List of bug fixes and enhancements in 0.16.0

New and Noteworthy

New Features

• Support for parallel test execution with JUnit >= 4.7 has been added.
  If you use Junit >= 4.7, you can now have test classes or methods executed by several threads in parallel by adding -Dparallel=classes|methods|both on the commandline or by configuring
  

  <plugin>
     <groupId>org.eclipse.tycho</groupId>
     <artifactId>tycho-surefire-plugin</artifactId>
     <version>${tycho-version}</version>
     <configuration>
       <parallel>classes|methods|both</parallel>
     </configuration>
  </plugin>
  

  Executing tests in parallel can be useful e.g. if you have long-running integration tests which are not CPU-bound.
  Under the hood, this feature was enabled by porting the junit4.7 surefire provider to Tycho.

• Reproducible Version Qualifiers
• A new plugin to validate target platforms. This plugin takes as input one or several target platforms and ensures they can be resolved, fails otherwise

  <plugin>
     <groupId>org.eclipse.tycho.extras</groupId>
     <artifactId>target-platform-validation-plugin</artifactId>
     <version>${tychoExtrasVersion}</version>
     <executions>
        <execution>
           <phase>validate</phase>
           <goals>
              <goal>validate-target-platform</goal>
           </goals>
           <configuration>
              <targetFiles>
                 <param>indigo.target</param>
                 <param>juno.target</param>
              </targetFiles>
              <failOnError>true</failOnError>
           </configuration>
        </execution>
     </executions>
  </plugin>

Improvements and Fixes

• Providing credentials for a p2 repository specified in a target file is now more convenient – the use of the non-standard id attribute in target files is no longer necessary (bug 377086).
• Access to p2 repository can be redirected to a mirror location. This now works for both target files and repositories specified in the POM (bug 356016).
• tycho-compiler-plugin now has a boolean option requireJREPackageImports which will fail the build if set to true and packages provided by the JDK are not explicitly imported.
  This is the design-time equivalent of setting equinox runtime option osgi.compatibility.bootdelegation=false.
• Support for test frameworks is extensible now. This means you can add support for test frameworks other than JUnit if you provide an implementation of TestFrameworkProvider.
• The tycho-p2-director-plugin can now create product installations which have meta-requirements on the installer. This for example allows to execute custom touchpoint actions during the installation. See the integration test for an example.
