Question

按照setting_up_environment'IntelliJ Platform SDK DevGuide'和checkout_and_build_community中的说明进行操作：

安装了IDE
已安装JDK 8
从GIT
按照这两页中的其他说明进行操作

以上所有内容在Ubuntu 15和Windows 8.1 vm上完成了两次。当我尝试构建项目时，我收到了许多关于弃用类和两个错误的警告：

  symbol:   class PathInfo

我已经google了，但未能找到与PathInfo，builtInWebServer或WebServerRootsProvider相关的任何内容。可能是因为谷歌自动假设我的意思是“路径信息”并默默地混合这些结果。

我怀疑这可能是我没有用IDEA下载的东西，比如J2EE或者一些Apache库，但几个小时之后，我已经准备好放弃并问。

回答答案时的一些评论：

在项目中安装并配置Java。如果Java完全缺失，它可能不会抱怨弃用
SDK被定义为'IDEA jdk'，因此它将按照说明

Answer 1

IDEA SDK部分用Kotlin编写，Kotlin是一种在Java虚拟机上运行的静态类型编程语言。

缺少的PathInfo类在PathInfo.kt中定义，即Kotlin文件。

选择文件|设置|插件并单击“安装JetBrains插件”。选择Kotlin插件，错误就会消失。

Answer 2

可能是IntelliJ找不到Java的路径...在IntelliJ中设置JDK（已安装）的路径

为插件开发设置Intellij IDEA - 找不到符号PathInfo
