Regardless whether I am building with Java 1.5 or 1.6, regardless what I set compileJava.targetCompatibility and compileGroovy.targetCompatibility to, the .class files generated by my project (using groovy plugin) are always 1.5 (major/minor version 49/0) and can be run with 1.5 JRE.
The starting compileJava.targetCompatibility and compileGroovy.targetCompatibility values when using the groovy plugin are both 1.6. So why does everything always come out 1.5-compatible?
According to what http://www.gradle.org/docs/current/dsl/org.gradle.api.tasks.compile.GroovyCompile.html says about compileGroovy.targetCompatibility, my .classes built with setting of 1.6 should not be executable by 1.5 but they are.
Anybody know why?
My goal is to publish 1.5-compatible jars, but I want to code to enforce that. I don’t want to depend on what looks to be unintended and possibly to-be-fixed behavior.
I’m using Gradle 1.2.
