问题背景：
???????? 在myeclipse10下用其自带的maven 运行jetty,在开发项目时，每修改一个地方（非接口或方法）都得重新启动项目才能看到修改结果，给开发带来了很大的不便，经网上查询处理办法如下：
?
0、安全考虑，先把代码提交，关掉myeclipse
1、解压jrebel.zip(见附件)到..\MyEclipse\myPlugins
2、cmd打开命令行
3、cd进入..\MyEclipse\myPlugins\jrebel\bin
4、输入activate.cmd ./jrebel.lic? 回车
5、输入activate.cmd ../jrebel.lic 回车
6、cd进入项目根路径
7、输入mvn javarebel:generate 回车
8、输入set MAVEN_OPTS=-noverify -javaagent:D:\MyEclipse\myPlugins\jrebel 回车
9、配置pom.xml ，打开myeclipse
配置中增加：
?<!-- jrebel start-->
?<repositories>?
??????? <repository>?
??????????? <id>zt-repo</id>?
??????????? <url>http://repos.zeroturnaround.com/maven2</url>?
??????? </repository>?
?</repositories>

?<pluginRepositories>?
???????? <pluginRepository>?
???? ?<id>zt-repo</id>?
???? ?<name>Zero turnaround repo</name>?
???? ?<url>http://repos.zeroturnaround.com/maven2</url>?
???????? </pluginRepository>?
?</pluginRepositories>?
<!-- jrebel end-->
插件中增加：
<!-- jrebel start-->
?<plugin>
??<groupId>org.zeroturnaround</groupId>?
??????? <artifactId>javarebel-maven-plugin</artifactId>?
?? ??<version>1.0.5</version>?
??? ?<executions>?
???????? <execution>?
??????????? <id>generate-rebel-xml</id>?
??????????? <phase>process-resources</phase>?
??????????? <goals>?
???????? ??<goal>generate</goal>?
???????? ?</goals>?
???????? </execution>?
??? ?</executions>?
?</plugin>
?<plugin>??

?<!-- jrebel end -->
10、项目跑一下，欧了
