在eclipse装spring tools suite遇到的问题

问题一：
Cannot complete the install because of a conflicting dependency.
Software being installed: Spring IDE AJDT Integration (optional) 3.4.0.201310051539-RELEASE (org.springframework.ide.eclipse.ajdt.feature.feature.group 3.4.0.201310051539-RELEASE)
Software currently installed: EclEmma Java Code Coverage 3.1.2.201903112331 (org.eclipse.eclemma.feature.feature.group 3.1.2.201903112331)
Only one of the following can be installed at once:
Java Development Tools Core 3.9.0.xx-20130828-1400-e43-RELEASE (org.eclipse.jdt.core 3.9.0.xx-20130828-1400-e43-RELEASE)
Java Development Tools Core 3.11.2.v20160128-0629 (org.eclipse.jdt.core 3.11.2.v20160128-0629)
Cannot satisfy dependency:
From: AspectJ Development Tools Core 2.2.4.e43x-20130830-1500 (org.eclipse.ajdt.core 2.2.4.e43x-20130830-1500)
To: bundle org.eclipse.jdt.core [3.9.0,3.9.9)

Cannot satisfy dependency:

To: package org.eclipse.ajdt.core 0.0.0

可能的原因：sts版本不对，必须要和eclipse的版本相匹配
解决方法：到官网找到正确的版本，下载并安装。

1. 打开官网 https://spring.io/tools3/sts/all
   

2. 寻找合适的版本（我的eclipse是Mars4.5.0）（eclipse版本号在打开eclipse->help->about eclipse中查看）
   

3. 右键复制连接地址
   
   得到下面的地址：
   https://download.springsource.com/release/STS/3.7.0.RELEASE/dist/e4.5/spring-tool-suite-3.7.0.RELEASE-e4.5-win32-x86_64.zip

4. 修改得到的地址
   
   新的地址：
   https://download.springsource.com/release/TOOLS/update/3.7.0.RELEASE/e4.5/springsource-tool-suite-3.7.0.RELEASE-e4.5.0-updatesite.zip

5. 把新的地址复制到浏览器，即可下载

问题二：
这个问题是问题一解决之后蹦出来的
Cannot complete the install because one or more required items could not be found.

可能原因一：缺少GEF插件。 解决方法：安装GEF插件（但是大家可以试一试，网上很多搜一下）。是否解决：没有解决

可能原因二：未知。解决方法：安装时勾选联网选项。是否解决：解决了。

因为看很多安装教程都说不要选这个，会很慢，我就没有选。然后我就试了一下勾上会不会成功结果就很神奇的安上了，没有等很久，差不多十分钟左右。

问题三：重启后欢迎界面没有显示Spring IDE，但是preferences里有Spring
我也不知道这到底是安上了还是没安上，也不知道咋解决。先试试能不能用吧。
—————————————————————————————
第二天打开Eclipse的时候欢迎界面又有Spring IDE了，可能第一天软件没有反应过来。所以只要在preferences中能看到Spring就算安装成功了。
