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

The intention was exactly to have the output does *not* contain a line ending cause it makes usage in scripts easier like:
{noformat}
RESULT=$(mvn -N -q org.apache.maven.plugins:maven-help-plugin:3.1.0:evaluate -Dexpression='project.groupId' -DforceStdout=true)
{noformat}
If it would contain a line ending this had meant you have to strip the line feed in situations like the above..
In the current implementation you can simply use it:
{noformat}
echo $RESULT
{noformat}
Apart from that Can you explain what you are trying to achieve ? Do you have an example pom which shows the above results? The output {{Picked up _JAVA_OPTIONS}} is only known to me inside Jenkins which is done by the pipeline spy integration....

>             Project: Maven Help Plugin
>          Issue Type: Improvement
>            Reporter: Patrick van Rhijn
>            Priority: Major
>
> When you use the plugin the output doesn't contain a line-ending making the output hard to use in scripting when you have JAVA_OPTIONS defined.
> In the current situation the plugin gives me the following output: 
> $ mvn -N -q org.apache.maven.plugins:maven-help-plugin:3.1.0:evaluate -Dexpression='project.groupId' -DforceStdout=true
> *nl.foo.barPicked up _JAVA_OPTIONS: -XX:+ForceTimeHighResolution -Dsun.java2d.noddraw=true -Duser.timezone='Europe/Amsterdam'*
> It would be better if the output would be divided over two lines and look like the output of the exec-maven-plugin:
> $ mvn -N -q -Dexec.executable='echo' -Dexec.args='${project.groupId}' org.codehaus.mojo:exec-maven-plugin:1.4.0:exec
> *nl.foo.bar*
> *Picked up _JAVA_OPTIONS: -XX:+ForceTimeHighResolution -Dsun.java2d.noddraw=true -Duser.timezone='Europe/Amsterdam'*
