Method Detail

getModuleURLsForClasspath

public URL[] getModuleURLsForClasspath(String[] modulePaths,
                                       ComponentLog log)

Scans the given module paths for JARs. The path itself (whether a directory or file) will be added to the list of returned module URLs, and if a directory is specified, it is scanned for JAR files (files ending with .jar). Any JAR files found are added to the list of module URLs. This is a convenience method for adding directories full of JAR files to an ExecuteScript or InvokeScriptedProcessor instance, rather than having to enumerate each JAR's URL.

Specified by:

getModuleURLsForClasspath in interface ScriptEngineConfigurator

Parameters:

modulePaths - An array of module paths to scan/add

log - A logger for the calling component, to provide feedback for missing files, e.g.

Returns:

An array of URLs corresponding to all modules determined from the input set of module paths.
