Armin Aschoff reopened NIFI-9944:
---------------------------------

Hey [~mattyb149] - thanks for looking at this (and BTW all your many posts & blogs I've learned so much from!!)

Unfortunately this is _not_ a dupe of the copy/paste issue.  The failure I get is evident after following the workaround noted in that issue.

Also, affects the script when it is a script file.

> Create a new InvokeScriptedProcessor.
> Set Module Directory: ./scripts/jars/commons-text-1.6/
>  - have tried setting absolute & relative paths, paths to directories, paths to jar files, different versions of commons-text, trailing slash/no trailing slash, etc.  No differences
> Set script engine ECMAScript
> Write js script that tries to call a static method in commons-text.  Script can be either script file or script body, no difference
> Always get ClassNotFoundException error:
> {noformat}
> Component is invalid: 'ScriptValidation' validated against './scripts/testCsv.js' is invalid because Unable to load script due to java.lang.ClassNotFoundException: org.apache.commons.text.StringEscapeUtils{noformat}
>  
> Have tried Java.type and Packages. to try to access the class.
> Any/all help much appreciated as rapidly losing remaining hair!
> Sample script:
> {code:java}
> // base interface & class stuff
> var Processor = Java.type("org.apache.nifi.processor.Processor")
> var Relationship = Java.type("org.apache.nifi.processor.Relationship")
> var HashSet = Java.type("java.util.HashSet")
> var log = null
> // stuff to read/write flowfile content
> var InputStreamCallback = Java.type("org.apache.nifi.processor.io.InputStreamCallback")
> var OutputStreamCallback = Java.type("org.apache.nifi.processor.io.OutputStreamCallback")
> var IOUtils = Java.type("org.apache.commons.io.IOUtils")
> var StandardCharsets = Java.type("java.nio.charset.StandardCharsets")
> var StringEscapeUtils = Java.type("org.apache.commons.text.StringEscapeUtils")
> function getPropertyDescriptors() { return []}
> // =========== Define output relationships ================
> var REL_SUCCESS = new Relationship.Builder().name("success").description("FlowFiles that were successfully processed are routed here").build()
> function getRelationships() {
>     var r = new HashSet()
>     r.add(REL_SUCCESS)
>     return r
> }
> //=======================================
> // Execute the main script when triggered
> function onTrigger(context, sessionFactory) {

>         log.warn(test)
>         session.transfer(flowFile, REL_SUCCESS)
>     }    
>     session.commit()

> // ======================================================
> // Other functions required to satisfy interface contract
