maven插件设置：
1.maven插件：eclipse内置：
2.maven插件设置：
- installations:指定maven核心程序的位置，不建议使用插件自带的maven程序，而应该使用我们自己解压的maven程序；
- user settings:指定conf/settings.xml的位置，进而获取本地仓库的位置；
3.maven解压目录\config\settings.xml：
1 <?xml version="1.0" encoding="UTF-8"?>

23 | This is the configuration file for Maven. It can be specified at two levels:
24 |
25 | 1. User Level. This settings.xml file provides configuration for a single user,
26 | and is normally provided in ${user.home}/.m2/settings.xml.
27 |
28 | NOTE: This location can be overridden with the CLI option:
29 |
30 | -s /path/to/user/settings.xml
31 |
32 | 2. Global Level. This settings.xml file provides configuration for all Maven
33 | users on a machine (assuming they're all using the same Maven
34 | installation). It's normally provided in
35 | ${maven.conf}/settings.xml.
36 |
37 | NOTE: This location can be overridden with the CLI option:
38 |
39 | -gs /path/to/global/settings.xml
40 |
41 | The sections in this sample file are intended to give you a running start at
42 | getting the most out of your Maven installation. Where appropriate, the default
43 | values (values used when the setting is not specified) are provided.
44 |
45 |-->
46 <settings xmlns="http://maven.apache.org/SETTINGS/1.2.0"
47 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
48 xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.2.0 https://maven.apache.org/xsd/settings-1.2.0.xsd">
49 <!-- localRepository
50 | The path to the local repository maven will use to store artifacts.
51 |

53 <localRepository>/path/to/local/repo</localRepository>
54 -->
55 <localRepository>/Users/lixiuming/.m2/repository</localRepository>
56 <!-- interactiveMode
57 | This will determine whether maven prompts you when it needs input. If set to false,
58 | maven will use a sensible default value, perhaps based on some other setting, for
59 | the parameter in question.
60 |
61 | Default: true
62 <interactiveMode>true</interactiveMode>
63 -->
64
65 <!-- offline
66 | Determines whether maven should attempt to connect to the network when executing a build.
67 | This will have an effect on artifact downloads, artifact deployment, and others.
68 |
69 | Default: false
70 <offline>false</offline>
71 -->
72
73 <!-- pluginGroups
74 | This is a list of additional group identifiers that will be searched when resolving plugins by their prefix, i.e.
75 | when invoking a command line like "mvn prefix:goal". Maven will automatically add the group identifiers
76 | "org.apache.maven.plugins" and "org.codehaus.mojo" if these are not already contained in the list.
77 |-->
78 <pluginGroups>
79 <!-- pluginGroup
80 | Specifies a further group identifier to use for plugin lookup.
81 <pluginGroup>com.your.plugins</pluginGroup>
82 -->
83 </pluginGroups>
84
85 <!-- proxies
86 | This is a list of proxies which can be used on this machine to connect to the network.
87 | Unless otherwise specified (by system property or command-line switch), the first proxy
88 | specification in this list marked as active will be used.
89 |-->

105 </proxies>
106
107 <!-- servers
108 | This is a list of authentication profiles, keyed by the server-id used within the system.
109 | Authentication profiles can be used whenever maven must make a connection to a remote server.
110 |-->
111 <servers>
112 <!-- server
113 | Specifies the authentication information to use when connecting to a particular server, identified by
114 | a unique name within the system (referred to by the 'id' attribute below).
115 |
116 | NOTE: You should either specify username/password OR privateKey/passphrase, since these pairings are
117 | used together.
118 |
119 <server>
120 <id>deploymentRepo</id>
121 <username>repouser</username>

