Tycho/Release Notes/0.20

Tycho 0.20.0 adds support for building product distributions which have features installed at root level, so that they can be updated independently of the product. This was a highly wanted feature - with 18 votes at the time this was implemented. To install a feature at root level, just mark it with installMode="root" in the product file (see Tycho/eclipse-repository for details).

New and Noteworthy

List of bug fixes and enhancements in 0.20.0


  • Product files can now specify that a feature shall be installed at root level in the installation (bug 361722). These features can be updated (or even uninstalled) independently from the product. See Tycho/eclipse-repository for details on the syntax.
  • The tycho-pack200a:normalize goal now has a skip flag to allow skipping normalization when skipping signing (bug 421301)

Test Execution

  • Rely on the 'abstract' modifier to identify abstract test classes rather than using a naming convention.This means that test classes named **/Abstract*Test.class or **/Abstract*TestCase.class are no longer generally excluded from the test execution, but only if they are marked as 'abstract' (see bug 389509).
  • More reliably terminate forked test processes (bug 427556). Before being fixed, this bug could have caused orphaned test execution JVM processes to live on forever, consuming resources and accumulating system load.
