Generating own codegen modules issues

[Arseniy]

Hey, 

i've faced troubles with "making your own codegen modules" section from this doc. 

More specifically, after running the provided command

"java -jar modules/swagger-codegen-distribution/target/swagger-codegen-cli.jar meta -o output/myLibrary -n myClientCodegen -p com.my.company.codegen"

and building myLibrary (in the output directory) using

mvn package

i'm trying to follow appropriate advice (from output/myLibrary/Readme.md): "You can now use that with codegen:", so when i try to run

java -cp /path/to/swagger-codegen-distribution:/path/to/your/jar io.swagger.codegen.Codegen -l myClientCodegen -o ./test

which in my simple case equals

java -cp ../../modules/swagger-codegen-cli:target/myClientCodegen-swagger-codegen-1.0.0.jar io.swagger.codegen.Codegen -l myClientCodegen -o ./test

i've got following error:

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

What should i do to avoid this?
Any help will be appreciated.

Hi, a couple things.

First, you probably did successfully create a custom codegen module.  The error you're getting is because of how you're executing it.

There is the swagger-codegen-cli which is a runnable jar.  You can grab it from sonatype directly (http://repo1.maven.org/maven2/io/swagger/swagger-codegen-cli/2.1.4/) and run it with a simple command:

java -jar swagger-codegen-cli-2.1.4.jar help

That should list all the default targets for generating.

Now, you've created a module which the above executable jar can find "automatically".  It just needs to be on your classpath:

java -cp path/to/your/lib.jar -jar swagger-codegen-cli-2.1.4.jar help

That should list your project in the available languages.

Hi,

I also encountering this issue, I've followed the answer from @tony tam

java -jar swagger-codegen-cli-2.1.4.jar help

java -cp path/to/your/lib.jar -jar swagger-codegen-cli-2.1.4.jar help

yes does code work, but when I tried to use this command

java -cp output/library/target/myJarcode-swagger-codegen-1.0.0.jar -jar modules/swagger-codegen-cli/target/swagger-codegen-cli.jar generate -i modules/swagger-codegen/src/test/resources/2_0/petstore.json -l myJarcode -o ./test

But it always throw this error:

Exception in thread "main" java.lang.RuntimeException: Can't load config class with name myJarcode Available: android
async-scala
csharp
....

I hope I can get some help with this? thanks in advance!

Btw, I've run this on Windows 7 OS, I also checked it on my Ubuntu Linux but throwing the same error message..

Yes, you actually have to call it a bit differently when including your custom module along with the executable jar.

java -cp path/to/your/lib.jar:swagger-codegen-cli-2.1.4.jar io.swagger.codegen.SwaggerCodegen generate -l myJarcode

java -cp output/library/target/myJarcode-swagger-codegen-1.0.0.jar -jar modules/swagger-codegen-cli/target/swagger-codegen-cli.jar generate -i modules/swagger-codegen/src/test/resources/2_0/petstore.json -l java -o ./test

worked for me.

It seems we need to give any option available as displayed by the excecption.
