maven----(Eclipse configuration Chapter)

For Maven, at least in the current development of the use is relatively frequent, but in the IDE integration MAVEN environment, today really let me a headache, generated the project on a variety of small red fork, later integrated various tutorials have been completed, so record:

One, download maven, and the configuration of the environment variable will not be repeated, the commonplace problem

Second, the new Maven local repository, you can create a new folder under a disk, for example, I:

Iii. Configuring the Local repository information in Maven Settings.xml

1 < localrepository > G:\MavenFactory</localrepository>

Iv. Eclispe integrated maven, the new version of Eclispe now has its own MAVEN plugin, if not, self-installing MAVEN plugin, and then in Window--preference, find the path of the settings just modified, click Update

Create a new MAVEN project, right-click the new--maven project----Check the box---and then click "Next"

Fill in the relevant information, packaging there I chose "War", and then click Finish Finish, surprise came, after the completion of the report to me a mistake

Workaround:

Then click on "Generate Deployment descriptor Stub", the above error is good, then click on the item---"Properties"

Six, MAVEN support servlet3.1, need to change the following several files:

(1) Modify the Pom.xml file to add support for servlet3.1 and JDK1.8

1   <!--introduction of servlet3.1 -2   <Dependencies> 3     <Dependency>4        <groupId>Javax.servlet</groupId>  5         <Artifactid>Javax.servlet-api</Artifactid>  6         <version>3.1.0</version>  7         <Scope>Provided</Scope>  8     </Dependency> 9     </Dependencies> Ten    <!--introduction of java1.8 support - One    <Build>   A     <Finalname>Com-demoone</Finalname>   -     <Plugins>   -         <plugin>   the             <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>   A         </plugin>   at     </Plugins>   -   </Build> 

(2) Modify the Web. xml file, as shown in the file location:

Change the Web. XML to the following mode: Web-app to the corresponding 3.1, then save

1 <Web-appxmlns= "Http://xmlns.jcp.org/xml/ns/javaee" 2 Xmlns:xsi= "Http://www.w3.org/2001/XMLSchema-instance" 3 xsi:schemalocation= "Http://xmlns.jcp.org/xml/ns/javaee4 http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd "version= "3.1" 5 Metadata-complete= "true"> 6   <Display-name>Com-demoone</Display-name>7   <welcome-file-list>8     <Welcome-file>Index.htm</Welcome-file>9     <Welcome-file>index.jsp</Welcome-file>Ten   </welcome-file-list> One </Web-app>

(3) There is a setting folder in the root directory of the current project, there is a org.eclipse.wst.common.project.facet.core.xml file, after opening, modify

Modify the following two information, then save, the last step, right-click the entire project---"Maven"---"Update Project", you can

Vii. Modify the JDK version information for MAVEN configuration once and for all, add the following to the MAVEN settings.xml file: Then modify the MAVEN configuration in Eclispe, see figure in step four, associate Settings.xml

1 <Profiles>2     < Profile>    3     <ID>jdk-1.8</ID>    4      <activation>    5           <Activebydefault>True</Activebydefault>    6           <JDK>1.8</JDK>    7       </activation>    8     <Properties>    9             <Maven.compiler.source>1.8</Maven.compiler.source>    Ten             <Maven.compiler.target>1.8</Maven.compiler.target>     One             <maven.compiler.compilerVersion>1.8</maven.compiler.compilerVersion>     A     </Properties>     -     </ Profile> -   </Profiles>
