Hi

I have problem with compiling my code through Tycho 0.20.0 / JDK8. I use
new Java 8 language features. Everything works fine under Eclipse (4.4 M7).

Thanks

Hi,

tycho 0.20.0 uses a jdt-core version which does not support java8 yet -
you could give 0.21.0-SNAPSHOT a try and or force tycho to use a
different newer jdt-version.

The process for that is like this:
a) install org.eclipse.jdt.core and org.eclipse.jdt.compiler.apt from
the I-Build repos into your local m2-repo

b) update your root-pom to force useage of the local compiler
