Subject [jira] [Commented] (MINVOKER-194) wrong maven.compiler.source value in pom interpolation when run with Maven 3.3.x

Hervé Boutemy commented on MINVOKER-194:
----------------------------------------

I executed the MPIR IT with -X enabled and found a difference in invoker invocation between
Maven 3.2.5:
{noformat}[DEBUG] Executing: /bin/sh -c cd /tmp/maven-project-info-reports-plugin/target/it/java-version
&& /local/maven/apache-maven-3.2.5/bin/mvn -B -X -D maven.repo.local=/tmp/maven-project-info-reports-plugin/target/local-repo
-s /tmp/maven-project-info-reports-plugin/target/it/interpolated-settings.xml org.apache.maven.plugins:maven-project-info-reports-plugin:2.8.1-SNAPSHOT:summary
help:effective-pom -Doutput=effective-poms.xml{noformat}
and Maven 3.3.3:
{noformat}[DEBUG] Executing: /bin/sh -c cd /tmp/maven-project-info-reports-plugin/target/it/java-version
&& /local/apache-maven-3.3.3/bin/mvn -B -X -D maven.repo.local=/tmp/maven-project-info-reports-plugin/target/local-repo
-s /tmp/maven-project-info-reports-plugin/target/it/interpolated-settings.xml -D maven.compiler.source=1.5
-D maven.compiler.target=1.5 org.apache.maven.plugins:maven-project-info-reports-plugin:2.8.1-SNAPSHOT:summary
help:effective-pom -Doutput=effective-poms.xml{noformat}

I don't know why these {{-D maven.compiler.source=1.5 -D maven.compiler.target=1.5}} options
are added, but with these, model interpolation http://maven.apache.org/ref/3-LATEST/maven-model-builder/
prefers CLI over POM properties, then the result is consistent with the options

now we need to understand why these options are defined with Maven 3.3.x only

>             Project: Maven Invoker Plugin
>          Issue Type: Bug
>    Affects Versions: 1.8, 2.0.0
>            Reporter: Hervé Boutemy
>
> when working on MPIR, I found that java-version IT failed when build run with with Maven
3.3.x, but not when run with Maven 3.2.x or less
> I found that
> {code:xml}  <properties>
>     <maven.compiler.source>1.3</maven.compiler.source>
>     <maven.compiler.target>${maven.compiler.source}</maven.compiler.target>
>   </properties>{code}
> is interpolated to
> {code:xml}  <properties>
>     <maven.compiler.source>1.3</maven.compiler.source>
>     <maven.compiler.target>1.5</maven.compiler.target>
>   </properties>{code}
> when the IT is run with Maven 3.3.x
> but when the IT project is not run through invoker, there is no such interpolation value
issue, so I suppose m-invoker-p has some role when used in conjunction with Maven 3.3.x
