Server fails to generate integrations with Open APIs

Details

    Description

      When syndesis-server creates the integration project for an Open API provider integration we run into:

      Integration [cobol-to-xml]: Created project files and starting build
Exception in thread "pool-9-thread-1" java.lang.NoClassDefFoundError: com/squareup/javapoet/MethodSpec

      The missing class is part of the javapoet library which is a transitive dependency of camel-openapi-rest-dsl-generator. Most likely the exclusion of all transitive dependencies in server-controller pom.xml cause this behavior:

      https://github.com/syndesisio/syndesis/blob/master/app/server/controller/pom.xml#L62-L76

      So we need to find another way to resolve dependency issues in server-controller pom.xml.

      This happens only on upstream master at the moment.

          Bug - A problem that impairs or prevents the functions of the product. ENTESB-13841 API Provider step doesn't work

          • Blocker - To be worked above all other priorities. This term is chosen when the severity of the issue is very high, has no workaround, or the effort for the change is comparatively low. Issues that may be very publicly visible and could generate significant media attention may also drive a higher priority.
