一、卸載原有maven插件
MyEclipse 6.5集成了Maven插件，不過(guò)有不少bug，用習(xí)慣了m2eclipse，不想在這上面浪費(fèi)時(shí)間。要安裝m2eclipse，需要先把自帶的maven插件卸載掉，卸載步驟如下：
1.刪除/eclipse/features/com.genuitec.myeclipse.maven_6.5.1.zmyeclipse650200806目錄
2.進(jìn)入plugins目錄，刪除以下目錄及jar包
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、在線安裝m2eclipse
1.Help -> Find and Install ->Search for new features to install->New Remote Site
1 name：m2eclipse
2 url：http://m2eclipse.sonatype.org/sites/m2e/0.10.0.20100209-0800/
2.點(diǎn)擊Finish，開(kāi)始自動(dòng)搜索。這個(gè)鏈接之前是好用的，不過(guò)今天再下載總是提示錯(cuò)誤，直接訪問(wèn)也提示內(nèi)容找不到，看來(lái)是挪地方了。最后在官網(wǎng)找到這個(gè)帖子
Where did http://m2eclipse.sonatype.org/sites/m2e go?根據(jù)提示找到了最新地址
http://repository.sonatype.org/content/sites/forge-sites/m2e/帖子內(nèi)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/.
所以上面的地址變成了這樣
1 name:m2eclipse
2 url:http://repository.sonatype.org/content/sites/forge-sites/m2e/0.10.0/S/20100209-0800/
再安裝就沒(méi)有問(wèn)題了。
3.設(shè)置maven
Window->preferences，搜索maven，User Settings中選擇本地maven配置文件，Update Settings->Apply->OK
三、問(wèn)題
重啟MyEclipse后，跳出異常
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.
