How to enable Apo Commons IO in Eclipse? (Java)

Question

How to configure an Eclipse installation to use classes from Apache Commons IO ?

I want to use this code:

IOUtil.write(encoded, new FileOutputStream(new File("target-file.txt"))) 

But this gives an error:

IOUtil cannot be resolved

Answer 1

You can also use the built-in eclipse plug-in tools like m2eclipse or IAM (formerly Q4e ).

IAM can be installed after these instructions , and ha sa great dependency viewer

The differences between m2eclipse and IAM are discussed here , there and here .

Q4E is event oriented, I believe m2e uses console and stdin / out.

The big thing is that m2eclipse forks uses external maven (to run maven targets), while iam/q4e uses only the built-in .
Our position here is that it is a way to integrate more deeply and improve productivity.
This, of course, allowed us to quickly do things like look at dependency analysis and some other “magic” in the incremental maven builder.
