MyEclipse 6.5安装maven插�g

初一七月 — Tue, 05 Nov 2013 08:19:00 GMT

一、卸载原有maven插�g

MyEclipse 6.5集成了Maven插�g�Q�不�q�有不少bug�Q�用�?f��n)惯了m2eclipse�Q�不惛_��q�上面浪�Ҏ(gu��)��间。要安装m2eclipse�Q�需要先把自带的maven插�g卸蝲掉，卸蝲步骤如下�Q?br />1.删除/eclipse/features/com.genuitec.myeclipse.maven_6.5.1.zmyeclipse650200806目录
2.�q�入plugins目录�Q�删除以下目录及(qi��ng)jar�?br />

1 com.genuitec.myeclipse.maven_6.5.1.zmyeclipse650200806
2 org.maven.ide.components.archetype_common_2.0.0.20080331-1600
3 org.maven.ide.components.maven_embedder_2.1.0.20080410-2200
4 org.maven.ide.components.maven_model_edit_1.0.0.20080331-1600
5 org.maven.ide.components.maven_scm_1.0.0.20080410-2200
6 org.maven.ide.components.nexus_indexer_1.0.0.20080331-1600
7 org.maven.ide.components.qname_1.0.0.20080331-1600
8 com.genuitec.eclipse.maven_6.5.1.zmyeclipse650200806.jar
9 org.maven.ide.eclipse.central_0.9.1.zmyeclipse650200806.jar
10 org.maven.ide.eclipse.scm_0.9.2.zmyeclipse650200806.jar
11 org.maven.ide.eclipse_0.9.3.zmyeclipse650200806.jar

二、在�U�安装m2eclipse

1.Help -> Find and Install ->Search for new features to install->New Remote Site

1 name�Q�m2eclipse
2 url�Q�http://m2eclipse.sonatype.org/sites/m2e/0.10.0.20100209-0800/

2.点击Finish�Q�开始自动搜索。这个链接之前是好用的，不过今天再下载��L��提示错误�Q�直接访问也提示内容找不刎ͼ�看来是挪地方了。最后在官网扑ֈ��q�个帖子Where did http://m2eclipse.sonatype.org/sites/m2e go?�Ҏ(gu��)��提示扑ֈ�了最新地址http://repository.sonatype.org/content/sites/forge-sites/m2e/
帖子内容

As of June 2013, that site has been shut down because M2Eclipse was moved to the Eclipse Foundation years ago.

You can access the archived M2Eclipse sites (including 0.12) here:

https://repository.sonatype.org/content/sites/forge-sites/m2e/

For more information on how to access current m2e releases, see http://eclipse.org/m2e/download/.

所以上面的地址变成了这�?br />

1 name:m2eclipse
2 url:http://repository.sonatype.org/content/sites/forge-sites/m2e/0.10.0/S/20100209-0800/

再安装就没有问题了�?br />
3.讄��maven

Window->preferences�Q�搜索maven�Q�User Settings中选择本地maven配置文�g�Q�Update Settings->Apply->OK

三、问�?/h4>重启MyEclipse后，跛_��异常
1 Eclipse is running in a JRE, but a JDK is required
2 Some Maven plugins may not work when importing projects or updating source folders.

具体的解��x��案见�q�个链接http://m.tkk7.com/itvincent/archive/2010/07/25/327101.html

Maven创徏一个web应用

初一七月 — Thu, 27 Jan 2011 12:29:00 GMT

使用Maven创徏一个简单的web应用�Q��用如下命�?br />

mvn archetype:create -DgroupId=com.mycompany.app -DartifactId=my-webapp -DarchetypeArtifactId=maven-archetype-webapp

切换�?span style="color: #000000;">my-webapp目录下，可以扑ֈ��目对象模型pom.xml

其中packaging标签的�?/span>为war�Q�这�U�打包类型配�|�让Maven以war文�g的�Ş式生成一个web应用。一个打包类型�ؓ(f��)war的项目，��会(x��)在target/目录创徏一个war文�g�Q�这个文件的默认名称是content-zh-webapp-0.6-SNAPSHOT.war。对于这个项目，默认的war文�g是target/simple-webapp-1.0-SNAPSHOT.war。在�q�个��目中，我们已经通过在项目的构徏配置中加入fileName元素来定义生成的war文�g的名�U�ͼ��Ҏ(gu��)��q�个讄��Q�package阶段生成的war文�g为target/my-webapp.war。除此以外，�q?span style="color: #000000;">可以看到src/main/webapp下生成了��单的一个index.jsp以及(qi��ng)WEB-INF下的web��目配置文�gweb.xml�?br />
接下来我们打包程序，�q�行如下命��o(h��)

mvn clean package

�?span style="color: #000000;">my-webapp/target目录下，我们看到了生成的my-webapp.war�?/span>

配置Jetty插�g

在编译�ƈ打包了我们的web应用之后�Q�我们想要将它部�|�到一个servlet容器中，然后��试一下由Maven Archetype插�g生成的index.jsp。一般我们发布web�E�序都需要下载Jetty或Tomcat�{�web容器�Q�解压分发包�Q�然后将我们打好的war包拷贝到webapps目录下，然后启动服务器。利用Maven的Jetty插�g可以省去�q�些步骤�Q�在Maven中运行我们的web应用。�ؓ(f��)此，我们需要在��目的pom.xml文�g中配�|�Jetty插�g�Q�配�|�后的pom.xml如下

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

上面的文仉��了jetty外，�q�配�|�了maven-compiler-plugin�~�译插�g�Q�此插�g可以用来指定�~�译器版本，以及(qi��ng)其他一些编译细节�?br />
