先安装jdk，安装tomcat,再安装svn,最后安装IDEA
新建环境变量JAVA_HOME：

C:Program FilesJetBrainsIntelliJ IDEA 2019.1.2pluginsmavenlibmaven3in
报错 intellij idea can't use subversion command line svn
解决： 安装TortoiseSVN ,时一定要勾选command line client tools
idea 获取最新代码时 svn报 E170013
svn: E170013: Commit failed (details follow): svn: E170013: Unable to connect to a repository at URL '' svn: E230001: Server SSL certificate verification failed: certificate issued for a different hostname
解决方法：
file-->settings...-->subversion--->Enable interactive mode 勾选上即可
再获取代码时，会弹出提示框，选Accept,再输入svn账号与密码即可
