(I'm using jdk1.8.0_181)
I include a dependency for Apache Tika in my project as follows:
<dependency org="org.apache.tika" name="tika-parsers" rev="1.21"/>
However, when building, I get an error for one of Tika's dependencies. Specifically:

If I look at the log during the build, under "resolving dependencies", I see:
found org.apache.logging.log4j#log4j-api;2.10.0 in public
As you can see though, there is a discrepancy between the locations. One is in
log4j-api
and the other is in
log4f-api-java9
I think this is what's leading to the error, ivy is looking for the dependency in a folder that does not exist (log4j-api-java9). I'm not sure why it's looking there. How can I fix this?
This question appears to address a similar issue but it doesn't have an answer.
Would it be safe to simply exclude the log4j-api-java9 module?
I excluded the dependency from my build:
log4j-api-java9
(I'm not using Java 9 so I feel safe doing this).
