如何在Quarkus maven插件中，我可以在本机编译期间向GraalVM添加参数？

Question

当我为我的应用程序构建本机映像时，我有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-不支持的-元素

我读了NativeImageMojo的密码

我想说的是：

  <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>

但选项不显示：

[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

我如何在运行时添加--report-unperding-entels-at-runtime？（我使用Quarkus-bom 0.14.0与graalvm-ce-1.0.0-rc15）

Answer 1

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>

你的两个命题工作得很好，但两者并不完全相同。
选项-H：报告不支持的元素运行时返回：

Error: Image build request failed with exit status 1

我找到一些留档

--运行时报告不支持的元素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，而不是作为映像构建期间的错误。

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

在第一次访问不受支持的方法和字段时，在运行时报告它们的使用情况，而不是在映像构建期间作为错误报告

描述完全相同，但我不明白为什么回报不同。

Answer 3

在这种情况下，最好的方法是使用：

<reportErrorsAtRuntime>true</reportErrorsAtRuntime>

在您的本机图像目标的配置中。
