How to use for java 21+

Gradle

repositories {    maven {        url"https://gitlab.com/api/v4/projects/37512056/packages/maven"     }}ext {   rlibVersion="10.0.alpha6"}dependencies {  implementation"javasabr.rlib:rlib-common:$rlibVersion"  implementation"javasabr.rlib:rlib-collections:$rlibVersion"  implementation"javasabr.rlib:rlib-compiler:$rlibVersion"  implementation"javasabr.rlib:rlib-concurrent:$rlibVersion"  implementation"javasabr.rlib:rlib-geometry:$rlibVersion"  implementation"javasabr.rlib:rlib-logger-api:$rlibVersion"  implementation"javasabr.rlib:rlib-logger-slf4j:$rlibVersion"  implementation"javasabr.rlib:rlib-plugin-system:$rlibVersion"  implementation"javasabr.rlib:rlib-reference:$rlibVersion"  implementation"javasabr.rlib:rlib-reusable:$rlibVersion"  implementation"javasabr.rlib:rlib-fx:$rlibVersion"  implementation"javasabr.rlib:rlib-network:$rlibVersion"  implementation"javasabr.rlib:rlib-mail:$rlibVersion"  implementation"javasabr.rlib:rlib-testcontainers:$rlibVersion"}

Most interesting parts:

Fake SMTP Server

varcontainer =newFakeSMTPTestContainer()    .withSmtpPassword("pwd")    .withSmtpUser("test_user");container.start();container.waitForReadyState();// sending emails to this server// checking APIvarcount =container.getEmailCountFrom("from@test.com");// clearing APIcontainer.deleteEmails();

Classpath Scanner API

varscanner =ClassPathScannerFactory.newDefaultScanner();scanner.setUseSystemClasspath(true);scanner.scan();varimplementations =scanner.findImplements(Collection.class);varinherited =scanner.findInherited(AbstractArray.class);

Compiler API

varjavaSource =getClass().getResource("/java/source/TestCompileJavaSource.java");varcompiler =CompilerFactory.newDefaultCompiler();varcompiled =compiler.compile(javaSource.toURI());varinstance =ClassUtils.newInstance(compiled[0]);varmethod =instance    .getClass()    .getMethod("makeString");varresult =method.invoke(instance);

Logger API

// getting logger by class/namevarlogger =LoggerManager.getLogger(getClass());// global enable/disable debug levelLoggerLevel.DEBUG.setEnabled(true);logger.debug("Simple message");logger.debug(5, (val) ->"Lazy message with 5: " +val);logger.debug(5,"Lazy message with 5:%d"::formated);logger.debug(5,10D, (val1,val2) ->"Lazy message with 5: " +val1 +" and 10: " +val2);logger.debug(5,10D,"Lazy message with 5:%d and 10:%d"::formatted);// global disable debug levelLoggerLevel.DEBUG.setEnabled(false);// local enable debug level only for this logger instancelogger.setEnabled(LoggerLevel.DEBUG,true);

Mail Sender

varconfig =MailSenderConfig    .builder()    .from("from@test.com")    .host("smtp.test.com")    .port(smtpPort)    .password(smtpPassword)    .username(smtpUser)    .useAuth(true)    .enableTtls(true)    .sslHost("smtp.test.com")    .build();varjavaxConfig =JavaxMailSender.JavaxMailSenderConfig    .builder()    .executorKeepAlive(120)    .executorMaxThreads(20)    .executorMinThreads(1)    .build();varsender =newJavaxMailSender(config,javaxConfig);sender.send("to@test.com","Test Subject","Content");sender    .sendAsync("to@test.com","Test Subject","Content")    .thenAccept(aVoid ->System.out.println("done!"));

Network API

Simple String Echo Server/Client

varserverNetwork =NetworkFactory.newStringDataServerNetwork();varserverAddress =serverNetwork.start();serverNetwork    .accepted()    .flatMap(Connection::receivedEvents)    .subscribe(event -> {varmessage =event.packet.getData();System.out.println("Received from client: " +message);event.connection.send(newStringWritablePacket("Echo: " +message));    });varclientNetwork =NetworkFactory.newStringDataClientNetwork();clientNetwork    .connected(serverAddress)    .doOnNext(connection ->IntStream        .range(10,100)        .forEach(length ->connection.send(newStringWritablePacket(StringUtils.generate(length)))))    .flatMapMany(Connection::receivedEvents)    .subscribe(event ->System.out.println("Received from server: " +event.packet.getData()));
