How to use GraalVM with JavaFX to compile a native image in Maven?
问题
我有一个JavaFX项目，想要使用GraalVM Java虚拟机和相关的Native-Image工具将其编译成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插件来实现这一目标。
以下是Maven插件的配置代码：
<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，我遇到了一个错误，错误信息为“Warning: Aborting stand-alone image build due to reflection use without configuration.” 我使用了Native Image追踪代理来生成反射的配置文件，并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
我还开启了堆栈跟踪异常报告功能。
然而，当我尝试编译成本地镜像时，我遇到了以下与本地库使用有关的错误：
Warning: System method java.lang.System.loadLibrary invoked at com.sun.glass.utils.NativeLibLoader.loadLibraryInternal(NativeLibLoader.java:163)Warning: System method java.lang.System.loadLibrary invoked at com.sun.glass.utils.NativeLibLoader.loadLibraryInternal(NativeLibLoader.java:177)Warning: Aborting stand-alone image build due to loading native libraries without configuration.com.oracle.svm.hosted.FallbackFeature$FallbackImageRequest: System method java.lang.System.loadLibrary invoked at com.sun.glass.utils.NativeLibLoader.loadLibraryInternal(NativeLibLoader.java:163)System method java.lang.System.loadLibrary invoked at com.sun.glass.utils.NativeLibLoader.loadLibraryInternal(NativeLibLoader.java:177)Aborting stand-alone image build due to loading native libraries without configuration.at com.oracle.svm.hosted.FallbackFeature.afterAnalysis(FallbackFeature.java:293)...
如何配置使用本地库？在Native Image编译工具中没有相应的选项，也没有我可以找到的任何相关提及。我已经成功地使用Native Image工具编译了其他项目，这意味着这个问题与JavaFX有关。
英文:
I have a JavaFX project, and would like to compile it into a Linux binary using the GraalVM Java virtual machine and the associated Native-Image tool. I am using GraalVM Java 11 Version 20.1.0, and the Native Image Maven plugin, that is added through Maven, to achieve this.
<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>
Originally, I got an error stating Warning: Aborting stand-alone image build due to reflection use without configuration. I used the Native Image tracing agent to generate config files for reflection,
which I pass into the compiler plugin like this:
-H:ReflectionConfigurationFiles=/home/user/Documents/Projects/TestProject/src/main/java/sample/reflect-config.json -H:+ReportExceptionStackTraces
I also have stack trace exception reporting turned on.
Now, when I attempt to compile to a native image, I get the following error to do with the usage of native libraries:
Warning: System method java.lang.System.loadLibrary invoked at com.sun.glass.utils.NativeLibLoader.loadLibraryInternal(NativeLibLoader.java:163)Warning: System method java.lang.System.loadLibrary invoked at com.sun.glass.utils.NativeLibLoader.loadLibraryInternal(NativeLibLoader.java:177)Warning: Aborting stand-alone image build due to loading native libraries without configuration.com.oracle.svm.hosted.FallbackFeature$FallbackImageRequest: System method java.lang.System.loadLibrary invoked at com.sun.glass.utils.NativeLibLoader.loadLibraryInternal(NativeLibLoader.java:163)System method java.lang.System.loadLibrary invoked at com.sun.glass.utils.NativeLibLoader.loadLibraryInternal(NativeLibLoader.java:177)Aborting stand-alone image build due to loading native libraries without configuration.at com.oracle.svm.hosted.FallbackFeature.afterAnalysis(FallbackFeature.java:293)at com.oracle.svm.hosted.NativeImageGenerator.lambda$runPointsToAnalysis$9(NativeImageGenerator.java:741)at com.oracle.svm.hosted.FeatureHandler.forEachFeature(FeatureHandler.java:70)at com.oracle.svm.hosted.NativeImageGenerator.runPointsToAnalysis(NativeImageGenerator.java:741)at com.oracle.svm.hosted.NativeImageGenerator.doRun(NativeImageGenerator.java:538)at com.oracle.svm.hosted.NativeImageGenerator.lambda$run$0(NativeImageGenerator.java:451)at java.base/java.util.concurrent.ForkJoinTask$AdaptedRunnableAction.exec(ForkJoinTask.java:1407)at java.base/java.util.concurrent.ForkJoinTask.doExec(ForkJoinTask.java:290)at java.base/java.util.concurrent.ForkJoinPool$WorkQueue.topLevelExec(ForkJoinPool.java:1020)at java.base/java.util.concurrent.ForkJoinPool.scan(ForkJoinPool.java:1656)at java.base/java.util.concurrent.ForkJoinPool.runWorker(ForkJoinPool.java:1594)at java.base/java.util.concurrent.ForkJoinWorkerThread.run(ForkJoinWorkerThread.java:177)
How can I configure the use of native libraries? There is no option for this within the Native Image compiler tool, nor any mention of it that I can find anywhere.
I have managed to compile other projects with the Native Image tool, which means that this problem is JavaFX related.

这样不起作用。 您将需要使用Gluon的client-maven-plugin（https://github.com/gluonhq/client-maven-plugin）来实现此目的。 它提供了编译的Java和JavaFX库的特殊版本，以使此工作正常。 请仔细按照说明操作。 然后它将正常工作。 我经常在使用它。

This does not work that way. You will have to use Gluons client-maven-plugin https://github.com/gluonhq/client-maven-plugin for this purpose. It provides a special version of compiled Java and JavaFX libraries to make this work. Follow the instructions closely. Then it will work. I am using it on a regular basis.
