Research direction

Start by inspecting the POM's maven-bundle-plugin configuration and the generated MANIFEST.MF. Consolidate the Export-Package entries as described, then verify that feign.form, feign.form.multipart, and feign.form.util are exported and that FormEncoder is usable in an OSGi environment.

Written by the indexing model from the issue text.

Description

The current POM has the following:

<plugin>
  <groupId>org.apache.felix</groupId>
  <artifactId>maven-bundle-plugin</artifactId>
  <configuration>
    <instructions>
      <Export-Package>feign.form</Export-Package>
      <Export-Package>feign.form.multipart</Export-Package>
    </instructions>
  </configuration>
</plugin>

Unfortunately, Maven Bundle plugin (and the underlying BND library), only process the 'final' Export-Package command. So, the MANIFEST.MF that is generated has the wrong Export-Package:

Export-Package: feign.form.multipart;version="13.16.0";uses:="feign.codec"

By changing it to:

<plugin>
  <groupId>org.apache.felix</groupId>
  <artifactId>maven-bundle-plugin</artifactId>
  <configuration>
    <instructions>
      <Export-Package>feign.form,feign.form.*</Export-Package>
    </instructions>
  </configuration>
</plugin>

You end up with the correct MANIFEST.MF of:

Export-Package: feign.form;uses:="feign,feign.codec,feign.form.multipart";version="13.16.0",feign.form.multipart;version="13.16.0";uses:="feign .codec",feign.form.util;version="13.16.0"

Without this change, you can't add the FormEncoder to the Feign builder to add support for x-www-data-urlencoded within an OSGi environment, since FormEncoder is not exported.
