Query on developing OpenJDK with IntelliJ

[Weijun Wang]

This is how I did.

1. Build jdk9/dev to an exploded-image, so you have build/<platform>/jdk.

2. mkdir jdk/classes to trick IntelliJ IDEA this is a JDK.

3. Add this jdk directory as an SDK. In classpath and sourcepath, add 
the modules you are interested in (classpath to 
<build>/jdk/modules/mod_name, sourcepath to 
<src>/jdk/src/mod_name/share/classes).

4. Create an empty project, add whatever jdk src directory you like into 
its Modules/Source, or add the whole jdk there, and "Mark Directory as" 
sources for each sub-directory. You can manually edit <content> and 
<sourceFolder> in the iml file.

5. Done.
