I am still struggling with the order:
https://maven.apache.org/ref/3.3.3/maven-model-builder/xref/org/apache/maven/model/interpolation/AbstractStringBasedModelInterpolator.html#L130.
What is supposed to take precedence?
Update: According to
https://maven.apache.org/ref/3.8.2/maven-model-builder/#Model_Interpolation it
is (for all variables not having prefix project., maven. or pom.)
# pom content
# user properties set via CLI argument {{-D}}
# model properties
# System properties
# environment variables

> Key: MNG-7222

> Project: Maven
> Issue Type: Improvement
> Components: Core
> Reporter: Konrad Windszus
> Priority: Major
>
> As properties referenced via {{${x}}} are first being resolved against system
> properties and only afterwards against Maven properties according to
> https://maven.apache.org/pom.html#properties. As this is often not noticed
> such collisions should be detected by Maven and lead to a WARN.
> An example for such a collision can be seen at
> https://github.com/adobe/aem-core-wcm-components/blob/6a294b0483c711a0283474f962a4643234e47c6e/parent/pom.xml#L64
> which is never effective as this is always overridden by
> https://docs.oracle.com/javase/tutorial/essential/environment/sysprop.html
> At least the mandatory properties (available on all JREs) outlined at
> https://docs.oracle.com/javase/8/docs/api/java/lang/System.html#getProperties--
> should always lead to a WARN.
