Error when run project

Fabio107 · December 4, 2019, 6:20pm

I download the Business App starter, and import in my intelij, so now I have 2 problems, first when I select the profile “production” and start the server I got the error (when I try to access the app):

HTTP ERROR 500
Problem accessing /. Reason:

    Server Error

Powered by Jetty:// 9.4.11.v20180605

and when I try to run the test (check the “it” profile) I got the error:(attached)

Hi Fabio, it looks to me that you’re running a quite old Jetty version, how did you get to that one ?

I think the business app starter should be using <jetty.version>9.4.15.v20190215</jetty.version> currently.

Can you test with the newer version and if it doesn’t work, please let us know the Java, Vaadin and Node.js version you have ?

Hi there. I have the same issue but I am using the adviced jetty version. Below is my full output:

I have the very same issue. Any suggestions here? It is only an issue in productionmode. Dev works fine.

Pekka3 · January 17, 2020, 3:38pm

Hi Peter. It looks to me the frontend bundle is not built at all, do you have the build-frontend goal enabled for vaadin-maven-plugin for the production build ? Like here https://github.com/vaadin/skeleton-starter-flow/blob/master/pom.xml#L180

Diego72 · January 17, 2020, 7:30pm

Hi, I have the same issue un Production Mode.

Thanks for reading!

Diego, I’m sad to hear that. I can see in the configuration that you are mixing compatibility mode (V10-13) related build goals into the mix (non-npm):

<goal>copy-production-files</goal>
<goal>package-for-production</goal>

You need to remove these. Then you should end up with this production profile (NOTE I changed the profile name to production):

        <profile>
            <!-- Production mode is activated using -Pproduction -->
            <id>production</id>
            <properties>
                <vaadin.productionMode>true</vaadin.productionMode>
            </properties>

            <dependencies>
                <dependency>
                    <groupId>com.vaadin</groupId>
                    <artifactId>flow-server-production-mode</artifactId>
                </dependency>
            </dependencies>

            <build>
                <plugins>
                    <plugin>
                        <groupId>com.vaadin</groupId>
                        <artifactId>vaadin-maven-plugin</artifactId>
                        <executions>
                            <execution>
                                <goals>
                                    <goal>build-frontend</goal>
                                </goals>
                            </execution>
                        </executions>
                    </plugin>
                </plugins>
            </build>
        </profile>

Also it is recommended that you have the prepare-frontend goal in the NOT-production mode profile for vaadin-maven-plugin:

    <build>
	    ...
        <plugins>
            <plugin>
                <groupId>com.vaadin</groupId>
                <artifactId>vaadin-maven-plugin</artifactId>
                <version>${vaadin.version}</version>
                <executions>
                    <execution>
                        <goals>
                            <goal>prepare-frontend</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>
