Bob Tiernay commented on MSHADE-128:
------------------------------------
Bump (in the most polite manner possible :)
> Too many warnings "We have duplicates"
> --------------------------------------
>
> Key: MSHADE-128
> URL: https://jira.codehaus.org/browse/MSHADE-128
> Project: Maven 2.x Shade Plugin
> Issue Type: Improvement
> Affects Versions: 1.7.1
> Reporter: Raffaele
> Assignee: Benson Margulies
> Attachments: pom.xml, warning-we-have-duplicates.patch
>
>
> When creating an uberjar, sometimes the same class is present in two or more
> dependencies' JARs. For each class, maven-shade-plugin issues a WARNING We
> have a duplicate in.
> This is annoying and can muddle newcomers up (like myself), because it's not
> clear how to fix.
> I don't know if a programmatic solution to these warnings could exist: maybe
> it will always require human interaction. However, it's better to point users
> in the right direction and not spit out thousands of useless warnings.
> Attached is a pom which triggers thousands of warnings and a patch with a
> prettier (and hopefully more useful) output like
> [WARNING] bcprov-jdk14-138.jar, bcprov-jdk14-1.38.jar define 1292
> overlappping classes:
> [WARNING] - org.bouncycastle.asn1.ocsp.ResponderID
> [WARNING] - org.bouncycastle.crypto.params.DSAPublicKeyParameters
> [WARNING] - org.bouncycastle.crypto.engines.DESEngine
> [WARNING] - org.bouncycastle.jce.provider.JCEElGamalPrivateKey
> [WARNING] - org.bouncycastle.jce.provider.JCEStreamCipher$Skipjack_CFB8
> [WARNING] - org.bouncycastle.jce.provider.JCESecretKeyFactory
> [WARNING] - org.bouncycastle.i18n.filter.UntrustedInput
> [WARNING] - org.bouncycastle.asn1.x9.X962NamedCurves$5
> [WARNING] - org.bouncycastle.jce.X509KeyUsage
> [WARNING] maven-shade-plugin has detected that some .class files
> [WARNING] are present in two or more JARs. When this happens, only
> [WARNING] one single version of the class is copied in the uberjar.
> [WARNING] Usually this is not harmful and you can skeep these
> [WARNING] warnings, otherwise try to manually exclude artifacts
> [WARNING] based on mvn dependency:tree -Ddetail=true and the above
> [WARNING] output
> [WARNING] See http://docs.codehaus.org/display/MAVENUSER/Shade+Plugin
