I got the following error during the creation of a new Silk4J project in Eclipse.
interface org.springframework.aop.SpringProxy is not visible from class loader

Looks like your indirect dependencies are not imported you can add those explicitly in your POM and try again
<Import-Package>
...
org.aopalliance.aop,
org.springframework.aop,
org.springframework.aop.framework,
...
</Import-Package>
