Hi, thoqbk! I have downloaded the repository and I find there existing some error when use maven to packaging the jar. The error message are as follows:

[ERROR] COMPILATION ERROR :

I continue to move the project into Eclipse. After I fixed the libraries settings according to the pom.xml and import suggestions, the following code in PDFTableExtractor.java are suggested wrong.

this.textPositions.sort(new Comparator<TextPosition>() {

This appeared in many other java files, e.g. TrapRangeBuilder, and TESTPDFBox. And here is the Eclipse suggestion:

The method sort(new Comparator<Range>(){}) is undefined for the type List<Range<Integer>>

Could you make it clear how you implement the sort method?
Thank you very much.

Hi friend!

My current implementation uses some Java 8 methods so it doesn't work in your environment.

The easiest way to make it run is upgrade the environment to Java 8, otherwise you can replace this statement by using method: Collections.sort.

I'm sorry because I didn't clarify it before.

Thank you so much!

Thanks for your reply! I have fixed that by using Java 8.
