---------------------------------------

We were able to workaround this with [Maven Flatten Plugin|http://www.mojohaus.org/flatten-maven-plugin/flatten-mojo.html].

>             Project: Maven
>          Issue Type: Bug
>    Affects Versions: 3.5.0

> Consider simple multi-module project (see [^sources.tar.gz]):
> {noformat}
> parent/pom.xml
> parent/module-a
> parent/module-b
> {noformat}
> {{parent}} has defined project version via property {{revision}}:
> {code:xml}
>   <version>${revision}</version>
>   
>   <properties>
>     <revision>1.0.0-SNAPSHOT</revision>
>   </properties>
> {code} 
> Both sub-modules ({{module-a}} and {{module-b}}) define parent versions via this property:
> {code:xml}
>   <parent>
>     <groupId>test</groupId>
>     <artifactId>parent</artifactId>
>     <version>${revision}</version>
>   </parent>
> {code}
> Sub-module {{module-b}} has a dependency to {{module-a}}:
> {code:xml}
>   <dependency>
>       <groupId>test</groupId>
>       <artifactId>module-a</artifactId>
>       <version>${project.version}</version>
>     </dependency>
> {code}
> The project is built successfully from the root (see [^clean-install-root.log] for build log).
> Also there is no problem to build {{module-a}} independently (i.e. {{cd module-a && mvn clean install}}).
> But when trying to build {{module-b}} (i.e. {{cd module-b && mvn clean install}}), build fails (see [^clean-install-submodule.log]):
> {noformat}
> [ERROR] Failed to execute goal on project module-b: Could not resolve dependencies for project test:module-b:jar:1.0.0-SNAPSHOT: Failed to collect dependencies at test:module-a:jar:1.0.0-SNAPSHOT: Failed to read artifact descriptor for test:module-a:jar:1.0.0-SNAPSHOT: Could not find artifact test:parent:pom:${revision} in central (https://repo.maven.apache.org/maven2) -> [Help 1]
> {noformat} 
> Changing {{$\{project.version\}}} directly to {{$\{revision\}}} produces the same output.
