Ceylon IDE for Eclipse

This project is an Eclipse-based IDE for the Ceylon programming language.

For more information about Ceylon IDE for Eclipse, go to:

https://ceylon-lang.org/documentation/ide/eclipse/

Installing the Ceylon plugin

Installing from the main update site

The simplest way to install the Ceylon IDE Eclipse plugin is simply to follow the instructions found here:

http://ceylon-lang.org/documentation/1.2/ide/install

Installing nightly builds from Jenkins

Nightly builds are available in this update site: https://ci-ceylon.rhcloud.com/job/ceylon-ide-eclipse/ws/site/target/repository/

Note that this is the current master, which may contain bugs.

Installing from a local snapshot site built with Tycho/Maven 3

If you want to have an up-to-date version of the Ceylon IDE based on the latest code of all Ceylon projects, this is the recommended method.

  1. Make sure that you are using Java 7 or 8 by running javac -version.

  2. Make sure that ant (latest version of Ant) and mvn (some Maven version from 3.0.5 to 3.2.1) can be run on the command line.

  3. First clone the Ceylon command line distribution locally. Type the following command in the directory of your choice:

    git clone https://github.com/ceylon/ceylon.git

    This has created the ceylon local repository.

  4. Next, the following required projects should also be cloned: Ceylon SDK, Ceylon Formatter, Java To Ceylon Converter, and Common code for Ceylon IDEs. To clone all these projects at once, go to the ceylon/ directory ceated in the previous step, and type:

    ant setup-sdk setup-ide

    This command will have cloned the following Git repositories:

    • ceylon-sdk
    • ceylon.formatter
    • ceylon-ide-common
    • ceylon.tool.converter.java2ceylon
    • ceylon-ide-eclipse

    at the same directory level as the ceylon local repository.

  5. Finally, to build all the above projects, stay in the .../ceylon/ directory and type:

    ant clean-all dist sdk eclipse

  6. The directory .../ceylon-ide-eclipse/site/target/repository now contains an Eclipse update site you can install from. The update process is decribed at http://ceylon-lang.org/documentation/1.2/ide/install/ but use the full path to this directory instead as the URL of the update site.

Developing the Ceylon plugin

Building project per project

If you make modifications on one of Ceylon IDE's dependencies, you can rebuild projects separately:

  1. Build a full Ceylon distribution locally (see here for more details):

    • In the .../ceylon directory run: ant clean dist
    • This should have produced an eclipse update site at the following path:

    .../ceylon/dist/osgi/build/dist

  2. Build the Ceylon SDK locally (see here for more details):

    • In the .../ceylon directory run: ant clean-sdk sdk
    • This should have produced an eclipse update site at the following path:

    .../ceylon-sdk/osgi/dist

  3. Build the Ceylon Formatter locally (see here for more details):

    • In the .../ceylon.formatter directory run: ant clean publish ide-quick
    • This should have produced an eclipse update site at the following path:

    .../ceylon.formatter/osgi/dist

  4. Build the Ceylon IDE Common components locally (see here for more details):

    • In the .../ceylon-ide-common directory run: ant clean publish ide-quick
    • This should have produced an eclipse update site at the following path:

    .../ceylon-ide-common/osgi/dist

  5. Build the Java To Ceylon Converter components locally (see here for more details):

    • In the .../ceylon.tool.converter.java2ceylon directory run: ant clean publish ide-quick
    • This should have produced an eclipse update site at the following path:

    .../ceylon.tool.converter.java2ceylon/osgi/dist

  6. From the directory .../ceylon-ide-eclipse, type:

    mvn clean install -fae

    Faster alternative: To skip tests completely you can run:

    mvn clean install -DskipTests

Developing the plugin inside Eclipse

This implies some additional complexity, and is only useful if you want to debug the Ceylon IDE plugin.

Preliminary remark: Parts of the Ceylon IDE project itself are written in Ceylon. Thus, in order to develop the Ceylon IDE plugin, you must have a previous version of the plugin installed in your main Eclipse (preferably downloaded from the stable update site, or built with Maven).

  1. Perform steps 1 to 4 of section : Building with Tycho / Maven 3.

  2. Start with a (preferably clean) install of Eclipse Kepler, Luna or Mars.

    http://www.eclipse.org/downloads/

  3. Install the following feature: Graphical Editing Framework Zest Visualization Toolkit SDK. It is available here:

    http://download.eclipse.org/tools/gef/updates/releases/

  4. Make sure you have the following feature: Eclipse Plug-in Development Environment. It is normally included inside the Eclipse Standard Package.

  5. Install a previous version of the Ceylon IDE, preferably downloaded from the stable update site (see here), or built with Maven (see here).

