• system (jars already present in j2ee container; listed manually with explic

Answer 1

While provided dependencies exclusion is possible with Maven and Gradle, it seems that currently there is no way to easily achieve it with ivy.

Update

In some cases the task can be worked around with intermediate induced module and negative regexp mask:

    <dependency org="com.company" name="root.module" conf="ear" rev="latest.integration">
        <exclude org="^(?!com.company).*$" matcher="regexp"/>
    </dependency>

But we've already moved to Gradle as Ivy seems to be losing momentum.
