How to load a jira core api class dynamically?

Hello Atlassian Team,

I am unmarshaling a json string element containing the following fully qualified class name:


I am trying to obtain the Class object for this class using the following line of code


When I run this code, I am getting ClassNotFoundException. We then realized that the class was not getting loaded. In order to load the class, I had to run the following lines of code:



This line loaded the class and then I was able to obtain the Class object that I needed.

Now coming to the question.

Could you please tell me how to load the class using a classLoader (or something similar) when I want to generalize the above line of code as following:

Class.forName(name); // name is a string which receives a value at runtime.

Hello Jobin,

Thank you for your solutions. I was able to figure out the class in JIRA core API that can dynamically load classes given the name of the class as a string. The following code was able to load the class that I needed dynamically.

ClassLoaderUtils.loadClass(name, <this-class-name>.class.getClassLoader());

Are you trying to do this in a plugin? To make the core classes available, use the following maven dependency in the pom.


Yes Jobin. I have uncommented this dependency in pom.xml.

Still not seeeing it? Make sure you clean up the project and recreate it. And then refresh the IDE.

For ecllipse:

mvn elicpse:clean eclipse:eclipse

Hello Jobin,

Thank you for your solutions and support. I have found a class that can load classes that I need given the classname. The following code was able to load the classes that I need.


ClassLoaderUtils.loadClass(name, this.getClass().getClassLoader())

Where name is fully qualified classname as a string, this.getClass().getClassLoader() returns the class loader of the calling class.
