lie algebras - Weyl group Invariants

What are the generators of $mathbb C[V^m]^W$, where $W$ is the Weyl group
of type $E_6, E_7, E_8$, V^m denote 'm' (m > 1) copies of the Cartan subalgebra
and the action is the diagonal action?



Is there any reference where I can find the generators explicitly?
