Java 11 removed a number of modules which broke compilation/tests/resolving deps when the bundle has lower BREE as they were resolved from the BREE profile. Now Tycho will check if runtime Java is 11+ and if it differs from bundle's EE - in this case it will resolve deps with current runtime's EE.

If you have configured Tycho to create [[Tycho/Reproducible Version Qualifiers|reproducable version qualifiers]], then Tycho will calculate the qualifier from the underlying git history. This can take quite a while on git repositories with a big history. In Tycho 1.4 the history retrieval has been optimized, and we have seen the execution time drop down from several seconds to less than a second on a big repository. This calculation is done for each module in an aggregator. If you build big aggregators with many modules, then you may gain some minutes of build time just by upgrading Tycho. {{bug|544005}}

Objectweb ASM update

ObjectWeb ASM has been updated to version 7.0 from 5.0.3 which provides Java 11 compatibility in artifactcomparator. Note: Due to upstream no longer producing org.ow2.asm:asm-debug-all Tycho now requires org.ow2.asm:asm-tree and org.ow2.asm:asm-util. bug 543850

Resolving Java 11 removed modules

Java 11 removed a number of modules which broke compilation/tests/resolving deps when the bundle has lower BREE as they were resolved from the BREE profile. Now Tycho will check if runtime Java is 11+ and if it differs from bundle's EE - in this case it will resolve deps with current runtime's EE. Note: Some additional bundles may need to be added to the target platform to replace the removed JDK modules. bug 541403

Performance improvement

If you have configured Tycho to create reproducable version qualifiers, then Tycho will calculate the qualifier from the underlying git history. This can take quite a while on git repositories with a big history. In Tycho 1.4 the history retrieval has been optimized, and we have seen the execution time drop down from several seconds to less than a second on a big repository. This calculation is done for each module in an aggregator. If you build big aggregators with many modules, then you may gain some minutes of build time just by upgrading Tycho. bug 544005
