Swagger-codegen: Build error - My own codegen

[lsarni]

Description

I´m getting an error when I try to build my own codegen. I tried building the project created using
java -jar modules/swagger-codegen-cli/target/swagger-codegen-cli.jar meta -o output/myLibrary -n myClientCodegen -p com.my.company.codegen (to check if I might have written something wrong) and I get the same error.
It looks for io.swagger:swagger-codegen:jar:2.2.0-SNAPSHOT at my maven repository, but it isn´t there.

Command line used for generation

C:\Users\x\Documents\swagger-codegen\output\myLibrary>mvn package -X

encounter the same issue during running testNG tests. any idea to fix it?

[wing328]

It looks for io.swagger:swagger-codegen:jar:2.2.0-SNAPSHOT at my maven repository, but it isn´t there.

You will need to run mvn install to install the jar to your local maven repo.

[wing328]

Please provide more details such as the exact command you executed and the error message.

I'm having the same issue, however I am running mvn install in the correct directory (also, if mvn install is required it should probably be mentioned in the README.md).

This is what I get:

$ mvn install
