Maven: Uncategorized problems with NetBeans dependency verification

Hi everybody,

I'm new to NB Platform and I can't figure out how to solve this:
I've been trying to add a new filetype using this tutorial:
https://platform.netbeans.org/tutorials/nbm-maven-modulesingle.html

At this point I was using RELEASE80 and got this error message:

> Failure to find org.netbeans.api:org-openide-util-ui:jar:RELEASE80 in http://bits.netbeans.org/nexus/content/groups/netbeans/ was cached in the local repository, resolution will not be reattempted until the update interval of netbeans has elapsed or updates are forced -> [Help 1]


I tried to autocomplete the version and noticed that the dependency was only available for RELEASE81.
So I changed to RELEASE81 and got a different error:


> Failed to execute goal org.codehaus.mojo:nbm-maven-plugin:4.1:manifest (default-manifest) on project My-View: Uncategorized problems with NetBeans dependency verification (maybe MNBMODULE-102 or wrong maven dependency metadata). Supposedly external classes are used in the project's binaries but the classes are not found on classpath.

After a bit of trial and error, I found that there seem to be conflicts between a dependency I have and two netbeans dependencies:


Code:

        <dependency>
            <groupId>org.netbeans.api</groupId>
            <artifactId>org-openide-util-ui</artifactId>
            <version>${netbeans.version}</version>
        </dependency>
        <dependency>
            <groupId>org.netbeans.api</groupId>
            <artifactId>org-netbeans-api-templates</artifactId>
            <version>${netbeans.version}</version>
        </dependency>
        <dependency>
            <groupId>com.badlogicgames.gdx</groupId>
            <artifactId>gdx-backend-lwjgl</artifactId>
            <version>${libgdx.version}</version>
        </dependency>




Removing lwjgl fixes the problem, but I kinda need it.
Tracking it further down brings me to this one:

Code:
    <dependency>
      <groupId>org.lwjgl.lwjgl</groupId>
      <artifactId>lwjgl_util</artifactId>
      <version>${lwjgl.version}</version>
    </dependency>



And that's where I lose the trail.. The pom looks like this:
http://central.maven.org/maven2/org/lwjgl/lwjgl/lwjgl_util/2.9.2/lwjgl_util-2.9.2.pom
There is only a dependency for the lwjgl core, but adding it works without problem. Just the lwjgl_util artifact is problematic.

Does anyone have any idea how to fix this?

The versions:

Code:

        <libgdx.version>1.9.1</libgdx.version>
        <lwjgl.version>2.9.2</lwjgl.version>



Thanks in advance.
