java - 云类型转换厂 : How use Java Buildpack specific version

Question

我正在尝试将 Spring Boot 应用程序部署到 Cloud Foundry。我已经在 manifest.yml 中给出了构建包，如下所示

---
applications:
- name: gl-bo-sample
  path: ./target/gl-1.0-SNAPSHOT.jar
  buildpacks:
      - https://github.com/cloudfoundry/java-buildpack.git

现在我尝试将它用于特定版本，我尝试将 URL 更改为

https://github.com/cloudfoundry/java-buildpack.git#4.26

但低于错误

buildpack git URL 中的 anchor 应以 v 为前缀，如

https://github.com/cloudfoundry/java-buildpack#v4.26
