Error while trying to get build script read the java file - Could not resolve all artifacts for configuration ':classpath' - spring-boot

Question

I'm trying to follow this by adding my own custom java file into the classpath
https://github.com/gigaSproule/swagger-gradle-plugin#model-converters
This is shown in the example above
buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath 'com.custom:model-converter:1.0.0'
}
}
...
swagger {
apiSource {
...
modelConverters = [ 'com.custom.model.Converter' ]
}
}
This is my code
buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath("com.test.app.profile.component.MyOpenApiCustomiser:1.0.0")
}
}
swagger {
apiSource {
...
modelConverters = [ 'com.test.app.profile.component.MyOpenApiCustomiser' ]
}
}
This is the error I'm getting
A problem occurred configuring root project 'profile'.
> Could not resolve all artifacts for configuration ':classpath'.
> Could not find com.test.app.profile.component.MyOpenApiCustomiser:1.0.0:.
Required by:
project :
Possible solution:
- Declare repository providing the artifact, see the documentation at https://docs.gradle.org/current/userguide/declaring_repositories.html
I tried removing 1.0.0
Caused by: org.gradle.api.IllegalDependencyNotation: Supplied String module notation 'com.test.app.profile.component.MyOpenApiCustomiser' is invalid. Example notations: 'org.gradle:gradle-core:2.2', 'org.mockito:mockito-core:1.9.5:javadoc'
Not sure how I would get my build script to the use the MyOpenApiCustomiser in my spring boot application
Is there any other way or how to fix this?

Answer 1

The classpath dependency given in the buildscript.dependencies {} block needs to be a external library, given in the standard group:modulde:version notation; in the example from github project it's "com.custom : model-converter : 1.0.0" ( it's a "fake" library, does not really exist in maven central repo, it's just an example)
In your case, it seems you try to refer your class MyOpenApiCustomiser as the classpath library , which cannot work. It needs to be a real library.
If you want to use your own Converter, you'll need to implement it in another library/module, publish it to a private repository and then consume it in your buildscript classpath.
Another simpler way, would be to implement this converter as a class within the buildSrc project: these classes will then be automatically available in your build script classpath, and you can use it in the apiSource configuration.
Sample:
In your buildSrc project
build.gradle
plugins {
id("java")
}
repositories {
mavenCentral()
}
dependencies {
implementation "io.swagger:swagger-core:1.6.2"
}
Your custom ModelConverter class goes under src/main/java, e.g. com.sample.MyCustomConverter
In your root build.gradle script:
You can reference your MyCustomConverter class, it's already available in the script classpath, no need to define a classpath dependency in buildscript
swagger {
apiSource {
modelConverters = [ 'com.sample.MyCustomConverter' ]
// ....
