Macro cannot be cast error

Example: I'm using v 2.0.7 or 2.0.x of the plugin, but it is not accepting my license.

Errors

“Error rendering macro ‘multiexcerpt-include’: com.atlassian.upm.license.internal.impl.PluginLicenseManagerImpl cannot be cast to com.atlassian.upm.api.license.PluginLicenseManager”

Error creating bean with name 'pluginLicenseStoragePluginInstaller' defined in URL [bundle://XXX:0/META-INF/spring/atlassian-plugins-components.xml]: 

Instantiation of bean failed; nested exception is java.lang.NoClassDefFoundError: org/slf4j/LoggerFactory

Tips

Please try upgrading your UPM "Universal Plugin Manager" to the latest for both cases. This is done through the Confluence > Administration > Settings > Manage Apps. You can search for the "Atlassian UPM". You can also find the UPM on the Atlassian Marketplace.

Other users have reported that upgrading the UPM will fix this problem.

If you cannot upgrade the UPM, you can roll back to an earlier version of the MultiExcerpt if that works for you. All older releases are available here: https://appfire.atlassian.net/wiki/display/CMEP/releases
