Hello,

Currently I have an xtext maven project without plugin support, which I use standalone. I wonder about the many dependencies at runtime. Is it possible to reduce the dependencies? Need the project really guice, guava and xtend at runtime?

cause xtext relys on guice to do dependency injection.

Okay thanks.
I thought it's just for the injection during the code generation. And during the runtime xtext don't need it.

Dear all.

My mave dependencies for standalone application (run-time, not DSL compiler) are:

		<dependency>
			<groupId>org.eclipse.xtext</groupId>
			<artifactId>org.eclipse.xtext.xbase.lib</artifactId>
		</dependency>
		<dependency>
			<groupId>org.eclipse.xtend</groupId>
			<artifactId>org.eclipse.xtend.core</artifactId>
		</dependency>
		<dependency>
			<groupId>com.google.guava</groupId>
			<artifactId>guava</artifactId>
		</dependency>
		<dependency>
			<groupId>javax.inject</groupId>
			<artifactId>javax.inject</artifactId>
		</dependency>

You could remove Xtend if you are not using it.

All the best.
Stéphane.

And how you said xtext use DI itself, so i think you cannot get rid of the guice dependency.

e.g. i use the IResourceValidator to validate the resource and get the erros.
The ResourceValidateImpl use injection
