Examples don't work

When following the instructions, I get an error. After removing the split after -cp .:\, I get the following output:

Hi,

Thank you for the bug report. There are some missing dependencies in README.md:

1. ~/.m2/repository/args4j/args4j/2.33/args4j-2.33.jar
2. ~.m2/repository/org/choco-solver/pf4cs/1.0.5/pf4cs-1.0.5.jar

I need to update instructions.

I previously download, thanks to maven, the missing jar files and were able to execute Nonogram:

javac -d classes -sourcepath ./src/main/java/ -cp .:~/.m2/repository/args4j/args4j/2.33/args4j-2.33.jar:~/.m2/repository/org/choco-solver/pf4cs/1.0.5/pf4cs-1.0.5.jar:lib/choco-solver-4.0.5-with-dependencies.jar src/main/java/org/chocosolver/samples/integer/Nonogram.java

java -cp classes:~/.m2/repository/args4j/args4j/2.33/args4j-2.33.jar:~/.m2/repository/org/choco-solver/pf4cs/1.0.5/pf4cs-1.0.5.jar:lib/choco-solver-4.0.5-with-dependencies.jar org.chocosolver.samples.integer.Nonogram -f -d rabbit

I can provide a jar file with dependencies which allows me to reduce the steps to only two: downloading then executing. Would something like that be better for quick testing of samples or you prefer loading the source in an IDE, declare the classpath and play with the code ?
