[jira] (MDEP-123) dependency:tree to optionally display all
instances of a transitive dependency, not just the first one found
[ https://jira.codehaus.org/browse/MDEP-123?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=333705#comment-333705 ]
Roger Pack commented on MDEP-123:
---------------------------------
It appears that with -Dverbose=true it lists duplicates like
[INFO] | | +- (commons-httpclient:commons-httpclient:jar:3.1:compile - omitted for duplicate)
or
[INFO] | | | \- (com.sun.jersey:jersey-client:jar:1.2:compile - omitted for conflict with 1.1.4.1)
@William is that the "solution" you were referring to?

> dependency:tree is *really* useful for tracking down how a particular transitive dependency has been introduced, but it only lists the first occurrence, not all occurrences. So it can be frustrating game attempting to remove a dep only to find it introduced by another component. A parameter to dependency:tree to show all occurences of a transitive dep would be *really* helpful.
> Eg the attached POM has a direct dep on commons-beanutils and commons-digester, which both have a dep on commons-logging. But executing
> {code}
> mvn org.apache.maven.plugins:maven-dependency-plugin:2.0-alpha-5-SNAPSHOT:tree
> {code}
> only shows commons-logging listed as a transitive dep for commons-beanutils, not commons-digester, Ie
> {code}
