gephi-toolkit-0.9.2-all.jar couldn't be added into current netbeans' module project

[askua]

Dear Gephi Group,
I'm develping a netbeans module project that need use toolkit to draw a graph !
I only added open source code package org.gephi.toolkit.demos;
When I add gephi-toolkit-0.9.2.jar into my netbeans module project, I could successfully compile the project,

But I failed to run it,
the IDE told me: java.lang.ClassNotFoundException

Error Note:
java.lang.ClassNotFoundException: org.netbeans.modules.masterfs.watcher.Watcher@ModuleCL@1b5dab8b[com.ml.predict]:jar:file:/D:/JavaProjects/CIF-DL/build/cluster/modules/ext/gephi-toolkit-0.9.2-all.jar!/ not a subclass of org.netbeans.modules.masterfs.watcher.Watcher@ModuleCL@1f1c9b7a[org.netbeans.modules.masterfs]:jar:file:/E:/CIFLog/platform/modules/org-netbeans-modules-masterfs.jar!/

My IDE Environment has
jdk1.8.0_192，Netbeans 8.2, apache-maven-3.6.0

I didn't know how to solve it,
I recompile the gephi-toolkit.jar , but it doesn't work

What should I do?

Hi, you should load the toolkit as a standard Maven dependency instead of loading the JAR.

<dependency>
    <groupId>org.gephi</groupId>
    <artifactId>gephi-toolkit</artifactId>
    <version>0.10.1</version>
</dependency>