130 <passphrase>optional; leave empty if not used.</passphrase>
131 </server>
132 -->
133 </servers>
134
135 <!-- mirrors
136 | This is a list of mirrors to be used in downloading artifacts from remote repositories.
137 |
138 | It works like this: a POM may declare a repository to use in resolving certain artifacts.
139 | However, this repository may have problems with heavy traffic at times, so people have mirrored
140 | it to several places.
141 |
142 | That repository definition will have a unique id, so we can create a mirror reference for that
143 | repository, to be used as an alternate download site. The mirror site will be the preferred
144 | server for that repository.
145 |-->
146 <mirrors>
147 <!-- mirror
148 | Specifies a repository mirror site to use instead of a given repository. The repository that
149 | this mirror serves has an ID that matches the mirrorOf element of this mirror. IDs are used
150 | for inheritance and direct lookup purposes, and must be unique across the set of mirrors.
151 |
152 <mirror>
153 <id>mirrorId</id>
154 <mirrorOf>repositoryId</mirrorOf>
155 <name>Human Readable Name for this Mirror.</name>
156 <url>http://my.repository.com/repo/path</url>
157 </mirror>
158 -->
159 <mirror>
160 <id>maven-default-http-blocker</id>
161 <mirrorOf>external:http:*</mirrorOf>
162 <name>Pseudo repository to mirror external repositories initially using HTTP.</name>
163 <url>http://0.0.0.0/</url>
164 <blocked>true</blocked>
165 </mirror>
166 </mirrors>
167
168 <!-- profiles
169 | This is a list of profiles which can be activated in a variety of ways, and which can modify
170 | the build process. Profiles provided in the settings.xml are intended to provide local machine-
171 | specific paths and repository locations which allow the build to work in the local environment.
172 |
173 | For example, if you have an integration testing plugin - like cactus - that needs to know where
174 | your Tomcat instance is installed, you can provide a variable here such that the variable is
175 | dereferenced during the build process to configure the cactus plugin.
176 |
177 | As noted above, profiles can be activated in a variety of ways. One way - the activeProfiles
178 | section of this document (settings.xml) - will be discussed later. Another way essentially
179 | relies on the detection of a system property, either matching a particular value for the property,
180 | or merely testing its existence. Profiles can also be activated by JDK version prefix, where a
181 | value of '1.4' might activate a profile when the build is executed on a JDK version of '1.4.2_07'.
182 | Finally, the list of active profiles can be specified directly from the command line.
183 |
184 | NOTE: For profiles defined in the settings.xml, you are restricted to specifying only artifact
185 | repositories, plugin repositories, and free-form properties to be used as configuration
186 | variables for plugins in the POM.
187 |
188 |-->
189 <profiles>
190 <!-- profile
191 | Specifies a set of introductions to the build process, to be activated using one or more of the
192 | mechanisms described above. For inheritance purposes, and to activate profiles via <activatedProfiles/>
193 | or the command line, profiles have to have an ID that is unique.
194 |
195 | An encouraged best practice for profile identification is to use a consistent naming convention
196 | for profiles, such as 'env-dev', 'env-test', 'env-production', 'user-jdcasey', 'user-brett', etc.
197 | This will make it more intuitive to understand what the set of introduced profiles is attempting
198 | to accomplish, particularly when you only have a list of profile id's for debug.
199 |
200 | This profile example uses the JDK version to trigger activation, and provides a JDK-specific repo.
201 <profile>
202 <id>jdk-1.4</id>
203
204 <activation>
205 <jdk>1.4</jdk>
206 </activation>
207
208 <repositories>
209 <repository>
210 <id>jdk14</id>
211 <name>Repository for JDK 1.4 builds</name>
212 <url>http://www.myhost.com/maven/jdk14</url>
213 <layout>default</layout>
214 <snapshotPolicy>always</snapshotPolicy>
215 </repository>
216 </repositories>
217 </profile>
218 -->
219
220 <!--
221 | Here is another profile, activated by the system property 'target-env' with a value of 'dev',
222 | which provides a specific path to the Tomcat instance. To use this, your plugin configuration
223 | might hypothetically look like:
224 |
225 | ...
226 | <plugin>
227 | <groupId>org.myco.myplugins</groupId>
228 | <artifactId>myplugin</artifactId>
229 |
230 | <configuration>
231 | <tomcatLocation>${tomcatPath}</tomcatLocation>
232 | </configuration>
233 | </plugin>
234 | ...
235 |
236 | NOTE: If you just wanted to inject this configuration whenever someone set 'target-env' to
237 | anything, you could just leave off the <value/> inside the activation-property.
238 |
239 <profile>
240 <id>env-dev</id>
241
242 <activation>
243 <property>
244 <name>target-env</name>

创建maven版java工程
创建maven工程--选择简单的工程--选择创建位置(/或者就是勾选住 user default workspace location)
填写对应的坐标信息和 packaging 为jar，
jre 环境：
默认jdk1.5;修改环境
如果想要默认加入的maven项目就是jdk1.8,就需要在setting.xml中找到profiles标签加入即可；
<profile>
<id>jdk-1.8</id>
<activation>
<activeByDefault>true</activeByDefault>
<jdk>1.8</jdk>
</activation>
<properties>
<maven.compiler.source>1.8</maven.compiler.source>
<maven.compiler.target>1.8</maven.compiler.target>
<maven.compiler.compilerVersion>1.8</maven.compiler.compilerVersion>
</properties>
</profile> 或者在pom.xml中加入
<build>
<pluginManagement>
<plugins>
<!-- maven jdk version -->
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.1</version>
<configuration>
<source>1.8</source>
<target>1.8</target>
</configuration>
</plugin>
</pluginManagement>
</build> 执行maven命令：
pom.xml右键 执行对应的 maven命令即可；
如果需要执行cmpile,在build...中，添加goles：为compile ,run 即可；
创建maven版web工程
和创建java工程类似，唯一的区别是packaging 不是jar，是war；
项目配置：
默认创建的项目 没有web.xml ,没有web-info 等，需要配置；右键项目名称；选择project Facets 选择Dynamic Web Module 直到下面出现furter configuration avi...,(如果不出现，反复勾选几次)点击他配置web目录和web.xml;
web工程的自动部署配置：
