Minor Annoyance: edu.emory.mathcs.backport.java.util

Question

I know this is trivial, but I bet I am not the only developer being annoyed by this issue:

I have a maven project building a Spring Hibernate frameowrk for a webapp. I am building using Eclipse.

I use Eclipse shortcuts to import dependencies and often do so almost subconsciously.

Somewhere in my project dependencies I have a jar that includes the following package.

edu.emory.mathcs.backport.java.util

I often accidentally import this package instead of java.util and get compile or runtime errors.

QUESTION: How can I find out which dependency includes this package so I can (hopefully) exclude it using the Maven enforcer plugin.

Answer 1

This does not directly answer your question but may help you prevent the accidental import in the first place:

In Eclipse you can add a type filter in Preferences → Java → Appearance → Type Filters.

From the description there:

All types whose fully qualified name matches the selected filter strings will not be shown in the 'Open Type' dialog. They will also be ignored in content assist or quick fix proposals and when organizing imports. For example 'java.awt.*' will hide all types from the awt packages.
