The problem:
I have a Xtext project with a Xcore model. In Eclipse, it works fine: the model is generated without problems.
The Xcore model contains among other things this fragment:
class RuleSystem {
contains Rule[] rules
}
class Rule {
}
I'm attempting to automate the generation using gradle and the xtext gradle plugin. I based my build.gradle on the example project at https://github.com/ghillairet/xcore-gradle-example. The build executes successfully, but the generated code differs in that it's missing type parameters:
Where Eclipse would generate
the gradle build generates:
etc. (for every such instance). This of course leads to a lot of warnings and some type errors.
The build.gradle file I'm using:
plugins {
id "org.xtext.xtext" version "0.3.26" // used to build Xcore model
id "org.xtend.xtend" version "0.4.14"
id "java"
id "eclipse"
}
group 'rapanui'
version '0.1.0-alpha.1'
sourceCompatibility = 1.8
targetCompatibility = 1.8
jar.manifest {
from 'META-INF/MANIFEST.MF'
}

mavenCentral()
}

Any ideas on how to fix this? Am I missing any dependencies? Or doing something wrong?
Any help would be greatly appreciated.

I just looked at the build output again, and found that hidden between the output of the generated java files there are a lot of lines like this:
A problem was detected while parsing a Java file
Line 151: Syntax error, parameterized types are only available if source level is 1.5 or greater
Line 151: Syntax error, parameterized types are only available if source level is 1.5 or greater
Line 153: Syntax error, parameterized types are only available if source level is 1.5 or greater
Line 155: Syntax error, parameterized types are only available if source level is 1.5 or greater
Line 157: Syntax error, parameterized types are only available if source level is 1.5 or greater
Any idea what causes this? I did set sourceCompatibility to 1.8 in the gradle file.
