IC: Compute symbols impacted by classpath changes
Incremental compilation has 4 key steps:
1. Compile changed/impacted files
2. Detect symbols that have changed after compiling
3. Detect symbols that are impacted by the changed symbols
4. Based on the changed-or-impacted symbols, identify files that need
to be recompiled. Go back to step 1.
Normally, step 2 and 3 are done together when the changed symbols
and impacted symbols are in the same module.
However, if the changed symbols and impacted symbols are in different
modules (e.g., a `Subclass` in lib1 extends a `Superclass` in lib2),
we currently do not compute symbols in the current module that are
impacted by changes in another module (step 3 above).
This is the case for both the new IC and the old IC.
In this commit, we will compute impacted symbols for the new IC. We can
fix the old IC later if necessary (they can't be fixed together easily).

Kotlin Libraries
This part of the project contains the sources of the following libraries:
- kotlin-stdlib, the standard library for Kotlin/JVM, Kotlin/JS and its additional parts for JDK 7 and JDK 8
- kotlin-reflect, the library for full reflection support
- kotlin-test, the library for multiplatform unit testing
- kotlin-annotations-jvm, the annotations to improve types in the Java code to look better when being consumed in the Kotlin code.
These libraries are built as a part of the root Gradle project.
Kotlin Maven Tools
This area of the project is the root for Maven build.
You can work with the maven modules of this maven project in IDEA from the root IDEA project. After importing you'll be able to explore maven projects and run goals directly from IDEA with the instruments on the right sidebar.
Building
You need to install a recent (at least 3.3) Maven distribution.
Before building this Maven project you need to build and install the required artifacts built with Gradle to the local maven repository, by issuing the following command in the root project:
./gradlew install
Note: on Windows type
gradlewwithout the leading./
This command assembles and puts the artifacts to the local maven repository to be used by the subsequent maven build. See also root ReadMe.md, section "Building".
Then you can build maven artifacts with Maven:
mvn install
If your maven build is failing with Out-Of-Memory errors, set JVM options for maven in MAVEN_OPTS environment variable like this:
MAVEN_OPTS="-Xmx2G"
