adding amd64 shared

libs.binding=shared
amd64-Windows-msvc.libs.binding=shared

then adding amd64 static overrides

libs.binding=static
amd64-Windows-msvc.libs.binding=static

then adding x86 shared

x86-Windows-msvc.libs.binding=shared
libs.binding=shared
amd64-Windows-msvc.libs.binding=static

then finally adding x86 static

x86-Windows-msvc.libs.binding=static
libs.binding=static
amd64-Windows-msvc.libs.binding=static

I seem to have run into this problem (or a closely related one)

[Some edits made to obscure some things but the gist of all aspects remain intact]

Consider the following output:
[INFO] --- nar-maven-plugin:3.10.1:nar-unpack (default-nar-unpack) @ xyz ---
[INFO] Getting Nar dependencies
[INFO] Unpacking 2 dependencies to /home/mixed/target/nar
[INFO] + ranlib /home/mixed/target/nar/cache-0.0-SNAPSHOT-amd64-Linux-gcc-static/lib/amd64-Linux-gcc/static/libcache-0.0-SNAPSHOT.a

Given the following pom entry to try and force the issue:

  <dependencies>
      <dependency>
      <groupId>xyz</groupId>
      <artifactId>cache</artifactId>
      <version>0.0-SNAPSHOT</version>
      <type>nar</type>
      <classifier>amd64-Linux-gcc-shared</classifier>   <-----
      </dependency>
  </dependencies>

Why is NAR resolving to unpacking the STATIC version of libcache when there's a SHARED version in the maven repository produced via the following plugin config:

<libraries>
    <library>
        <type>shared</type>
   </library>                    
    <library>
        <type>static</type>
   </library>
</libraries>

Here's the debug output showing the resolution path:

Sure enough the nar.properties in the SHARED lib artifact looks as follows:

#NAR Properties for cache-0.0-SNAPSHOT
includes.type=local
output=cache-0.0-SNAPSHOT
nar.shared=cache\:nar\:${aol}-shared
nar.static=cache\:nar\:${aol}-static
nar.noarch=cache\:nar\:noarch
amd64-Linux-gcc.output=cache-0.0-SNAPSHOT
libs.binding=static
amd64-Linux-gcc.libs.binding=static

Any way to resolve this temporarily via Config or CLI options?
Of course by manually exploding the SHARED lib nar and changing the last two *.libs.binding entries to "shared", the xyz project is able to pick up the correct SHARED lib when the -shared classifier is specified in its pom.xml depedency section.
Without the classifier xyz pulls in the STATIC lib.

	//static lib is preferred over other remaining types; see #231
	narInfo.setBinding(aol, type);
	narInfo.setBinding(null, type);
