[intellij-multiproject] is a MIT-licensed shell script to make it easy to embed other IntelliJ projects that are libraries within a master project. To use it from another project, add it as a submodule in tools/intellij-multiproject then ln -s tools/intellij-multiproject/intellij-multiproject-git-hook git-pull-hook.

• Modules
• Artifacts (output paths are re-written)
• Library definitions (subprojects overwrite master; last one wins)

• Copyright profiles are not combined (use a scope to exclude the library code)
  • They could be with some work

• It is not possible to combine the version of Java, or the Java SDKs
  • This can cause problems if there is a difference in the version of Java in the master project and sub-projects
  • It can be overcome by explicitly setting the module's JDK and Java version
• Output path overrides may not work as expected, but it is rare to override a project output path with a per-module one for libraries
• Compiler settings are not combined
• Run configurations are not combined
• Code style settings are not combined (it is recommended to stick to make major edits using sub-projects)
• Inspection Profiles are not combined
