Major magnolia_main and magnolia_ui modules have different lifecycle - hence we have to use two separate properties for those versions in our poms:
<magnoliaVersion>5.0-SNAPSHOT</magnoliaVersion>
<magnoliaUiVersion>5.0-SNAPSHOT</magnoliaUiVersion>
Workflow pom currently only defines the first of these properties but uses it as version for ui modules - that's wrong:
<dependency>
<groupId>info.magnolia</groupId>
<artifactId>magnolia-core</artifactId>
<version>${magnoliaVersion}</version>
</dependency>
<dependency>
<groupId>info.magnolia.ui</groupId>
<artifactId>magnolia-ui-model</artifactId>
<version>${magnoliaVersion}</version>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>info.magnolia.ui</groupId>
<artifactId>magnolia-ui-admincentral</artifactId>
<version>${magnoliaVersion}</version>
<scope>provided</scope>
</dependency>
