Quarkus

“mvn package -Pnative” builds the native image from quarkus project. Important step is we have to run that mvn command from “native tools commnad” of visual studio. If you run the command from regular command prompt you get the error below [INFO] [io.quarkus.deployment.pkg.steps.NativeImageBuildRunner] C:\Program Files\GraalVM\graalvm-ce-java17-21.3.0\bin\native-image.cmd -J-Djava.util.logging.manager=org.jboss.logmanager.LogManager -J-Dsun.nio.ch.maxUpdateArraySize=100 -J-Dvertx.logger-delegate-factory-class-name=io.quarkus.vertx.core.runtime.VertxLogDelegateFactory -J-Dvertx.disableDnsResolver=true -J-Dio.netty.leakDetection.level=DISABLED -J-Dio.netty.allocator.maxOrder=3 -J-Duser.language=en -J-Duser.country=US -J-Dfile.encoding=UTF-8 -H:InitialCollectionPolicy=com.oracle.svm.core.genscavenge.CollectionPolicy\$BySpaceAndTime -H:+JNI -H:+AllowFoldMethods -H:FallbackThreshold=0 -H:+ReportExceptionStackTraces -H:-AddAllCharsets -H:EnableURLProtocols=http -H:-UseServiceLoaderFeature -H:+StackTrace chinese-lang-1.0.0-SNAPSHOT-runner -jar chinese-lang-1.0.0-SNAPSHOT-runner.jar [chinese-lang-1.0.0-SNAPSHOT-runner:6432] classlist: 5,366.54 ms, 0.96 GB [chinese-lang-1.0.0-SNAPSHOT-runner:6432] setup: 943.11 ms, 0.96 GB Error: Default native-compiler executable 'cl.exe' not found via environment variable PATH Error: To prevent native-toolchain checking provide command-line option -H:-CheckToolchain com.oracle.svm.core.util.UserError$UserException: Default native-compiler executable 'cl.exe' not found via environment variable PATH To prevent native-toolchain checking provide command-line option -H:-CheckToolchain at com.oracle.svm.core.util.UserError.abort(UserError.java:144) at com.oracle.svm.hosted.c.codegen.CCompilerInvoker.addSkipCheckingInfo(CCompilerInvoker.java:104) at com.oracle.svm.hosted.c.codegen.CCompilerInvoker.<init>(CCompilerInvoker.java:72) at com.oracle.svm.hosted.c.codegen.CCompilerInvoker$WindowsCCompilerInvoker.<init>(CCompilerInvoker.java:110) at com.oracle.svm.hosted.c.codegen.CCompilerInvoker.create(CCompilerInvoker.java:84) at com.oracle.svm.hosted.NativeImageGenerator.setupNativeImage(NativeImageGenerator.java:864) at com.oracle.svm.hosted.NativeImageGenerator.doRun(NativeImageGenerator.java:527) at com.oracle.svm.hosted.NativeImageGenerator.run(NativeImageGenerator.java:488) at com.oracle.svm.hosted.NativeImageGeneratorRunner.buildImage(NativeImageGeneratorRunner.java:403) at com.oracle.svm.hosted.NativeImageGeneratorRunner.build(NativeImageGeneratorRunner.java:569) at com.oracle.svm.hosted.NativeImageGeneratorRunner.main(NativeImageGeneratorRunner.java:122) at com.oracle.svm.hosted.NativeImageGeneratorRunner$JDK9Plus.main(NativeImageGeneratorRunner.java:599) [chinese-lang-1.0.0-SNAPSHOT-runner:6432] [total]: 6,384.40 ms, 0.96 GB # Printing build artifacts to: C:\Users\ozkan\projects\chinese-lang\target\chinese-lang-1.0.0-SNAPSHOT-native-image-source-jar\chinese-lang-1.0.0-SNAPSHOT-runner.build_artifacts.txt Error: Image build request failed with exit status 1 [INFO] ------------------------------------------------------------------------ [INFO] BUILD FAILURE [INFO] ------------------------------------------------------------------------ [INFO] Total time: 22.552 s [INFO] Finished at: 2021-11-03T21:07:37Z [INFO] ------------------------------------------------------------------------ [ERROR] Failed to execute goal io.quarkus.platform:quarkus-maven-plugin:2.4.1.Final:build (default) on project chinese-lang: Failed to build quarkus application: io.quarkus.builder.BuildException: Build failure: Build failed due to errors [ERROR] [error]: Build step io.quarkus.deployment.pkg.steps.NativeImageBuildStep#build threw an exception: java.lang.RuntimeException: Failed to build native image [ERROR] at io.quarkus.deployment.pkg.steps.NativeImageBuildStep.build(NativeImageBuildStep.java:233) [ERROR] at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke0(Native Method) [ERROR] at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:77) [ERROR] at java.base/jdk.internal.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) [ERROR] at java.base/java.lang.reflect.Method.invoke(Method.java:568) [ERROR] at io.quarkus.deployment.ExtensionLoader$2.execute(ExtensionLoader.java:821) [ERROR] at io.quarkus.builder.BuildContext.run(BuildContext.java:277) [ERROR] at org.jboss.threads.ContextHandler$1.runWith(ContextHandler.java:18) [ERROR] at org.jboss.threads.EnhancedQueueExecutor$Task.run(EnhancedQueueExecutor.java:2449) [ERROR] at org.jboss.threads.EnhancedQueueExecutor$ThreadBody.run(EnhancedQueueExecutor.java:1478) [ERROR] at java.base/java.lang.Thread.run(Thread.java:833) [ERROR] at org.jboss.threads.JBossThread.run(JBossThread.java:501) [ERROR] Caused by: java.lang.RuntimeException: Image generation failed.

