Tycho/Reference Card

This page provides snippets for using Tycho. You may also wish to see:

Enabling tycho

   <properties>
      <tycho-version>0.16.0</tycho-version>
   </properties>

   <build>
      <plugins>
         <plugin>
            <groupId>org.eclipse.tycho</groupId>
            <artifactId>tycho-maven-plugin</artifactId>
            <version>${tycho-version}</version>
            <extensions>true</extensions>
         </plugin>
      </plugins>
   </build>
Note that this is usually defined in the parent POM in under build / plugins

Repository providing the context of the build

Specify a repository to get pre-built pieces from. Multiple repositories can be specified. See also target file section.

   <repository>
      <id>eclipse-indigo</id>
      <layout>p2</layout>
      <url>http://download.eclipse.org/releases/indigo</url>
   </repository>

Target file providing the context of the build

Use a target platform to get pre-build pieces from. The target platform file can be edited using Eclipse PDE editor.

          <plugin>
            <groupId>org.eclipse.tycho</groupId>
            <artifactId>target-platform-configuration</artifactId>
            <version>${tycho-version}</version>
            <configuration>
              <target>
                <artifact>
                  <groupId>${project.groupId}</groupId>
                  <artifactId>${project.artifactId}</artifactId>
                  <version>${project.version}</version>
                  <classifier>TargetFileNameWithoutExtension</classifier>
                </artifact>
              </target>
            </configuration>
          </plugin>

Target runtime environment

Note.png
This paragraph is a stub - not verified by a Tycho guru


Specify which environments your software should be built for (os/ws/arch). This will determine the set of platform dependent fragments to be included in the project's dependencies. If you omit this the build will say

 No explicit target runtime environment configuration. Build is platform dependent

Target runtime environments are specified like this:

      <plugin>
        <groupId>org.eclipse.tycho</groupId>
        <artifactId>target-platform-configuration</artifactId>
        <version>${tycho-version}</version>
        <configuration>
          <environments>
            <environment>
              <os>win32</os>
              <ws>win32</ws>
              <arch>x86</arch>
            </environment>
            <environment>
              <os>linux</os>
              <ws>gtk</ws>
              <arch>x86_64</arch>
            </environment>
            <environment>
              <os>macosx</os>
              <ws>cocoa</ws>
              <arch>x86_64</arch>
            </environment>
          </environments>
        </configuration>
      </plugin>

It seems this specification accepts all os/ws/arch values exactly as they are understood by OSGi.

Setting up the tests to run

    <groupId>org.eclipse.tycho</groupId>
    <artifactId>tycho-surefire-plugin</artifactId>
    <version>${tycho-version}</version>
    <configuration>

           <argLine>-Xmx512m</argLine>

Setting application arguments

In the configuration section for the test plug-in

           <appArgLine>-nl en</appArgLine>

Bundle start level

           <bundleStartLevel>
              <bundle>

                 <level>1</level>
                 <autoStart>true</autoStart>
              </bundle>
           </bundleStartLevel>

Selecting JDK

Since version 0.13 tycho-surefire-plugin can use Maven Toolchains to run tests with a specific version of JDK independent from the one Maven is running with.

  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-toolchains-plugin</artifactId>
    <version>1.0</version>
    <executions>
      <execution>
        <phase>validate</phase>
        <goals>
          <goal>toolchain</goal>
        </goals>
      </execution>
    </executions>
    <configuration>
      <toolchains>
        <jdk>
          <version>1.5</version>
          <vendor>sun</vendor>
        </jdk>
      </toolchains>
    </configuration>
  </plugin>

Source Bundles

To generate source bundles, you need to execute goal "plugin-source" of plugin tycho-source-plugin:

  <build>
    <plugins>   
      <plugin>
        <groupId>org.eclipse.tycho</groupId>
        <artifactId>tycho-source-plugin</artifactId>
        <version>${tycho-version}</version>
        <executions>
          <execution>
            <id>plugin-source</id>
            <goals>
              <goal>plugin-source</goal>
            </goals>
          </execution>
        </executions>
      </plugin>
    </plugins>
  </build>

For convenience, you can do this only once in your parent POM. A source bundle (with ".source" appended to the Bundle-SymbolicName) will be generated for each module inheriting from this parent which has packaging type eclipse-plugin or eclipse-test-plugin.

You can then reference source bundles as normal bundles in other MANIFEST.MF or feature.xml by referencing with their Bundle-Name: <bundle.name>.source.

Source Features

On an existing eclipse-feature, you can create the associated source feature by using the following plugin:

<plugin>
	<groupId>org.eclipse.tycho.extras</groupId>
	<artifactId>tycho-source-feature-plugin</artifactId>
	<version>${tychoExtrasVersion}</version>
	<executions>
		<execution>
			<id>source-feature</id>
			<phase>package</phase>
			<goals>
				<goal>source-feature</goal>
			</goals>
		</execution>
	</executions>
</plugin>

Source feature is named <featureId>.source.

Generating POM files

If you have an existing build which you want to migrate to tycho, you can generte the required pom.xml files using

mvn org.eclipse.tycho:tycho-pomgenerator-plugin:generate-poms -DgroupId=<MY.GROUPID>

This will scan the filesystem starting from the current directory for bundles (i.e. MANIFEST.MF files) and features (feature.xml files) and generate the corresponding pom.xml files. It assumes test bundles have a suffix ".tests". You can change this default by specifying -DtestSuffix=.mytestBundleSuffix

To address e.g. version 0.15.0-SNAPSHOT of tycho:

mvn org.eclipse.tycho:tycho-pomgenerator-plugin:0.15.0-SNAPSHOT:generate-poms -DgroupId=<MY.GROPUID>
