List of bug fixes and enhancements in 0.14.0

0.14.0-SNAPSHOT versions

Currently, there are no official snapshot versions of Tycho available (see bug 360628).

As a workaround, Sonatype Inc. provides an additional CI build of the Tycho sources and makes that result available in this Maven repository. To use this CI build result, add the following snippet to your (parent) POM and set Tycho version to 0.14.0-SNAPSHOT.

New and Noteworthy

• Tycho index files in the local maven repository and tycho in general should now be multi-process safe (this is what our concurrent test suite is telling us at least) No more cryptic error messages when two concurrent build jobs modify the same local repository index file
• In maven offline mode, tycho should now be really offline
• tycho-surefire-plugin was ported from surefire 2.4.3 to 2.10 and now respects the surefire -DskipTests switch
• .tar.gz has been added as a product archive format which can be built with packaging type eclipse-repository
• Support for license features has been added
• Full support for bundle runtime execution environments
  • List of accessible system packages of bundle runtime execution environment is now respected during project dependency resolution and java compilation. This makes sure that bundles do not accidentally reference JRE classes that may not be available in all runtime environments supported by the bundles.
  • If bundle project supports multiple runtime execution environments, Tycho will use the list of packages from the most restricted environment by default. Build target execution environment can be specified explicitly using new <executionEnvironment> target platform configuration parameter. For backwards compatibility with PDE, jre.compilation.profile build.properties property is supported too.
  • Additionally, tycho-compiler-plugin can be configured to use different JDK libraries for different bundle runtime execution environment. Additional JDKs are configured using Maven toolchains.xml, where toolchain id element is matched to execution environment profile name. For example

 <toolchains>
  <toolchain>
     <type>jdk</type>
     <provides>
         <id>J2SE-1.5</id>
     </provides>
     <configuration>
        <jdkHome>/path/to/jdk/1.5</jdkHome>
     </configuration>
  </toolchain>
 </toolchains>
