调研方向

重复的依赖来自为 spring-boot 库生成的 pom.xml 支持模板，因此请先在 Java spring-boot 生成器的资源中搜索 spring-boot-starter-restclient。确认它同时出现在 compile 和 test 两个作用域中，然后删除 test 作用域的副本。当生成的 pom.xml 只声明一次该依赖，且生成的项目在 Maven 3.10 下可通过 mvn clean package 成功构建时，即完成。

Description

Yesterday our pipelines using openapi generator CLI via docker images started failing. It turned out the underlying agents where updated to using Maven 3.10 (previously 3.9).

That change in Maven now treats certain duplicated dependencies in the POM as an error instead of just a warning being logged.

The error is related to org.springframework.boot:spring-boot-starter-restclient being duplicated in the Maven pom.xml compile and test scope. As needed for compile there is no need to redeclare for test also.

openapi-generator version

  • v7.26.0
  • no regression I'd say

OpenAPI declaration file content or url

not related to the OpenAPI schema itself, the respective generated Maven POM (support file?) is erronuous

Generation Details

  • using openapitools/openapi-generator-cli from Docker distribution
  • using the following config.yaml
artifactId: "whatever-server"
groupId: "my.org.system"
apiPackage: "my.org.system.whatever.server"
modelPackage: "my.org.system.whatever.server.model"
configPackage: "my.org.system.whatever.server"
library: "spring-boot"
artifactVersion: "0.0.10-20261009.t064033"
openApiNullable: "false"
modelPropertyNaming: "camelCase"
useSpringBoot4: "True"
useJackson3: "True"
useJakartaEe: "false"
interfaceOnly: "true"
delegatePattern: "false"
useResponseEntity: "false"
useBeanValidation: "true"
skipDefaultInterface: "true"
generateBuilders: "true"
generateApiTests: "false"
generateModelTests: "false"

Steps to reproduce

Just use the spring-boot Java generator and try to mvn clean package the outcome.
You will encounter a maven build error stating that spring-boot-starter-restclient is duplicated.

[ERROR]     'dependencies.dependency.(groupId:artifactId:type:classifier)' must be unique: org.springframework.boot:spring-boot-starter-restclient:jar -> duplicate declaration of version (?) @ line 78, column 21

none identified so far

Suggest a fix

It could be as easy as just fixing the respective pom.xml mustache template and remove the duplicated spring-boot-starter-restclient from the test scoped dependencies, as it is compile scope already and does not need to be repeated.
