How to bundle NetBeans Plugins with my App?

I'd like to bundle some editors that NB provides with my app, but it seems like a very difficult process.

In this example I tried adding a json-editor. I thought it should be as simple as adding the "org-netbeans-modules-javascript2-kit" to my application module:

Code:
        <dependency>
            <groupId>org.netbeans.modules</groupId>
            <artifactId>org-netbeans-modules-javascript2-kit</artifactId>
            <version>${netbeans.version}</version>
        </dependency>


Compiling it showed a missing dependency for "javax.script.ScriptEngine.freemarker", so I'm adding this one:

Code:
        <dependency>
            <groupId>org.netbeans.modules</groupId>
            <artifactId>org-netbeans-libs-freemarker</artifactId>
            <version>${netbeans.version}</version>
        </dependency>


(why isn't this a dependency on the org-netbeans-modules-javascript2-kit module by default?)

Now it compiles, but I get a startup issue:
"java.lang.IllegalStateException: No ActiveDocumentProvider instance in global lookup."
Googling this, I found this:
https://netbeans.org/bugzilla/show_bug.cgi?id=254949
which linked to this:
http://hg.netbeans.org/core-main/rev/2666c7e4b839
So I found maven modules for the added lines (thinking: this can't be the correct way to do this?):

Code:
         <dependency>
            <groupId>org.netbeans.api</groupId>
            <artifactId>org-netbeans-modules-editor-document</artifactId>
            <version>${netbeans.version}</version>
        </dependency>
        <dependency>
            <groupId>org.netbeans.api</groupId>
            <artifactId>org-netbeans-modules-parsing-api</artifactId>
            <version>${netbeans.version}</version>
        </dependency>
        <dependency>
            <groupId>org.netbeans.api</groupId>
            <artifactId>org-netbeans-modules-parsing-indexing</artifactId>
            <version>${netbeans.version}</version>
        </dependency>
        <dependency>
            <groupId>org.netbeans.modules</groupId>
            <artifactId>org-netbeans-modules-parsing-nb</artifactId>
            <version>${netbeans.version}</version>
        </dependency>
        <dependency>
            <groupId>org.netbeans.api</groupId>
            <artifactId>org-netbeans-modules-editor-indent-support</artifactId>
            <version>${netbeans.version}</version>
        </dependency>
        <dependency>
            <groupId>org.netbeans.api</groupId>
            <artifactId>org-netbeans-modules-editor-settings-lib</artifactId>
            <version>${netbeans.version}</version>
        </dependency>
        <dependency>
            <groupId>org.netbeans.modules</groupId>
            <artifactId>org-netbeans-modules-project-spi-intern</artifactId>
            <version>${netbeans.version}</version>
        </dependency>
        <dependency>
            <groupId>org.netbeans.api</groupId>
            <artifactId>org-netbeans-modules-projectuiapi-base</artifactId>
            <version>${netbeans.version}</version>
        </dependency>



Finally, my app starts up without errors, but when I open a json file, I get:
"A org.netbeans.modules.parsing.spi.ParseException exception has occurred."

Is it really necessary to go through this much trouble to get the json editor included?

The only (partially) working solution I found so far was to add the netbeans update centers to my app and then installing the javascript2-kit plugin from there.
Opening a json file worked with this, syntax errors where highlighted.. but for some weird reason, keyboard shortcuts like backspace for deleting the previous character have not been set.

Does anyone know of a better way of doing this? Is this maybe only so difficult when using maven projects instead of netbeans projects?
