When constructing method parameters be sure to include Flags.PARAMETER in the modifiers so that annotations with @Target(ElementType.PARAMETER) don't incorrectly cause compilation errors

Directory structure

  • bin - the Ceylon tools binaries
  • lib - compile/runtime dependencies
  • src - the Ceylon compiler backend sources
  • langtools - the OpenJDK Javac compiler sources
  • test-src - the Ceylon compiler backend unit tests
  • samples - a few sample Ceylon programs

Build the compiler and tools

First you must make sure you have built the ceylon.language, ceylon-spec and ceylon-module-resolver projects.

Go into ceylon.language first and run

ant clean publish

Then go into ceylon-module-resolver and run

ant clean publish

Then go into ceylon-spec and run

ant clean publish

To build and test the compiler return to ceylon-compiler and run

ant clean publish

To run the tests type

ant test

Note that some of the tests currently fail. See more info in README.tests.

Once built, the compiler lives in this jar:


If you want to build and run the Ceylon compiler in Eclipse then please see README.eclipse for setup instructions.

Running the compiler

The compiler can be run as follows:

build/bin/ceylonc -src samples -out build/ceylon-cars samples/helloworld.ceylon 

The -src argument to the compiler is required in order for the compiler to figure out each class's full name. It is a colon-separated path, much like javac's -sourcepath argument.

You can add -rep arguments to add module repositories. These can either be local paths or HTTP URLs.

Running your Ceylon program

In order to run your Ceylon program you'll need the https://github.com/ceylon/ceylon-runtime project. Clone that repository and follow the README instructions.

Generating the API documentation

The ceylondoc tool can be run as follows:

build/bin/ceylond -out api-docs -src ../ceylon.language/languagesrc/current ceylon.language

Building the project on Mac with JDK7

  1. Download JDK7: http://jdk7.java.net/download.html

  2. Unpack .dmg

  3. export JAVA_HOME

    Skywalker:ceylon-compiler alesj$ export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.7.0_06.jdk/Contents/Home/

    Skywalker:ceylon-compiler alesj$ java -version java version "1.7.0_06-ea" Java(TM) SE Runtime Environment (build 1.7.0_06-ea-b12) Java HotSpot(TM) 64-Bit Server VM (build 23.2-b03, mixed mode)

  4. Build it (ant clean publish)
