Android Docx4J duplicate classes error

[f80m3]

I am trying to follow the GitHub example here: https://github.com/plutext/Docx4j4Android4 to import the Docx4J library into my Android app. However, when I run my Android app, I get the following error (There are many errors, but they all belong to duplicate classes relating to org.apache.commons.lang3.* and org.sl4j.spi.*):

Duplicate class org.apache.commons.lang3.AnnotationUtils found in modules commons-lang3-3.7.jar (commons-lang3-3.7.jar) and docx4j-6.1.1-SNAPSHOT-shaded.jar (docx4j-6.1.1-SNAPSHOT-shaded.jar)
.......
Duplicate class org.slf4j.spi.MarkerFactoryBinder found in modules docx4j-6.1.1-SNAPSHOT-shaded.jar (docx4j-6.1.1-SNAPSHOT-shaded.jar) and slf4j-android-1.6.1-RC1.jar (slf4j-android-1.6.1-RC1.jar)

I need to use the commons-lang3-3.7jar and the commons-text-1.2.jar's classes in my app.

If you want to use those standalone jars, you'll need to remove the org.slf4j and org.apache.commons.lang3 packages from docx4j-6.1.1-SNAPSHOT-shaded.jar.

I need to get around to doing a Android version of docx4j 8.1.x...

How would I go about removing the org.slf4j and org.apache.commons.lang3 packages from docx4j-6,1,1-SNAPSHOT-shaded.jar?
