[tycho-user] Bundle-RequiredExecutionEnvironment: JavaSE-1.7 problem

["Blackburn, James (London)" <jblackburn@xxxxxxx>]

Hi All,

 

I’m unable to get tycho to build a bundle that has Java 7 specified in the manifest’s execution environment.

  Bundle-RequiredExecutionEnvironment: JavaSE-1.7

The Java on my path is Java 7, the bundle builds correctly within Eclipse’s PDE.   The problem doesn’t occur if I use JavaSE-1.6 or less (though some files fail to compile as I’m using new nio features).

 

Tycho 0.14.0 gives me this error:

Does anyone know how can I influence the RequiredExecutionEnvironment?
