在我的构建包中：
plugins {
kotlin("jvm") version "1.3.20"
id ("com.github.johnrengelman.shadow") version "4.0.3"
id ("com.devsoap.vaadin-flow") version "1.0"
id ("org.gretty") version "2.3.1"
}
val kotlinVersion = "1.3.20"
val jettyVersion = "9.4.14.v20181114"
val vaadinVersion = "12.0.4"
我有一个Vaadin项目，并由Gradle进行构建。 我通过pluggin shadowjar创建jar。 这是成功的构建项目。
在deploy文件夹中，我有：
folder: frontend
file: myproject.jar
file: logback.xml
要从控制台启动项目，请使用命令：
java -Dlogback.configurationFile=logback.xml -jar myproject.jar
好。开始成功了。
2019-03-13 10:36:35,747 3844 [main] INFO o.e.jetty.server.AbstractConnector - Started ServerConnector@22a79b2f{HTTP/1.1,[http/1.1]}{0.0.0.0:8080}
2019-03-13 10:36:35,747 3844 [main] INFO org.eclipse.jetty.server.Server - Started @4034ms
我成功打开了网页。
但是我需要设置生产模式。因此，我这样运行我的项目：
java -Dvaadin.productionMode=true -Dlogback.configurationFile=logback.xml -jar myproject.jar
它开始成功。但是当我尝试打开网页时出现错误：

java.lang.IllegalArgumentException: Failed to find the bundle manifest file 'frontend://vaadin-flow-bundle-manifest.json' in the servlet context for 'ES6' browsers. If you are running a dev-mode servlet container in maven e.g. `jetty:run` change it to `jetty:run-exploded`. If you are not compiling frontend resources, include the 'vaadin-maven-plugin' in your build script. Otherwise, you can skip this error either by disabling production mode, or by setting the servlet parameter 'original.frontend.resources=true'.
