求大神指点，高分！EclipseLUNA4.4.2版本安装Spring插件安装不上2017-8-15

Question

我试过了在线安装，离线安装，Eclipse卸载了重装都安不上，要疯了
显示cannot found 什么东西，然后显示只能安装部分，
如果勾选那个在线更新，会等很久，有几次更新到最后时40%左右仍然会出错
安装Spring插件安装出错：
An error occurred while collecting items to be installed session context was:(profile=epp.package.je...

session context was:(profile=epp.package.jee, phase=org.eclipse.equinox.internal.p2.engine.phases.Collect, operand=, action=).

出现错误的原因是Eclipse的更新管理P2出错了。
p2有它的一个垃圾回收机制，之前删除的JAR包在未被回收之前，再次重装，系统不会做重新download的动作，但是它又找不到那个JAR包了，故而报错。
解决办法：
在运行命令行中切换到Eclipse的安装根目录，即eclipse.exe所在目录执行命令:
Eclipse目录下cmd运行
eclipse -application org.eclipse.equinox.p2.garbagecollector.application -profile epp.package.jee

然后我是插件包解压本地使用，但是勾选了选择在线更新，一样的朋友的可以试一下这个方法
