This is true for jar dependencies.
But if the war file depends on an artifact with type ejb
(<type>ejb</type>), the skinnywar-option ignores this dependency and let it
remain in war/lib.
And if there are two war files WAR1 and WAR2 depending on the same artifact
with type ejb, the ear isn't deployable as the beans within the
ejb-artifact resist in WAR1/lib _and_ WAR2/lib. The container tries to
deploy beans from both loations and struggles as it cannot deploy the same
bean twice.
We found a workaound. We define all dependencies without the type-tag to
keep the skinnywar-option working. To avoid malicious packaging inside the
EAR, we define all these dependencies as jarmodules with explicit deploy
path and entry in the application.xml. Such a definition looks like
<jarModule>
<groupId>groupid</groupId>
<artifactId>artifactid</artifactId>
<includeInApplicationXml>true</includeInApplicationXml>
<bundleDir>/</bundleDir>
</jarModule>
Ugly but working.
