DefaultMavenReaderFilter API does not correctly interpolate collection variables

[Simone Tripodi]

Hi all mates,

I am writing a plugin which needs to filter & then process resources,
I am using the DefaultMavenReaderFilter API below:

DefaultMavenReaderFilter#filter( Reader, boolean, MavenProject,
List<String>, boolean, MavenSession )

in my resource I declared few variables that have to be interpolated,
everything works except:

"license": "${project.licenses[0].name}"

which is not interpolated and keeps to be represented as the original
string; if I try to replace it with

"license": "${project.licenses}",

it is correctly interpolated as

"license":"[***@30135202]"

Any idea what is wrong?
Many thanks in advance!

I recognize the issue,  but never paid attention to it since in general it doesn't make sense to access any listing entry in the pom by index. I have no solution here.

correct ATM we don't really have interpolation in such scripted way :(

Thanks both for your kind reply, very appreciated!

I was sure Plexus Interpolator supported that so I had the trouble I
was doing something wrong at API level :)

Keep up the good work, all the best!

Hi Simone:

Please check if you can safely upgrade your plexus-interpolation
dependency, as support to interpolate on arrays/lists/maps was deleted at
some point, but then added again in version 1.24.

Regards,
Gabriel
