org.osgi.framework.BundleException:osgi.wiring.package=com.adobe.cq.sightly

Sometimes when we try to deploy code, bundles may not be in active state in AEM 6.1. We can see below error message.

Error Message:
22.07.2017 10:40:27.509 *ERROR* [qtp2141213534-59] org.apache.felix.http.jetty %bundles.pluginTitle: Cannot start (org.osgi.framework.BundleException: Unresolved constraint in bundle com.aem.kishore.bundle-core [463]: Unable to resolve 463.2: missing requirement [463.2] osgi.wiring.package; (&(osgi.wiring.package=com.adobe.cq.sightly)(version>=2.2.0)(!(version>=3.0.0))))

org.osgi.framework.BundleException: Unresolved constraint in bundle com.aem.kishore.bundle-core[463]: Unable to resolve 463.2: missing requirement [463.2] osgi.wiring.package; (&(osgi.wiring.package=com.adobe.cq.sightly)(version>=2.2.0)(!(version>=3.0.0)))



Solution:
Delete existing bundle first.
Add below code in bundle pom.xml and rebuild the code.

<Import-Package>

    !org.apache.log.*,

    !org.apache.avalon.*

        -----------------------------

        -----------------------------

 </Import-Package>

In AEM 6.1, it can be due to the unwanted "Equinox" bundle. Check this post for more info.
