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>D:/Program files/apache-maven-3.1.0/repository</localRepository> <!-- localRepository | The path to the local repository maven will use to store artifacts. | | Default: ${user.home}/.m2/repository <localRepository>/path/to/local/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> <!-- 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> <id>remoteRepository</id> <username>lubandev</username> <password>123</password> </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. | <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> --> </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> --> </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> <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> <repository> <id>JBoss_repository</id> <name>company</name> <url>http://repository.jboss.org/nexus/content/groups/public/</url> </repository> <repository> <id>java.net</id> <name>company</name> <url>https://maven.java.net/content/repositories/public/</url> </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> <pluginRepository> <id>JBoss_repository</id> <name>company</name> <url>http://repository.jboss.org/nexus/content/groups/public/</url> </pluginRepository> <pluginRepository> <id>java.net</id> <name>company</name> <url>https://maven.java.net/content/repositories/public/</url> </pluginRepository> </pluginRepositories> </profile> <!-- 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. <profile> <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>http://www.myhost.com/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. | <profile> <id>env-dev</id> <activation> <property> <name>target-env</name> <value>dev</value> </property> </activation> <properties> <tomcatPath>/path/to/tomcat/instance</tomcatPath> </properties> </profile> --> <!-- 设置项目编译的jdk版本 --> <profile> <id>jdk-1.6</id> <activation> <activeByDefault>true</activeByDefault> <jdk>1.6</jdk> </activation> <properties> <maven.compiler.source>1.6</maven.compiler.source> <maven.compiler.target>1.6</maven.compiler.target> <maven.compiler.compilerVersion>1.6</maven.compiler.compilerVersion> </properties> </profile> </profiles> <!-- activeProfiles | List of profiles that are active for all builds. | <activeProfiles> <activeProfile>alwaysActiveProfile</activeProfile> <activeProfile>anotherAlwaysActiveProfile</activeProfile> </activeProfiles> --> <activeProfiles> <activeProfile>dev</activeProfile> </activeProfiles> </settings>
常用Maven插件介绍
我们都知道Maven本质上是一个插件框架,它的核心并不执行任何具体的构建任务,所有这些任务都交给插件来完成,例如编译源代码是由maven-compiler-plugin完成的。进一步说,每个任务对应了一个插件目标(goal),每个插件会有一个或者多个目标,例如maven-compiler-plugin的compile目标用来编译位于src/main/java/
目录下的主源码,testCompile目标用来编译位于src/test/java/
目录下的测试源码。
用户可以通过两种方式调用Maven插件目标。第一种方式是将插件目标与生命周期阶段(lifecycle phase)绑定,这样用户在命令行只是输入生命周期阶段而已,例如Maven默认将maven-compiler-plugin的compile目标与compile生命周期阶段绑定,因此命令mvn compile实际上是先定位到compile这一生命周期阶段,然后再根据绑定关系调用maven-compiler-plugin的compile目标。第二种方式是直接在命令行指定要执行的插件目标,例如mvn archetype:generate 就表示调用maven-archetype-plugin的generate目标,这种带冒号的调用方式与生命周期无关。