I set up this almost 1 year ago. And then I decided to add GO to this competition. And here it is a screen shot of HAProxy, it has been working for 350 days. looks like GO is the clear winner here in this list :) you can see the code of quarkus and go here

I was trying to use freemarker with quarkus and vertx. I start getting this error Could not find MessageBodyWriter for response object of type: io.vertx.reactivex.core.buffer.Buffer of media type: text/html;charset=UTF-8 And code look like below. I was trying to use reactive approach. @GET @Produces(MediaType.TEXT_HTML) public Uni<Object> doSomethingAsync() throws Exception { io.vertx.core.Vertx params = vertx.getDelegate(); io.vertx.reactivex.core.Vertx args = new io.vertx.reactivex.core.Vertx(params); FreeMarkerTemplateEngine engine = FreeMarkerTemplateEngine.create(args); List<ExampleObject> exs = new ArrayList<>(); for (int i = 0; i < 10; i++) { exs.add(new ExampleObject("name:" + i, "dev:" + i)); } HashMap data = new HashMap<>(); data.put("title", "Vert.x Web"); data.put("exampleObject", new ExampleObject("name", "dev")); data.put("systems", exs); Single<Buffer> rxRender = engine.rxRender(data, "/templates/index.htm"); Buffer page = null; try { page = rxRender.toFuture().get(); } catch (Exception ex) { ex.printStackTrace(); // e.printStacktrace(); } return Uni.createFrom().item(page); } I check and could not find a proper solution here is how I solved it. ...

I have been using springboot remote command runner from ozkanpakdil/CommandRunner around 2 years. And last week I had a chance to play with quarkus. And I really like the startup time and speed of development is two times faster. So I decided to write same command runner with quarkus and see how it works. ozkanpakdil/quarkus-command-runner Only difference is in spring I used hazelcast and in quarkus I used ehcache. Because hazelcast configuration was not easy as in spring-boot. Then I decided to install haproxy and run these 2 microservices behind it. You can see the configuration here I must say the “command” running at linux side sometimes takes longer then 60 seconds so I gave haproxy longer timeout instructions. here is the haproxy admin ...
