MyEclipse 6.5安装maven插件

一、卸载原有maven插件

MyEclipse 6.5集成了Maven插件，不过有不少bug，用习惯了m2eclipse，不想在这上面浪费时间。要安装m2eclipse，需要先把自带的maven插件卸载掉，卸载步骤如下：
1.删除/eclipse/features/com.genuitec.myeclipse.maven_6.5.1.zmyeclipse650200806目录
2.进入plugins目录，删除以下目录及jar包

二、在线安装m2eclipse

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

2.点击Finish，开始自动搜索。这个链接之前是好用的，不过今天再下载总是提示错误，直接访问也提示内容找不到，看来是挪地方了。最后在官网找到这个帖子Where did http://m2eclipse.sonatype.org/sites/m2e go?根据提示找到了最新地址http://repository.sonatype.org/content/sites/forge-sites/m2e/
帖子内容

所以上面的地址变成了这样

再安装就没有问题了。

3.设置maven

三、问题

重启MyEclipse后，跳出异常

具体的解决方案见这个链接http://www.blogjava.net/itvincent/archive/2010/07/25/327101.html

安装Maven后提示找不到JDK的错误 。The Maven Integration requires that Eclipse be running in a JDK

在eclipse中安装了m2eclipse（maven插件）

在安装后，出现下列警告：

The Maven Integration requires that Eclipse be running in a JDK, because a number of Maven core plugins are using jars from the JDK.

Please make sure the -vm option in eclipse.ini is pointing to a JDK and verify that Installed JRE’s are also using JDK installs.

解决：

（1）设置系统安装的JDK目录set your JDK as a default Java environment in eclipse (default installed JRE)

Open eclipse. Click on ‘Window’ -> ‘Preferences’ -> ‘Java’ -> ‘Installed JREs’.

If you can’t find any JDK on the list -> click ‘Add’ -> ‘Standard VM’ -> set all paths and click ‘Finish’.

After that – check this JDK on the list of installed JREs and click ‘OK’.

（2）增加JDK路径到eclipse.ini文件中add path to your SDK in eclipse.ini

open ‘eclipse.ini’ and add there: -vm path_to_javaw_on_your_machine，so in my example it will be (jdk1.6.0_17 on Windows):-vm
D:\\Java\jdk1.6.0_13\jre\bin\javaw
不能有空格，否则要用~1代替，如： ‘Program Files’ is ‘Progra~1′. Notice 1: Do not use paths with spaces! Replace all dir names with spaces to their shortcuts. For example: ‘Program Files’ is ‘Progra~1′.
要分为2行写。Notice 2: ‘-vm’ is in the first line, path is in the second line

your ‘eclipse.ini’ looks like this:

-startup
plugins/org.eclipse.equinox.launcher_1.0.201.R35x_v20090715.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_1.0.200.v20090519
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
256m
-vm
D:\Java\jdk1.6.0_13\jre\bin\javaw
-vmargs
-Xms40m
-Xmx256m
-vm要在-vmargs前面。Notice : ‘-vm’ must be  "-vmargs" above

重启eclipse。Restart eclipse and everything should be fine.