认识上述Maven插件的基本概念能帮助你理解Maven的工作机制,不过要想更高效率地使用Maven,了解一些常用的插件还是很有必要的,这可以帮助你避免一不小心重新发明轮子。多年来Maven社区积累了大量的经验,并随之形成了一个成熟的插件生态圈。Maven官方有两个插件列表,第一个列表的GroupId为org.apache.maven.plugins,这里的插件最为成熟,具体地址为:http://maven.apache.org/plugins/index.html。第二个列表的GroupId为org.codehaus.mojo,这里的插件没有那么核心,但也有不少十分有用,其地址为:http://mojo.codehaus.org/plugins.html。
接下来笔者根据自己的经验介绍一些最常用的Maven插件,在不同的环境下它们各自都有其出色的表现,熟练地使用它们能让你的日常构建工作事半功倍。
maven-antrun-plugin
http://maven.apache.org/plugins/maven-antrun-plugin/
maven-antrun-plugin能让用户在Maven项目中运行Ant任务。用户可以直接在该插件的配置以Ant的方式编写Target,然后交给该插件的run目标去执行。在一些由Ant往Maven迁移的项目中,该插件尤其有用。此外当你发现需要编写一些自定义程度很高的任务,同时又觉得Maven不够灵活时,也可以以Ant的方式实现之。maven-antrun-plugin的run目标通常与生命周期绑定运行。
maven-archetype-plugin
http://maven.apache.org/archetype/maven-archetype-plugin/
Archtype指项目的骨架,Maven初学者最开始执行的Maven命令可能就是mvn archetype:generate,这实际上就是让maven-archetype-plugin生成一个很简单的项目骨架,帮助开发者快速上手。可能也有人看到一些文档写了mvn archetype:create,但实际上create目标已经被弃用了,取而代之的是generate目标,该目标使用交互式的方式提示用户输入必要的信息以创建项目,体验更好。maven-archetype-plugin还有一些其他目标帮助用户自己定义项目原型,例如你由一个产品需要交付给很多客户进行二次开发,你就可以为他们提供一个Archtype,帮助他们快速上手。
maven-assembly-plugin
http://maven.apache.org/plugins/maven-assembly-plugin/
maven-assembly-plugin的用途是制作项目分发包,该分发包可能包含了项目的可执行文件、源代码、readme、平台脚本等等。maven-assembly-plugin支持各种主流的格式如zip、tar.gz、jar和war等,具体打包哪些文件是高度可控的,例如用户可以按文件级别的粒度、文件集级别的粒度、模块级别的粒度、以及依赖级别的粒度控制打包,此外,包含和排除配置也是支持的。maven-assembly-plugin要求用户使用一个名为assembly.xml
的元数据文件来表述打包,它的single目标可以直接在命令行调用,也可以被绑定至生命周期。
maven-dependency-plugin
http://maven.apache.org/plugins/maven-dependency-plugin/
maven-dependency-plugin最大的用途是帮助分析项目依赖,dependency:list能够列出项目最终解析到的依赖列表,dependency:tree能进一步的描绘项目依赖树,dependency:analyze可以告诉你项目依赖潜在的问题,如果你有直接使用到的却未声明的依赖,该目标就会发出警告。maven-dependency-plugin还有很多目标帮助你操作依赖文件,例如dependency:copy-dependencies能将项目依赖从本地Maven仓库复制到某个特定的文件夹下面。
maven-enforcer-plugin
http://maven.apache.org/plugins/maven-enforcer-plugin/
在一个稍大一点的组织或团队中,你无法保证所有成员都熟悉Maven,那他们做一些比较愚蠢的事情就会变得很正常,例如给项目引入了外部的SNAPSHOT依赖而导致构建不稳定,使用了一个与大家不一致的Maven版本而经常抱怨构建出现诡异问题。maven-enforcer-plugin能够帮助你避免之类问题,它允许你创建一系列规则强制大家遵守,包括设定Java版本、设定Maven版本、禁止某些依赖、禁止SNAPSHOT依赖。只要在一个父POM配置规则,然后让大家继承,当规则遭到破坏的时候,Maven就会报错。除了标准的规则之外,你还可以扩展该插件,编写自己的规则。maven-enforcer-plugin的enforce目标负责检查规则,它默认绑定到生命周期的validate阶段。
maven-help-plugin
http://maven.apache.org/plugins/maven-help-plugin/
maven-help-plugin是一个小巧的辅助工具,最简单的help:system可以打印所有可用的环境变量和Java系统属性。help:effective-pom和help:effective-settings最为有用,它们分别打印项目的有效POM和有效settings,有效POM是指合并了所有父POM(包括Super POM)后的XML,当你不确定POM的某些信息从何而来时,就可以查看有效POM。有效settings同理,特别是当你发现自己配置的settings.xml没有生效时,就可以用help:effective-settings来验证。此外,maven-help-plugin的describe目标可以帮助你描述任何一个Maven插件的信息,还有all-profiles目标和active-profiles目标帮助查看项目的Profile。
maven-release-plugin
http://maven.apache.org/plugins/maven-release-plugin/
maven-release-plugin的用途是帮助自动化项目版本发布,它依赖于POM中的SCM信息。release:prepare用来准备版本发布,具体的工作包括检查是否有未提交代码、检查是否有SNAPSHOT依赖、升级项目的SNAPSHOT版本至RELEASE版本、为项目打标签等等。release:perform则是签出标签中的RELEASE源码,构建并发布。版本发布是非常琐碎的工作,它涉及了各种检查,而且由于该工作仅仅是偶尔需要,因此手动操作很容易遗漏一些细节,maven-release-plugin让该工作变得非常快速简便,不易出错。maven-release-plugin的各种目标通常直接在命令行调用,因为版本发布显然不是日常构建生命周期的一部分。