  6. Use File > Import... > Existing Projects into Workspace to import the Java and Ceylon Eclipse projects that are in these directories:

    • .../ceylon-ide-common
    • .../ceylon-ide-eclipse/plugins/org.eclipse.ceylon.ide.eclipse.ui.jdt.debug.fragment
    • .../ceylon-ide-eclipse/plugins/org.eclipse.ceylon.ide.eclipse.ui
    • .../ceylon-ide-eclipse/plugins/org.eclipse.ceylon.test.eclipse.plugin
    • .../ceylon-ide-eclipse/plugins/org.eclipse.ceylon.ide.eclipse.android.plugin

  7. Add the following folder as a local update site in your Eclipse Available Software Sites list:

    .../ceylon-ide-eclipse/UpdateSiteForBinaryDependencies/

    From this new update site, install only the elements that are under the categories whose name contains : '- Only Binary Dependencies'. This provides (as OSGI bundles) only the external archives required by the various siblings projects required by the IDE plugin (jboss modules, antlr-runtime v4, etc ...).

  8. Use File > Import... > Existing Projects into Workspace to import the Eclipse projects that are in these directories:

    • the ceylon-dist-osgi project found at the following location:

      .../ceylon/dist/osgi

    • the ceylon-dist-osgi-embedded-repository project found at the following location:

      .../ceylon/dist/osgi/embeddedRepository

    • all the required bundle-proxys projects found under the following location:

      .../ceylon-ide-eclipse/required-bundle-proxies

    Important Note:

    Since the Ceylon Distribution modules have circular dependencies on each others, it happens that those circular dependencies are reproduced by the ceylon-dist-osgi and bundle-proxys projects.

    In order to be able to build you projects, you will have to allow cycles in the Java build paths by setting the following Eclipse preference:

    Java > Compiler > Build > Circular Dependencies to warning

  9. During the development, you should be aware of these rules:

    • If you change some of the fixed jars included in the Ceylon distribution (such as org.antlr, org.apache.commons.logging, etc...), then you should :
      • rebuild/publish the distribution by running the ant clean publish ide-quick command in the ceylon/dist directory,
      • update, inside Eclipse, the Ceylon Distribution Binary Dependencies Feature feature from the .../ceylon/dist/osgi/build/dist update site.
    • If you have modified code inside one of the projects required by the Ceylon IDE plugin (distribution project, SDK, formatter, java2ceylon converter, ceylon-ide-common, ...), you should:
      • rebuild/publish the modified project by running the ant clean publish ide-quick command in the project directory,
    • Each time you rebuild/publish one of the projects required by the Ceylon IDE plugin (distribution project, SDK, formatter, java2ceylon converter, ceylon-ide-common, ...), you should:
      • refresh inside Eclipse the ceylon-dist-osgi project, as well as the bundle proxy projects related to the rebuilt project. This is necessary so that Eclipse will see the changes, especially when running/debugging the CeylonIDE.

  10. If you want to modify / add IDE tests, you should also add the test plugin:

    • Add the SWTBot Eclipse features, which are required to compile and run the Ceylon IDE interactive tests. Install all the features available at the following update site: http://download.eclipse.org/technology/swtbot/releases/latest/
    • Use File > Import... > Existing Projects into Workspace to import the project from this root directory: .../ceylon-ide-eclipse/tests/org.eclipse.ceylon.ide.eclipse.ui.test

  11. Select the org.eclipse.ceylon.ide.eclipse.ui project and run it using Run > Run As > Eclipse Application. Now go to the new instance of Eclipse.

Building the next maintenance update of the last released version

By default, when building the plugin from Maven and developing it, all the code is built against the master branch of all the dependencies (incuding the Ceylon command line distribution). However, after a release, we create GitHub maintenance branches for the two following projects:

These branches allow pushing only changes that are fully compatible with the release available at the main updatesite: http://ceylon-lang.org/eclipse/updatesite/.

In order to work on these branches and build these 2 projects against the dependencies found in the release update site (instead of building against the local master branch of each project), you should:

The generated update site generated in directory .../ceylon-ide-eclipse/site/target/repository now contains a maintenance release fully compatible with the last release published in the official Ceylon Eclipse update site

In order to come back to the master branches, run the following command from the .../ceylon/dist directory:

ant eclipse-switch-back-to-master

Updating the Ceylon version

For proxy bundles, I used:

for f in *-1.1.0.?ar; do newf=${f/1.1.0/1.1.1}; if test \! -d $newf; then mkdir $newf; fi; cp $f/{.classpath,.project,.gitignore} $newf/; perl -pi -e 's/1\.1\.0/1.1.1/g' $newf/{.classpath,.project,.gitignore}; done

Pushing a new release onto the development update site

  1. Build with Tycho/Maven 3 (see previous section)

  2. Copy (through sftp) the content of the directory site/target/repository onto the server:

    www.ceylon-lang.org

    to the following directory:

    /var/www/downloads.ceylonlang/ide/dev
