Flow

I download Vaadin Flow and Spring project from this link vaadin.com/start
and I have a problem in maven in that is, following code that can’t resolve and “vaadin.version” is 10.0.4



com.vaadin
vaadin-maven-plugin
${vaadin.version}

This works just fine for me:

	<dependencyManagement>
		<dependencies>
			<dependency>
				<groupId>com.vaadin</groupId>
				<artifactId>vaadin-bom</artifactId>
				<type>pom</type>
				<scope>import</scope>
				<version>${vaadin.version}</version>
			</dependency>
		</dependencies>
	</dependencyManagement>

	<dependencies>
		<dependency>
			<groupId>com.vaadin</groupId>
			<artifactId>vaadin-core</artifactId>
		</dependency>
