在Openshift 3.11中使用fabric8 8-maven-plugin (4.4.0)构建时，ImageChange触发器未在deploymentConfig中设置

Question

我正在为openshift构建一个使用maven和fabric8-maven-plugin的spring引导java应用程序。

我正在运行的命令行是：

mvn -Dfabric8.mode=openshift -Ddocker.skip=true clean install fabric8:resource fabric8:build fabric8:apply -Dfabric8.skipResourceValidation

我的openshift deploymentConfig在：

demo/src/main/fabric8/deployment.yml

因此，我希望在命名空间my-namespace中创建的my-namespace将具有如下图像触发器：

apiVersion: apps.openshift.io/v1
kind: DeploymentConfig
metadata:
...
spec:
....
  test: false
  triggers:
    - imageChangeParams:
        automatic: true
        containerNames:
          - demo
        from:
          kind: ImageStreamTag
          name: 'demo:latest'
          namespace: my-namespace
      type: ImageChange

但事实并非如此。对于为什么在生成的部署配置中没有创建映像触发器有任何建议吗？

这是已经修复的Fabric8 Maven插件中的一个bug。它可以在v4.4.1中使用。我们现在正致力于将Fabric8 Maven插件更名为月食JKube。如果你能尝试一下(它和FMP一样，只是没有Fabric8品牌)，我会很感激的。将来，Fabric8 Maven插件将被标记为不推荐使用Eclipse插件，以支持JKube。我用您提供的代码和Eclipsepom.xml创建了一个简单的项目：

https://github.com/r0haaaan/fmp-openshift-sample-with-fragments

在运行oc:resource目标之后，您可以看到现在正在生成触发器：
