在Openshift 3.11中使用fabric8 maven插件(4.4.0)构建时，deploymentConfig

Question

我正在为openshift构建一个带有maven和fabric8-maven-plugin的spring-boot java应用程序。

我运行的命令行是：

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

我有我的openshift部署配置在：

demo/src/main/fabric8/deployment.yml

因此，我希望在名称空间my-namespace中创建的deploymentConfig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。关于为什么没有在生成的部署配置中创建映像触发器，有什么建议吗？

以下是更多详细信息：

这是Fabric8 Maven插件中的一个错误，已经修复。它在v4.4.1中可用。我们现在正在努力将Fabric8 Maven插件重新命名为Eclipse JKube。如果你能试用一下，我将不胜感激(它和FMP一样，只是没有Fabric8品牌名称(。将来，Fabric8 Maven插件将被标记为不推荐使用Eclipse JKube。我用您提供的代码和pom.xml中的Eclipse JKube:创建了一个简单的项目

运行oc:resource目标后，您可以看到现在正在生成触发器：
