源码和javadoc：
mvn dependency:sources
mvn dependency:resolve -Dclassifier=javadoc
maven多模块示例：
假设在名字为simple-parent的文件夹下面有一个pom.xml （也就是所谓的父模块pom.xml）、一个名字为 firstChild 的文件夹（里面是一个maven子模块）、一个名字为secondChild的文件夹（里面也是一个maven子模块）
其中父模块pom.xml 内容为：
注意：模块的加载顺序和该模块在父模块的pom.xml中配置的顺序有关，例如下面的firstChild就会先于secondChild模块
&project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

在父pom.xml中配置 dependency 和 配置 dependencyManagement 的区别：
在父pom.xml中配置dependency的话，子模块就会继承该依赖，假如父pom.xml中配置了下面的依赖：
&dependency&
&groupId&junit&/groupId&
&artifactId&junit&/artifactId&
&version&3.8.1&/version&
&scope&test&/scope&
&/dependency&
然后在子模块运行下面命令查看子模块的依赖：
mvn dependency:resolve
就会发现子模块的依赖包含了上面再父pom.xml中配置的依赖。类似于java里面继承的效果。
如果在父pom.xml中配置dependencyManagement的话，假如dependencyManagement里面配置了上面同样的依赖：
&dependencyManagement&
&dependencies&
&dependency&
&groupId&junit&/groupId&
&artifactId&junit&/artifactId&
&version&3.8.1&/version&
&scope&test&/scope&
&/dependency&
&/dependencies&
&/dependencyManagement&
然后在子模块运行
mvn dependency:resolve
查看子模块的依赖的话，就会发现子模块并没有继承父模块dependencyManagement里面配置的依赖。
要想使用父模块dependencyManagement里面配置的依赖，需要在子模块配置（注意没有version）：
&dependency&
&groupId&junit&/groupId&
&artifactId&junit&/artifactId&
&/dependency&
，然后在子模块运行
mvn dependency:resolve
命令查看子模块的依赖，就会发现子模块的依赖包含了junit，并且版本号是父pom.xml里面配置的版本号。
所以，dependencyManagement 其实是为了统一管理版本号，把公用的依赖放到dependencyManagement里面管理，在需要引用该依赖的地方只需要groupId和artifactId即可引用该依赖。避免了版本号不同引发的问题
使用jetty插件运行web项目：
在pom.xml 的build 中添加jetty插件：（版本号自定）
&groupId&org.mortbay.jetty&/groupId&
&artifactId&maven-jetty-plugin&/artifactId&
&version&${jetty-version}&/version&
然后运行命令：mvn jetty:run 即可
貌似如果运行tomcat插件的话，我这里直接运行
mvn tomcat:run
就可以了，没有配置tomcat插件。。。
使用Maven CXF插件根据WSDL生成java类：
&groupId&org.apache.cxf&/groupId&
&artifactId&cxf-codegen-plugin&/artifactId&
&version&2.7.8&/version&
&executions&
&execution&
&id&generate-sources&/id&

&/wsdlOption&
&/wsdlOptions&
&/configuration&
&goal&wsdl2java&/goal&
&/execution&
&/executions&
&/plugins&
然后执行 mvn generate-sources 即可在src/cxf目录下生成java类
将项目依赖的jar包的源码下载到目录dependency_src目录，但不解压（以jar格式）：
mvn dependency:copy-dependencies -DoutputDirectory=dependency_src
-DincludeScope=compile -Dclassifier=sources
将项目依赖的jar包的源码下载到目录dependency_src目录并解压：
mvn dependency:unpack-dependencies -Dclassifier=sources -DfailOnMissingClassifierArtifact=false -DoutputDirectory=dependency_src -DincludeScope=compile
使用jacoco生成测试覆盖率report :

多个module的时候，我们修改了某个module，然后只需要从该module开始build即可，这样就不必要build这个module之前的那些module了：()
mvn clean install -rf
module-name
parent pom.xml和child pom.xml:
parent pom.xml：
&module&my-modules/my-module-1&/module&
&/modules&
The value of &module& is the relative path from the com.mycompany.app:my-app:1 to com.mycompany.app:my-module:1's POM(可以在中搜索这句话)
module的值，是从parent的pom.xml到该module的pom.xml的相对路径
child pom.xml：
&groupId&parent-groupId&/groupId&
&artifactId&parent-artifactId&/artifactId&
&version&parent-version&/version&
&relativePath&../../pom.xml&/relativePath&
relativePath的值，是从该module的pom.xml到parent的pom.xml的相对路径

| 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.home}/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/1.0.0"
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"&
&!-- 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:/Program Files/apache-maven-3.3.1/repository&/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&
&!-- 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.
&!-- proxy
| Specification for one proxy, to be used in connecting to the network.

&nonProxyHosts&local.net|&/nonProxyHosts&
&/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.
&!-- 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.
&id&deploymentRepo&/id&
&username&repouser&/username&
&password&repopwd&/password&
&!-- Another sample, using keys to authenticate.
&id&siteServer&/id&
&privateKey&/path/to/private/key&/privateKey&
&passphrase& leave empty if not used.&/passphrase&
&/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.
&!-- 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&

&/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 id's for debug.
| This profile example uses the JDK version to trigger activation, and provides a JDK-specific repo.
&id&jdk-1.4&/id&
&activation&
&jdk&1.4&/jdk&
&/activation&
&repositories&
&repository&
&id&jdk14&/id&
&name&Repository for JDK 1.4 builds&/name&
&url&/maven/jdk14&/url&
&layout&default&/layout&
&snapshotPolicy&always&/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&
&groupId&org.myco.myplugins&/groupId&
&artifactId&myplugin&/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.
&id&env-dev&/id&
&activation&
&property&
&name&target-env&/name&

话说还是maven工程，关于包的导入与本地和远程仓库的问题收藏
最近准备自己建项目，然后用了maven工程，他们说maven工程经常用不需要经常去管理以前用过的包，所以。。。maven工程有个settings.xml文件进行配置远程仓库和本地仓库。像spring框架包人家官网上有给maven的远程仓库配置以及pom.xml中的配置，所以复制过来有网就能直接下载到本地maven仓库中，并且导入到我配置过的工程里。但是像struts2 官网上没有给maven仓库以及配置，所以我就下下来了。但是问题就来了，我不知道我下载下来的那些jar包怎么导入到工程中才能跟从远程仓库中下载的一样，在本地仓库也会有一份，并且能用。如果答案是必须要先配置远程仓库，想知道，怎么通过tomcat配置多端口访问，因为web项目本身需要一个8080端口，而我只有一台电脑，我先让自己的电脑模拟服务器的方式，配置远程仓库，并且远程仓库中的文件的存放有什么要求吗？
