evalScript
Evaluates a raw Java script string, prepending any registered import declarations.
Each variable added with add is assigned to the public field of the same name in the script's class, so that class must declare a public, assignable field of a compatible type for every added variable.
Return
the result of the script evaluation, or null if the script evaluates to null
Parameters
script
the Java source code to evaluate
verbose
if true, logs the generated script before evaluation
Throws
if script contains a literal JVM-termination call, fails to compile or run, or a variable cannot be assigned to its field
