springdoc-openapi-maven-plugin:generate fails if the target directory doesn't exist #3

Closed ghost closed 4 years ago

ghost commented 4 years ago

I have a module in a multi-module project that is just for generating the OpenAPI file by adding the necessary dependencies. Since there's no code in this module, I have disabled maven-jar-plugin. The openapi generate goal fails since the target directory is not created.

[INFO] --- springdoc-openapi-maven-plugin:0.2:generate (integration-test) @ obfuscated-integration ---

Hi,

If the target doesn't exist, you can use the following configuration to declare the output directory, that the plugin can use:

 <configuration>
  <outputDir>/home/springdoc/maven-output</outputDir>
 </configuration>
