问题

在编译JOGL代码时，我遇到了以下错误：

> 找不到 com.jogamp.common.type.WriteCloneable 的类文件

我还附上了错误的屏幕截图：

以下是代码：

    @Override    
    public void display(GLAutoDrawable drawable) {    
        final GL2 gl = drawable.getGL().getGL2();

你需要在编译您的类时包含[gluegen-rt库](https://jogamp.org/deployment/archive/rc/v2.4.0-rc-20200307/jar/gluegen-rt.jar)。

此外，您不需要解压缩jar文件。

使用`-cp`变量将一个jar库添加到您的[类路径](https://docs.oracle.com/javase/8/docs/technotes/tools/unix/classpath.html)：

```shell
javac -cp .:gluegen-rt.jar:jogl-all.jar HelloWorld.java

要运行您的示例，您还需要本机扩展。您可以在此处找到它们。

注意：特别是在使用最新的Mac OS版本时，请使用最新的JOGL库。

java -cp .:gluegen-rt.jar:jogl-all-natives-macosx-universal.jar:jogl-all.jar:gluegen-rt-natives-macosx-universal.jar HelloWorld

这是输出：

You need to include [gluegen-rt lib](https://jogamp.org/deployment/archive/rc/v2.4.0-rc-20200307/jar/gluegen-rt.jar) to compile your class.
Also, you don&#39;t need to unzip jar files.
Use `-cp` variable to add a jar library to your [classpath](https://docs.oracle.com/javase/8/docs/technotes/tools/unix/classpath.html):

javac -cp .:gluegen-rt.jar:jogl-all.jar HelloWorld.java

To run your example you also need native extensions. You can find them [here](https://jogamp.org/deployment/archive/rc/v2.4.0-rc-20200307/jar/) 
**Note**: Use the latest JOGL libraries especially if you use the latest Mac OS version.

java -cp .:gluegen-rt.jar:jogl-all-natives-macosx-universal.jar:jogl-all.jar:gluegen-rt-natives-macosx-universal.jar HelloWorld

Here is the output:

下载 jogamp-fat.jar 文件 [这里][1]（这是2020年10月的最新发行候选版本，否则，请在 JOGL 2.4.0 或以后的版本发布时使用 [这个][2]，通常情况下会更近一些）。
编译使用以下命令：
```shell
javac -cp .:jogamp-fat.jar HelloWorld.java

运行使用以下命令：

java -cp .:jogamp-fat.jar HelloWorld

你可以在我们的官方维基 这里 找到更多信息。Windows 用户需要将 : 替换为 ;。使用这个大型 JAR 文件更容易且对新手来说错误更少，它包含了所有 JogAmp API（JOGL、JOCL、JOAL 和 GlueGen）的 Java 库和本地库。

javac -cp .:jogamp-fat.jar HelloWorld.java

java -cp .:jogamp-fat.jar HelloWorld
