Vaadin 12.0.4
Maven 3+
I download simple project from Vaadin’s official site https://vaadin.com/start/latest/simple-ui
In my Vaadin Maven and Jetty project.
In my pom.xml
<profiles>
<profile>
<!-- Production mode can be activated with either property or profile -->
<id>production-mode</id>
<activation>
<property>
<name>vaadin.productionMode</name>
</property>
</activation>
<properties>
<vaadin.productionMode>true</vaadin.productionMode>
</properties>
<dependencies>
<dependency>
<groupId>com.vaadin</groupId>
<artifactId>flow-server-production-mode</artifactId>
</dependency>
</dependencies>
It’s success build and start in DEBUG mode. Nice.
But I want to start project in production mode.
I start from command line:
mvn jetty:run -Pproduction-mode
or like this
mvn jetty:run -Pproduction-mode -Dvaadin.productionMode=true
Project success started. But when I try to open web page (localhost:8080) I get error:
[WARNING]
unavailable
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'.
