Description

Project has dependecny on shiro-core and shiro-web, no other shiro artifacts.

When shading (maven plugin) the project WARNING's are emitted:

[WARNING] shiro-crypto-hash-1.5.1.jar, shiro-core-1.5.1.jar define 24 overlapping classes: 
[WARNING]   - org.apache.shiro.crypto.hash.format.ProvidedHashFormat
[WARNING]   - org.apache.shiro.crypto.hash.format.HexFormat
[WARNING]   - org.apache.shiro.crypto.hash.Sha1Hash
[WARNING]   - org.apache.shiro.crypto.hash.Md2Hash
[WARNING]   - org.apache.shiro.crypto.hash.ConfigurableHashService
[WARNING]   - org.apache.shiro.crypto.hash.HashRequest
[WARNING]   - org.apache.shiro.crypto.hash.format.Shiro1CryptFormat
[WARNING]   - org.apache.shiro.crypto.hash.format.HashFormat
[WARNING]   - org.apache.shiro.crypto.hash.Sha256Hash
[WARNING]   - org.apache.shiro.crypto.hash.format.DefaultHashFormatFactory
[WARNING]   - 14 more...

and a 3 way one:

[WARNING] shiro-config-ogdl-1.5.1.jar, shiro-config-core-1.5.1.jar, shiro-core-1.5.1.jar define 5 overlapping classes: 
[WARNING]   - org.apache.shiro.config.Ini$1
[WARNING]   - org.apache.shiro.config.Ini$Section
[WARNING]   - org.apache.shiro.config.ResourceConfigurable
[WARNING]   - org.apache.shiro.config.Ini
[WARNING]   - org.apache.shiro.config.ConfigurationException

Looking in the jars, indeed both shiro-crypto-hash-1.5.1.jar, shiro-core-1.5.1.jar have the same classes. It is as if shiro artifacts include parts of shiro-core that they use.
