New and Noteworthy

Complete list of bug fixes and enhancements in 1.1.0

Java 9

• Tycho's dependencies have been updated where necessary to support running the build using Java 9

Compiler

• the JDT compiler shipped with Tycho has been updated to Photon M4
• Compilation both using Java 9 as well as using previous Java versions but compiling against Java 9 ( with useJDK=BREE) is supported now
• Changes for useJDK=BREE:
  • Usage of a JRE directory JAVA_HOME/jre in toolchains.xml is still supported but deprecated in favour of simply using JAVA_HOME. In particular, JAVA_HOME is expected by other maven plugins integrated with toolchains.xml

Packaging

• plexus-archiver was updated to version 3.4 (bug 514119)
• commons-compress was updated to version 1.15 (bug 514119)

Release and Versioning

• Support for using maven-release-plugin with Tycho has been contributed (bug 342893), see release workflow docs
• Added new goal mvn org.eclipse.tycho:tycho-versions-plugin:update-eclipse-metadata (bug 342893) which will update MANIFEST/feature.xml/product versions based on their respective pom versions. This is useful e.g. if you changed pom versions using maven-release-plugin. For more details about using the maven release plugin with Tycho see Tycho/Release_Workflow.
