Karl Heinz Marbaise commented on MNG-6455:
------------------------------------------
Based on the given example you are using {{mvn install}} where [in the
documentation|https://maven.apache.org/maven-ci-friendly.html#install-deploy]
explicitly stated that if you use {{install/deploy}} you *have to* configure
the {{flatten-maven-plugin}} which is responsible to resolve the special
properties. Otherwise it will not work.
The example for {{parent-pom}} does not contain a configuration for
{{flatten-maven-plugin}} which will result in such issues.
If you have *not* configured {{flatten-maven-plugin}} you can take a look into
the installed {{parent-pom.xml}} which looks like this:
{code:xml}
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0
http://maven.apache.org/xsd/maven-4.0.0.xsd";>
<modelVersion>4.0.0</modelVersion>
<groupId>com.example</groupId>
<artifactId>parent-pom</artifactId>
<version>${revision}</version>
<packaging>pom</packaging>
<properties>
<revision>1.0.0-SNAPSHOT</revision>
</properties>
...
{code}
If you have configured {{flatten-maven-plugin}} the result in the
{{parent-pom.xml}} you have installed looks like this:
{code:xml}
<?xml version="1.0" encoding="UTF-8"?>
<project xsi:schemaLocation="http://maven.apache.org/POM/4.0.0
https://maven.apache.org/xsd/maven-4.0.0.xsd";
xmlns="http://maven.apache.org/POM/4.0.0";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";>
<modelVersion>4.0.0</modelVersion>
<groupId>com.example</groupId>
<artifactId>parent-pom</artifactId>
<version>1.0.0-SNAPSHOT</version>
<packaging>pom</packaging>
<properties>
<revision>1.0.0-SNAPSHOT</revision>
</properties>

> ci-friendly version in parent pom displays build warning in child project
> -------------------------------------------------------------------------
>
> Key: MNG-6455
> URL: https://issues.apache.org/jira/browse/MNG-6455
> Project: Maven
> Issue Type: Bug
> Reporter: Robert Thornton
> Priority: Minor
> Attachments: mng-6455.zip
>
>
> I have a project that is using a parent project with ci-friendly versions,
> but while Maven is scanning for projects, it is looking for
> "my-parent-$%7Brevision%7D.pom" instead of "my-parent-1.0-a8e435". The
> project builds, but a warning is printed which confuses some of the teams
> using my parent pom.
> {{[INFO] Scanning for projects...}}
> {{Downloading from mvn-lds:
> https://code.myserver.org/artifactory/mvn-repo/my/stack/platform/my-parent/$%7Brevision%7D/my-parent-$%7Brevision%7D.pom}}
> {{[WARNING] Failed to build parent project for
> my.stack.platform:my-project:pom:4.8.2.RELEASE}}
>
> I've tracked the issue down to DefaultProjectBuilder, line 671 where
> `project.getParentArtifact()` is returning an Artifact object with the
> unresolved version.
