swagger codegen cli for openspec 3 - java language generation fails #8218
Comments

The issues seems to be in DefaultGenerator.java line 1013 method getHandlebars. The first part of this method has teh logic: if (tempalteFile.startsWith(config.templateDir())) { template file is: v2\Java\model.mustache |

This only happens in Windows for me, and I think has to do with the backslashes being misinterpreted in the I have received the same error reliably in Windows, although the same commands work fine in macOs. swagger-codegen-cli-3.0.0-20180523.181249-69.jar My command line is And my error message is: This happens in Windows 7 and Windows 10, JRE 8 or 9. I will try to make a local build and fix the line. |

Replacing the private com.github.jknack.handlebars.Template getHandlebars(String templateFile) throws IOException {
if (templateFile.startsWith(config.templateDir())) {
// templateFile = templateFile.replaceFirst(config.templateDir(), StringUtils.EMPTY);
templateFile = StringUtils.replaceOnce(templateFile, config.templateDir(), StringUtils.EMPTY);

@bigtlb - swagger-codegen 3.0.0 rc1 does not seem to have this fix. Do you know if it made to that release candidate? |
|
hey @bigtlb @murthy5 can you please try with https://github.com/swagger-api/swagger-codegen/releases/tag/v3.0.0 and let me know if there is something wrong? |

I have added a fix for this issue in another GitHub issue which is about the same topic. |

Hello, I am still experiencing this issue with the following versions on Windows: Frustrating that this is still an open issue 3 years later.

Description
When I try to generate java stubs from a simple yml api definition I am getting the following error.
I am able to generate using other language types - but were hoping that the "java" language option will yield a set of stubs that are framework agnostic. I would like the generated stubs to be simply the model and an interface for the service.
