A complex vector bundle is a vector bundle with respect complex vector spaces.
A omplex vector bundle with complex 1-dimensional fibers is a complex line bundle.
The Oka-Grauert principle states that for any Stein manifold $X$ the holomorphic and the topological classification of complex vector bundles on $X$ coincide. The original reference is (Grauert 58).
