IntelliJ IDEA doesn't run javac, therefore you can't see the command line.

Compiler API is used directly from Java code. If you enable debug logging for build.log file, you may find some more details how the modified and dependent files are compiled and what options are used.

Sample debug log line:

[  41011]  DEBUG - s.incremental.java.JavaBuilder - Compiling chunk [stopme] with options: "-g -deprecation -proceedOnError -encoding UTF-8 -source 1.8 -target 1.8 -proc:none"
