Error: Could not find or load main class Swagger Codegen

Question

I left an open issue for here

---

I´m trying to create a custom codegen, I managed to make it work by putting the files inside of the codegen project but I want it to work like this: https://github.com/swagger-api/swagger-codegen#making-your-own-codegen-modules

I haven't modified the autogenerated project at all but I keep getting:

Error: Could not find or load main class io.swagger.codegen.SwaggerCodegen

This is the command line:

java -cp output/myLibrary/target/myCustomCodegen-swagger-codegen-1.0.0.jar:swagger-codegen-cli-2.1.6.jar io.swagger.codegen.SwaggerCodegen generate -i https://watson-api-explorer.mybluemix.net/listings/conversation-v1-experimental.json -l com.my.company.codegen.Mycustomcodegengenerator -o outputlocation 

I got the jar from here https://mvnrepository.com/artifact/io.swagger/swagger-codegen-project/2.1.6 This is what I'm doing:

1. Run java -jar swagger-codegen-cli-2.1.6.jar meta \ -o output/myLibrary -n myClientCodegen -p com.my.company.codegen to create costume codegen

2. Run mvn package in output/myLibrary

3. Run java -cp output/myLibrary/target/myCustomCodegen-swagger-codegen-1.0.0.jar:swagger-codegen-cli-2.1.6.jar io.swagger.codegen.SwaggerCodegen generate -i https://watson-api-explorer.mybluemix.net/listings/conversation-v1-experimental.json -l com.my.company.codegen.Mycustomcodegengenerator -o outputlocation in the folder that contains both swagger-codege-cli-2.1.6.jar and the output folder

It does find the class if I remove the first part, but doesn´t find the new language:

java -cp swagger-codegen-cli-2.1.6.jar io.swagger.codegen.SwaggerCodegen generate -i https://watson-api-explorer.mybluemix.net/listings/conversation-v1-experimental.json -l com.my.company.codegen.Mycustomcodegengenerator -o outputlocation 

I have looked at the answers for "Error: Could not find or load main class" problems but haven't manage to fix it.

Here is a link to the jar

For Windows, change the colon (:) to a semicolon (;) - between the jars in the class path. So instead of

java -cp output/myLibrary/target/myCustomCodegen-swagger-codegen-1.0.0.jar:swagger-codegen-cli-2.1.6.jar io.swagger.codegen.SwaggerCodegen generate -i https://watson-api-explorer.mybluemix.net/listings/conversation-v1-experimental.json -l com.my.company.codegen.Mycustomcodegengenerator -o outputlocation

It should be

java -cp output/myLibrary/target/myCustomCodegen-swagger-codegen-1.0.0.jar;swagger-codegen-cli-2.1.6.jar io.swagger.codegen.SwaggerCodegen generate -i https://watson-api-explorer.mybluemix.net/listings/conversation-v1-experimental.json -l com.my.company.codegen.Mycustomcodegengenerator -o outputlocation

Multiple class paths need to be separated by a semicolon. http://docs.oracle.com/javase/7/docs/technotes/tools/windows/classpath.html
