In TopDownAnalyzerFacadeForJVM, we now always use the "load built-ins from module dependencies" behavior that was previously only enabled with the dedicated CLI argument -Xload-builtins-from-dependencies. However, sometimes we compile code without kotlin-stdlib in the classpath, and we don't want everything to crash because some standard type like kotlin.Unit hasn't been found. To mitigate this, we add another module at the end of the dependencies list, namely a "fallback built-ins" module. This module loads all built-in declarations from the compiler's class loader, as was done by default previously. This prevents the compiler from crashing if any built-in declaration is not found, but compiling the code against built-ins found in the compiler is still discouraged, so we report an error if anything is resolved to a declaration from this module, via a new checker MissingBuiltInDeclarationChecker. Also introduce a new CLI argument -Xsuppress-missing-builtins-error specifically to suppress this error and to allow compiling code against compiler's own built-ins. #KT-19227 Fixed #KT-28198 Fixed
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"
