Hi All,

After upgrading AEM 6.5 to Service Pack 6.5.23, one of our bundles is showing multiple OSGi import errors under /system/console/bundles.

The affected bundle:
Project – Google Captcha (.......platform. Captcha)

In the bundle status, I see many packages marked in red:

Cannot be resolved but is not required

Imported Packages:

com.google.appengine.api.datastore -- Cannot be resolved but is not required
com.google.appengine.api.memcache -- Cannot be resolved but is not required
com.google.appengine.api.urlfetch -- Cannot be resolved but is not required
com.google.auth from ...platform.captcha (598)
com.google.protobuf.nano -- Cannot be resolved but is not required
com.jcraft.jzlib -- Cannot be resolved but is not required
com.ning.compress -- Cannot be resolved but is not required
com.ning.compress.lzf -- Cannot be resolved but is not required

reactor.blockhound.integration -- Cannot be resolved but is not required
sun.misc -- Cannot be resolved but is not required and overwritten by Boot Delegation
sun.security.x509 -- Cannot be resolved but is not required and overwritten by Boot Delegation

Any help or recommended approach would be greatly appreciated.
Regards,
Nagendra

The good news is that most of these are marked as "Cannot be resolved but is not required" - meaning they're optional dependencies that won't prevent your bundle from functioning. Check if your reCAPTCHA functionality is actually working despite these warnings, your bundle may be functioning perfectly fine... of course, test your CAPTCHA implementation to confirm.

Then you can modify your bundle's pom.xml to mark these imports as optional explicitly:

<plugin>
    <groupId>org.apache.felix</groupId>
    <artifactId>maven-bundle-plugin</artifactId>
    <configuration>
        <instructions>
            <Import-Package>
                com.google.appengine.api.datastore;resolution:=optional,
                com.google.appengine.api.memcache;resolution:=optional,
                com.google.appengine.api.urlfetch;resolution:=optional,
                com.google.protobuf.nano;resolution:=optional,
                *
            </Import-Package>
            <Embed-Dependency>
                google-api-client,
                google-http-client,
                google-http-client-jackson2;
                inline=true
            </Embed-Dependency>
            <Import-Package>
                !com.google.appengine.*,
                !com.google.protobuf.nano,
                *
            </Import-Package>
        </instructions>
    </configuration>
</plugin>

The !com.google.appengine.* syntax explicitly excludes these packages from import requirements.

On the other hand, if during testing the reCAPTCHA functionality isn't working as expected and you need to embed any of those google packages you can have a look at here: maven-bundle-plugin or bnd-maven-plugin
