使用 AWS lambda 的本机 Quarkus 无法构建

Question

我正在尝试使用 Quarkus 本机来构建我的 AWS Lambda。

我的设置是：

• GraalVM 19.3.0
• Java 11
• Ubuntu

当我跑步时

docker run -v /home/mypc/dev/java/quarkus/alexa_swear/target/<my project>-1.0-SNAPSHOT-native-image-source-jar:/project:z --user 1000:1000 --rm quay.io/quarkus/ubi-quarkus-native-image:19.2.1 -J-Djava.util.logging.manager=org.jboss.logmanager.LogManager --initialize-at-build-time= -H:InitialCollectionPolicy=com.oracle.svm.core.genscavenge.CollectionPolicy\$BySpaceAndTime -jar <my project>-1.0-SNAPSHOT-runner.jar -J-Djava.util.concurrent.ForkJoinPool.common.parallelism=1 -H:FallbackThreshold=0 -H:+ReportExceptionStackTraces -H:+AddAllCharsets -H:EnableURLProtocols=http -H:-JNI --no-server -H:-UseServiceLoaderFeature -H:+StackTrace <my project>-1.0-SNAPSHOT-runner

我收到以下错误：

Error: Image build request failed with exit status 1

上面的错误被截断：同一个调用栈指向不同的不支持的方法，比如java.lang.Thread.stop。

我的基本理解是io.quarkus.amazon.lambda.runtime.AmazonLambdaRecorder$2.run(AmazonLambdaRecorder.java是指一些不支持的方法，比如java.lang.Thread.resume()。 我也尝试过使用 Quarkus 19.2.1 失败。

以上命令由mvn clean install -Pnative -Dnative-image.docker-build=true -e执行。

我终于找到了问题的原因。

在我的代码的非工作版本中，我使用了com.amazon.ask.AlexaSkill 的工厂，它以某种方式注入到入口点中，如下所示：

package io.mirko.lambda;

import com.amazon.ask.AlexaSkill;
import com.amazon.ask.Skills;
import com.amazon.ask.dispatcher.request.handler.HandlerInput;
import com.amazon.ask.dispatcher.request.handler.RequestHandler;
import com.amazon.ask.model.RequestEnvelope;
import com.amazon.ask.model.ResponseEnvelope;
import com.amazon.ask.request.interceptor.GenericRequestInterceptor;
import io.mirko.lambda.handlers.*;

import javax.enterprise.context.ApplicationScoped;
import javax.enterprise.inject.Instance;
import javax.enterprise.inject.Produces;
import javax.inject.Inject;
import javax.inject.Named;
import java.util.*;
import java.util.stream.StreamSupport;


public class SkillFactory {
    @Inject
    Instance<RequestHandler> handlers;

    @Produces
    @ApplicationScoped
    @Named
    public AlexaSkill<RequestEnvelope, ResponseEnvelope> createSkill() {
        return Skills.standard()
                .addRequestHandlers(handlers.stream().toArray(RequestHandler[]::new))
                .addRequestInterceptor(new GenericRequestInterceptor<HandlerInput>() {
                    @Override
                    public void process(HandlerInput handlerInput) {
                        System.out.format("Processing %s\n", handlerInput.getRequest());
                    }
                })
                // Add your skill id below
                //.withSkillId("")
                .build();
    }
}

...

public class SwearStreamLambda extends SkillStreamHandler {
    @Named("swearStream")
        public SwearStreamLambda() {
            //noinspection unchecked
            super((AlexaSkill<RequestEnvelope, ResponseEnvelope>)
                getBean(new ParameterizedTypeImpl(AlexaSkill.class, RequestEnvelope.class, ResponseEnvelope.class)));

通过删除 SkillFactory 类并将其逻辑移到 SwearStreamLambda 类中，编译顺利进行。

一些注意事项：

1. 此问题与 CDI 无关，因为它在整个项目中大量使用
2. 该问题与项目其他部分中存在的@Produces 注释无关
3. 该问题与javax.enterprise.inject.Instance 无关，因为删除它并不能解决问题

总而言之，我找不到问题的根本原因，但我认为我的问题已解决。

附：通过构建以下内容可以消除原始问题：

mvn clean install -Pnative -Dnative-image.docker-build=true -Dquarkus.native.enable-jni=true

请参阅https://github.com/quarkusio/quarkus/issues/6395#issuecomment-570755587。

这并不能解决所有问题，因为必须配置 Quarkus 反射，但它解决了具体问题。
