	 * Sets the classpath of this project using a list of classpath entries. In particular such a classpath may contain

	 * classpath variable entries. Classpath variable entries can be resolved individually (see <code>JavaCore#getClasspathVariable</code>),

	 * or the full classpath can be resolved at once using the helper method <code>getResolvedClasspath</code>.

	 * A classpath variable provides an indirection level for better sharing a classpath. As an example, it allows

	 * a classpath to no longer refer directly to external JARs located in some user specific location. The classpath

	 * can simply refer to some variables defining the proper locations of these external JARs.
