在本地编译期间，如何在Quarkus maven插件中向GraalVM添加参数？

当我为应用程序构建本机映像时，出现了一些我不理解的错误。

    Error: unsupported features in 3 methods
    Detailed message:
    Error: com.oracle.svm.hosted.substitute.DeletedElementException:     Unsupported method java.lang.Class.getConstantPool() is reachable: The declaring class of this element has been substituted, but this element is not present in the substitution class

Graal建议我在运行时设置此选项--report-unsupported-elements-

我阅读了NativeImageMojo的代码

我正在尝试添加类似的内容：

  <plugin>
      <groupId>io.quarkus</groupId>
      <artifactId>quarkus-maven-plugin</artifactId>
      <version>${quarkus.version}</version>
      <executions>
      <execution>
          <goals>
             <goal>native-image</goal>
          </goals>
      <configuration>
           <enableHttpUrlHandler>true</enableHttpUrlHandler>
           <containerRuntimeOptions>--report-unsupported-elements-at-runtime</containerRuntimeOptions>
      </configuration>
      </execution>
      </executions>
  </plugin>

但是没有出现选项：

[INFO] [io.quarkus.creator.phase.nativeimage.NativeImagePhase] /sandbox/Resources/GraalVm/graalvm-ce-1.0.0-rc15/bin/native-image -J-Djava.util.logging.manager=org.jboss.logmanager.LogManager -J-Dcom.sun.xml.bind.v2.bytecode.ClassTailor.noOptimize=true -H:InitialCollectionPolicy=com.oracle.svm.core.genscavenge.CollectionPolicy$BySpaceAndTime -jar portfolio-app-1.0-SNAPSHOT-runner.jar -J-Djava.util.concurrent.ForkJoinPool.common.parallelism=1 -H:FallbackThreshold=0 -H:+PrintAnalysisCallTree -H:-AddAllCharsets -H:EnableURLProtocols=http,https --enable-all-security-services -H:NativeLinkerOption=-no-pie -H:-SpawnIsolates -H:+JNI --no-server -H:-UseServiceLoaderFeature -H:+StackTrace

如何在运行时添加--report-unsupported-elements-？ （我将Quarkus-bom 0.14.0与graalvm-ce-1.0.0-rc15一起使用）

您可以使用additionalBuildArgs参数：

<plugin>
  <groupId>io.quarkus</groupId>
  <artifactId>quarkus-maven-plugin</artifactId>
  <version>${quarkus.version}</version>
  <executions>
  <execution>
    <goals>
       <goal>native-image</goal>
    </goals>
  <configuration>
     <enableHttpUrlHandler>true</enableHttpUrlHandler>
     <additionalBuildArgs>--report-unsupported-elements-at-runtime</additionalBuildArgs>
  </configuration>
  </execution>
  </executions>
</plugin>

在这种情况下，最好的方法是使用：

import matplotlib.pyplot as plt
class test():
    def __init__(self):
        self.FIG, ax = plt.subplots()
    def abc(self, event):
        print("Yes")  
A = test()
A.FIG.canvas.mpl_connect("button_press_event",A.abc)
plt.show()

在配置本机图像目标时。

您的两个命题运作良好，但事实并非如此。
选项-H：+ ReportUnsupportedElementsAtRuntime返回：

我发现了一些documentation

  

-运行时报告不支持的元素报告在不访问映像的过程中第一次访问时在运行时报告不支持的方法和字段的使用情况。

我在此website

中找到有关-H：+ ReportUnsupportedElementsAtRuntime的信息
  

在运行时报告不支持的方法和字段的使用情况   第一次访问，而不是在图像处理期间出错   建筑

说明是完全一样的，但是我不明白为什么回报会有所不同。
