Maven plugin - exclude dependencies - Doesn't work transitively

[tenstriker]

I tried following to exclude all the artifacts under following groups

                 <configuration>
                <excludeGroupIds>org.apache.hadoop</excludeGroupIds>
                <excludeGroupIds>org.apache.hbase</excludeGroupIds>
            </configuration>

But it still left me with some jars . It should work same as maven-shade plugin artifactSet -> excludes in my opinion.

Duplicates #3426

Why not? In what scenario one would want child dependencies in their project when they don't want parents? Can there be a flag to exclude it conditionally at least?
Please re-open or give justifiable reason why this functionality is no supported.

In my case I use 'excludeGroupIds' which should excludes all the artifacts under that group but that's is no happening.

e.g. hadoop-mapreduce-client-core, hadoop-yarn-common etc are all under same group id. If you can't exclude them then what is the point. I would happily use shade plugin but that plugin has its own issue as well working with spring-boot jars.

Ah, I see. That wasn't at all clear from the original description

The doc states:

Comma separated list of groupId names to exclude (exact match).

Can you fix your configuration first please?

<configuration>
    <excludeGroupIds>org.apache.hadoop,org.apache.hbase</excludeGroupIds>
</configuration>

@wilkinsona I tried comma-separated list of group ids. It still doesn't exclude child dependencies.

[wilkinsona]

As explained in #3426, the exclusions are not applied transitively and it will only exclude artifacts with a group id that matches those specified in <excludeGroupIds>. I've just packaged an application and verified that all dependencies with a group id of org.apache.hadoop or org.apache.hbase are excluded, i.e. this is working as designed.

mvn dependency:copy-dependencies copy all jars to target/dependency;

mvn dependency:tree, get all groupIds, then it works.

Can anyone reopen this issue? What's the point that if I want to just exclude a dependence without its dependence?
