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

             Summary: CI friendly properties break submodule builds
                 Key: MNG-6090
                 URL: https://issues.apache.org/jira/browse/MNG-6090
             Project: Maven
          Issue Type: Bug
          Components: core
    Affects Versions: 3.3.9
            Reporter: Harald Wellmann


h3. Scenario

A multi-module project where the parent version is one of the CI friendly properties, e.g. $\{revision\} as outlined in http://blog.soebes.de/blog/2016/08/08/maven-how-to-create-a-release/.

There are two submodules submodule1 and submodule2 such that submodule2 depends on submodule1.

h3. Expected behaviour

Each submodule can be built by itself, e.g.

{code}
mvn clean install -Drevision=1.0.0-SNAPSHOT -pl submodule2
{code}

or

{code}
cd submodule2; mvn clean install -Drevision=1.0.0-SNAPSHOT
{code}

h3. Actual behaviour

This does not work for submodule2 or in general any module that depends on a module from the same reactor.

Maven cannot resolve the property variable in the referenced parent POM version and fails the build:

{code}
[ERROR] Failed to execute goal on project submodule2: Could not resolve dependencies for project com.example:submodule2:jar:1.0.0-SNAPSHOT: Failed to collect dependencies at com.example:submodule1:jar:1.0.0-SNAPSHOT: Failed to read artifact descriptor for com.example:submodule1:jar:1.0.0-SNAPSHOT: Could not find artifact com.exammple:parent:pom:${revision} -> [Help 1]
{code}
 
There is no problem building submodule1 or the entire reactor.

Same problem observed with a local build from master (3.4.0-SNAPSHOT).
