当我为我的应用程序构建本机映像时，我遇到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 建议我设置此选项 --report-unsupported-elements-at-runtime

我阅读了NativeImageMojo的代码

我试图把类似的东西：

  <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>

但选项没有出现：

[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

如何添加 --report-unsupported-elements-at-runtime ？（我使用 Quarkus-bom 0.14.0 和 graalvm-ce-1.0.0-rc15）

在这种情况下，最好的方法是使用：

<reportErrorsAtRuntime>true</reportErrorsAtRuntime>

在您的 native-image 目标的配置中。

你的两个命题运作良好，但不完全一样。
选项 -H:+ReportUnsupportedElementsAtRuntime 返回：

Error: Image build request failed with exit status 1

我找到了一些文档

--report-unsupported-elements-at-runtime 在第一次访问时报告运行时不支持的方法和字段的使用情况，而不是在构建映像期间报告错误。

我在这个网站上找到了关于 -H:+ReportUnsupportedElementsAtRuntime 的信息

首次访问时在运行时报告不支持的方法和字段的使用情况，而不是在映像构建期间报告为错误

描述完全一样，但我不明白为什么返回不同。

您可以使用以下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>
