java - 将 Steelseries JAR 文件加载到 Swing 调色板

Question

我刚刚开始在我的一个项目中使用 NetBeans，我需要在 GUI 中使用一个仪表。我遇到了Steelseries看起来确实很有希望，并下载了这个 JAR 文件:

http://www.java2s.com/Code/Jar/s/DownloadSteelSeries3926jar.htm

我创建了一个 Java 项目，向其中添加了库，并添加了 Swing 调色板。 一些 bean，例如 Lightbulb、Led 和 TrafficLight 可以正常工作；但是当我选择仪表时，我收到此错误:

"Cannot load component class eu.hansolo.steelseries.extras.Radar from JAR file. The class itself was found, but there was a problem initializing it, e.g. due to an exception in static initializer, or failure in loading an additional class needed by the component class."

异常堆栈跟踪如下:

SteelSeries ，最初托管于 Kenai ，已移至GitHub 。该项目取决于Trident图书馆，如所见here并在 pom.xml .

Do you also know why the Steelseries library is missing those needed modules?

link您提到引用了预构建的 JAR 文件，每个文件都不包括看到的依赖 lib 目录 here或引用的工件引用 here 。您接下来采取的具体方法将取决于您的 software configuration management计划。
