CI: Rework publish pipeline for "openapi-generator-gradle-plugin"

Created by: jmini

The automated deploy of the openapi-generator-gradle-plugin is not working.

With 3.0.1 and 3.0.2 there was a TravisCI timeout in the job. With 3.0.3 the TravisCI Job is OK.

Log: https://api.travis-ci.org/v3/job/397359374/log.txt

Maven deploy:

Log Extract: end of the maven deploy step:

Finished mvn clean deploy for master

Gradle Uplaoad:

Welcome to Gradle 4.7!

Here are the highlights of this release:
 - Incremental annotation processing
 - JDK 10 support
 - Grouped non-interactive console logs
 - Failed tests are re-run first for quicker feedback

The artefacts were uploaded to Nexus. But a look in the Staging repository show multiple staging repo:

https://oss.sonatype.org/#stagingRepositories

Nexus

Content of the different repos:

  • openapitools-1031 contains only:
    • /org/openapitools/openapi-generator-gradle-plugin/3.0.3/openapi-generator-gradle-plugin-3.0.3.pom.asc.md5
  • openapitools-1030 contains:
    • /org/openapitools/openapi-generator-gradle-plugin/3.0.3/openapi-generator-gradle-plugin-3.0.3-javadoc.jar.sha1
    • /org/openapitools/openapi-generator-gradle-plugin/3.0.3/openapi-generator-gradle-plugin-3.0.3-sources.jar
    • /org/openapitools/openapi-generator-gradle-plugin/3.0.3/openapi-generator-gradle-plugin-3.0.3.jar.asc.md5
  • … and so on
  • openapitools-1024

This is a known issue:

https://issues.sonatype.org/browse/OSSRH-37302?attachmentViewMode=list

I see multiple solutions:

1/ Use the nexus-staging-maven-plugin:

My understanding (see also #366) is that if we manage to install the artifacts (jars, pom, signature files) to <root repo>/target/nexus-staging/deferred/ during the maven build (as a regular step of the openapi-generator-gradle-plugin-mvn-wrapper project) then it will be uploaded in one step at the end of the build.

This is more or less what is recommended in OSSRH-37302

2/ Switch CI Server. According to @jimschubert there is no problem with GitLab-CI

3/ Switch Staging server.

  • Deploy to Bintray (instead of Sonatype Nexus)
  • From Bintray to JCenter and Maven Central (one click)

Bintray is free for Open Source project.

I think that a lot of projects using gradle are using Bintray. I think that AsciidoctorJ is doing it like this.
