build.gradle was not able to download the jar i mentioned:

build.gradle : "compile 'org.apache.commons:commons-csv:1.1"

So i download the commons-csv jar from below link and added externally into the project

commons-csv.jar

binaries: commons-csv-1.4-bin.zip

you have to add commons-csv as a dependency.

If you use gradle as your question is tagged, add these line:

// https://mvnrepository.com/artifact/org.apache.commons/commons-csv
compile group: 'org.apache.commons', name: 'commons-csv', version: '1.4'
