Custom Keyword plugin with external dependency

Hi, Im trying to create an Custom keywords plugin. It turns out that my keyword will use some external jars. In this case i will use org.apache.poi jar that i already added to Driver folder. My build.gradle looks like plugins { id 'java' id 'groovy' id 'com.github.johnrengelman.shadow' version '4.0.4' id "com.katalon.gradle-plugin" version "0.0.6" } repositories { jcenter() mavenCentral() } sourceSets { main { groovy { srcDirs = ['Keywords', 'Include/scripts/groovy']…

[libra.soumya17]

yes i checked this as well. I dont have any array param, so dont think the length could be an issue.

F.Y.I

See

Custom Keyword plugin with external dependency

You have a single whitespace between ‘param’ and ‘2’, but why? This single whitespace will confuse Groovy. Unfortunately Groovy failed to blame your coding mistake, got panicked, threw an Exception that doesn’t make sense. You should write: , String param2,

You should check the method signature of your Custom Keywords.

I fixed this error.
In my project there were issues related to import packages, signatures, and minor other issues. I fixed these one by one and plugin worked.
Katalon should change this message, and also in such cases may be throw error while building plugin only.
