MyEclipse部署工程到Tomcat失败的一种情况及解决

cl_303303303

  本来好好的MyEclipse6.0被我删除后重新安装了6.5版本后，又重新安装了subclipse和m2eclipse等插件，启动后，都还不错。就是在原来的workspace中的web项目部署的时候问题出来了，部署到最后出现了错误:
An internal error occurred during: "Redeploy".

maven里的jar包都没有部署到tomcat的lib里。
网上查了一圈，有说换换workspace的，也由其它问题。
看了日志应该和maven有关系，终于搜到一位说明的问题原因解决方法。原来MyEclipse6.5自带了一个Maven客户端插件--maven4myeclipse，它和m2eclipse是会发生冲突的先要删除这个自带的插件，m2eclipse才能正常工作。
 
于是照着做：
手动来了
关闭Eclipse程序, 进入MyEclipse插件目录/eclipse/features,/myeclipse/features
删除com.genuitec.myeclipse.maven_6.5.1.zmyeclipse650200806目录,
接着删除plugins目录下的com.genuitec.myeclipse.maven_6.5.1.zmyeclipse650200806, org.maven.ide.components.archetype_common_2.0.0.20080331-1600, org.maven.ide.components.maven_embedder_2.1.0.20080410-2200, org.maven.ide.components.maven_model_edit_1.0.0.20080331-1600(?org.maven.ide.components.maven_model_edit_1.0.0.20080905-0917.jar), org.maven.ide.components.maven_scm_1.0.0.20080410-2200,
org.maven.ide.components.nexus_indexer_1.0.0.20080331-1600,
org.maven.ide.components.qname_1.0.0.20080331-1600目录,
还有com.genuitec.eclipse.maven_6.5.1.zmyeclipse650200806.jar,
org.maven.ide.eclipse.central_0.9.1.zmyeclipse650200806.jar,
org.maven.ide.eclipse.scm_0.9.2.zmyeclipse650200806.jar,
org.maven.ide.eclipse_0.9.3.zmyeclipse650200806.jar
这四个文件. 然后加上-clean参数启动Eclipse,
[ D:\Program Files\MyEclipse 6.5\eclipse\eclipse.exe -vm "C:\jdk1.6.0_06\bin\javaw.exe" -clean ] 
 
果然卸载了启动后，部署正常了不再报错了!!
