What is the difference between maven dependencies org.apache.commons:commons-io and commons-io:commons-io?

Question

Maven repositories contain these two dependencies: org.apache.commons:commons-io:1.3.2 and commons-io:commons-io:1.3.2. What is the difference and which one I should be usin

Answer 1

The deployment of

org.apache.commons:commons-io:1.3.2

Was a mistake that was ultimately fixed by relocating:

POM of org.apache.commons:commons-io:1.3.2

To use commons-io:commons-io:1.3.2.

The mistake was likely an attempt to migrate the Commons IO library to use the current naming convention for Maven groupIds.
