I am currently doing code about file upload in Liferay and I am getting an error like below.

It states org.apache.commons.io; version="[1.4.0,2.0.0) and means you need ..commons.io version 1.4.0 up to 2.0.0 but you defined a dependency for 2.5.
So either your bnd.bnd is wrong or your maven/gradle setup is wrong.
