how to add jar to classpath to be used in script runner external scripts



I want to add http-builder jar so I could use it in script runner, 

Where should I put it so i could just import it . 

I tried this.class.classLoader.rootLoader.addURL( new URL("file:///http-builder-0.7.2.jar") ) but it did not work ( at least not from the script console. )

This is included in 3.0.x... presumably you are using an earlier version?

using Version: 3.0.5

well, it's there then...

I have the same problem... (Version: 3.0.12)

Actually I have the following error message:

java.lang.NullPointerException: Cannot invoke method addURL() on null object

when I would like to add the JAR file URL:

File myFile=new File("/Users/bdo/Workspace/Application/jira/jira_home/scripts/jconn2.jar");
URL myUrl = myFile.toURI().toURL();

Gives a solution or workaround for this case? For me it's not a good to copy my JAR file into the scriptrunner plugin lib folder, cause I can't update the Script Runner Add-On. 

Many thanks and regards,


You should use @Grab... there is much more to it than what you are doing. The classpath needs to be modified at the compile phase, the way you're doing it it's too late.
