NoClassDefFoundError con la clase FieldSecurityManager del plugin Field Security for Jira

Good afternoon community.

I am currently working with the Field Security for Jira plugin from the Atlassian market place and I am presenting the following error: java.lang.NoClassDefFoundError: com/quisapps/jira/fieldsecurity/schema/FieldSecurityManager

The problem arises because we are upgrading our services and the provider of this plugin asks us as a recommendation to update to its version 2.0.13, of which we previously had version 1.4.69_820.
For which in said old version, we used a particular class called FieldSecurityManager and tried to access it as follows (Package: com.quisapps.jira.fieldsecurity.scheme):

But now in this new version this class is not found in said package.

Therefore, I proceeded to decompile the .jar to give it further analysis and see if due to its update perhaps they changed the class to another package or perhaps the class was now called differently. But I find that the .jar, inside it has a .zip file called lib.zip.

When I review it, I see that inside you have more .jar files, of which there is one called jfs-core-2.0.13 and in this the file is located, although with a different name but with the methods that I need.

Now my question and what I ask you to support me with is if you know any way to how can I access the class? o What do you recommend I do to use this class? Because as I mentioned, it is located inside a .zip and at the same time inside another .jar.

I thank you in advance for your support.

I attach an image with screenshots of what was mentioned:

Hello @MoseleyDiegoGarcaBla

I don’t think anyone here can advise you on how or why to alter the Java classes of that company’s plugin. Those are the sort of questions that have to be raised directly with Quisapps. There is information on how to raising a support request, right there in the error message:

Untitled2

Also, your question is tagged with Jira Server, but the final version of that plugin made for that platform was v2.0.11 for Jira Server v8.0.0 - v9.8.2, yet you said ‘they’ asked you to upgrade to v2.0.13… but that is for Jira DATA CENTER v9.12

Hi @sunnyape

Indeed it was my mistake to place the tag as Jira Server. Now I have proceeded to change it to Jira Data Center. Thanks for the observation.

Also tell you that we have generated a ticket to the support team, but we wanted to look for alternatives in parallel to shorten times and move forward with our upgrade.

The issue here is that the quisapps team currently does not have documentation about its changes based on its versions and the official quisapps website, it is completely down and has been in this state for several days.

That is why I wanted to ask the community if they knew of any way to access said class despite being inside a .zip.

Greetings,
Diego Garcia.
