Question

我有一个JavaFX项目，并希望使用GraalVM Java虚拟机和相关的Native-Image工具将其编译为Linux二进制文件。我正在使用GraalVM Java 11版本20.1.0，以及通过Maven添加的Native Image Maven插件来实现此目的。

<plugin>
    <groupId>com.oracle.substratevm</groupId>
    <artifactId>native-image-maven-plugin</artifactId>
    <version>19.2.1</version>
    <configuration>
        <mainClass>sample.NewMain</mainClass>
        <imageName>sample</imageName>
        <buildArgs>
            -H:ReflectionConfigurationFiles=/home/user/Documents/Projects/TestProject/src/main/java/sample/reflect-config.json -H:+ReportExceptionStackTraces
        </buildArgs>
    </configuration>
    <executions>
        <execution>
            <goals>
                <goal>native-image</goal>
            </goals>
            <phase>package</phase>
        </execution>
    </executions>
</plugin>

最初，我收到一条错误消息，指出Warning: Aborting stand-alone image build due to reflection use without configuration.我使用了本机映像跟踪代理生成用于反射的配置文件，我将其传递给编译器插件，如下所示： -H:ReflectionConfigurationFiles=/home/user/Documents/Projects/TestProject/src/main/java/sample/reflect-config.json -H:+ReportExceptionStackTraces

我还打开了堆栈跟踪异常报告。

现在，当我尝试编译为本机映像时，出现以下与本机库的使用有关的错误：

Warning: System method java.lang.System.loadLibrary invoked at com.sun.glass.utils.NativeLibLoader.loadLibraryInternal(NativeLibLoader.java:163)

如何配置本机库的使用？在本机图像编译器工具中，没有任何选择，也没有我能在任何地方找到的任何提及。

我设法使用Native Image工具编译了其他项目，这意味着此问题与JavaFX有关。

这种方式不起作用。为此，您将必须使用Gluons client-maven-plugin https://github.com/gluonhq/client-maven-plugin。它提供了经过编译的Java和JavaFX库的特殊版本来完成此工作。请严格按照说明进行操作。然后它将起作用。我会定期使用它。

如何使用GraalVM和JavaFX在Maven中编译本机映像？
