This page is intended to give existing projects a jumpstart for setting up a Tycho build.

While each project is different, there are some common steps:

Scaffolding: generate pom.xml files

Maven needs pom.xml files to drive the build. See Generating POM files on how to generate an initial skeleton for these files.

Manual adjustments

In the generated top-level (parent) pom.xml, it's a good idea to globally define the tycho version to use

<properties>
  <tycho-version>0.18.0</tycho-version>
</properties>

so you can reference it using ${tycho-version} anywhere in the child pom.xml files e.g. when configuring tycho plugins. See maven project inheritance.

In case you have deeply nested projects and used several generate-poms invocations, add a top-level parent pom.xml and reference it as parent from the intermediate parent poms. Also, adjust the modules to be built (see maven project aggregation).

Adding p2 repositories to resolve external dependencies

Almost every project has external dependencies it needs to compile against. Add all p2 repositories you need for compilation or runtime in the parent pom like in pom.xml the following snippet:

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

See Tycho Reference card

Getting tests to run

If your test bundle symbolic names end with .tests, the pom generator will acccordingly define

<packaging>eclipse-test-plugin</packaging>

This will tell Tycho to scan for test classes and execute them during build. Note that scanning is using class naming convention

**/Test*.java **/*Test.java **/*TestCase.java

For details, see the Tycho Surefire docs
