Hi,
if you build the repo with maven and then start one of the fat-jars (e.g. java -jar account-microservice-fat.jar -conf ../src/config/local.json) it lead to the following stacktrace.

The problem is that the generated-folders are not included in the fat-jar. What is best practice here?

java.lang.IllegalStateException: Cannot find proxyClass: io.vertx.blueprint.microservice.account.AccountServiceVertxProxyHandler at io.vertx.serviceproxy.ProxyHelper.loadClass(ProxyHelper.java:104) at io.vertx.serviceproxy.ProxyHelper.registerService(ProxyHelper.java:78) at io.vertx.serviceproxy.ProxyHelper.registerService(ProxyHelper.java:71) at io.vertx.serviceproxy.ProxyHelper.registerService(ProxyHelper.java:65) at io.vertx.blueprint.microservice.account.UserAccountVerticle.start(UserAccountVerticle.java:30) at io.vertx.core.impl.DeploymentManager.lambda$doDeploy$8(DeploymentManager.java:434) at io.vertx.core.impl.ContextImpl.lambda$wrapTask$2(ContextImpl.java:337) at io.netty.util.concurrent.AbstractEventExecutor.safeExecute(AbstractEventExecutor.java:163) at io.netty.util.concurrent.SingleThreadEventExecutor.runAllTasks(SingleThreadEventExecutor.java:403) at io.netty.channel.nio.NioEventLoop.run(NioEventLoop.java:445) at io.netty.util.concurrent.SingleThreadEventExecutor$5.run(SingleThreadEventExecutor.java:858) at java.lang.Thread.run(Thread.java:745) Caused by: java.lang.ClassNotFoundException: io.vertx.blueprint.microservice.account.AccountServiceVertxProxyHandler at java.net.URLClassLoader.findClass(URLClassLoader.java:381) at java.lang.ClassLoader.loadClass(ClassLoader.java:424) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:331) at java.lang.ClassLoader.loadClass(ClassLoader.java:357) at io.vertx.serviceproxy.ProxyHelper.loadClass(ProxyHelper.java:102) ... 11 more

Hi, I've reproduced this problem. This is related to the update of maven-compiler-plugin. Please downgrade the maven-compiler-plugin version from 3.6.1 to 3.1 temporarily (in pom.xml). I'll check the detailed changes of the plugin and update the configurations.
