Bug 430989

Description Fabian Schöppl 2014-03-24 06:50:16 EDT

I am trying to build a Java 8 eclipse plug-in project using tycho 0.20.0. The compilation stops with the following error message:

[ERROR] Failed to execute goal org.eclipse.tycho:tycho-compiler-plugin:0.20.0:compile (default-compile) on project MyBundle: Fatal error compiling: target level should be comprised in between '1.1' an
d '1.7' (or '5', '5.0', ..., '7' or '7.0') or cldc1.1: 1.8 -> [Help 1]

I run the following pom-file via "mvn clean compile install":

I've attached the MyBundle-eclipse-plug-in (created with Eclipse Luna M6 4.4.0M6) to this bug.
