AEM 6.1扩展ThumbnailProcess工作流步骤

Question

我正在尝试扩展com.day.cq.dam.core.process.ThumbnailProcess类。

我使用的是Java JDK 1.8.0_65、Maven 3.0.5和Adobe AEM6.1

当我编译代码时,我会得到以下错误：

[错误]无法在项目my.pack.common.process上执行目标org.apache.felix:maven-scr-plugin:1.20.0:scr（generate-scr-plugin:1.20.0:scr）失败：执行org.apache.felix:maven-scr-plugin:1.20.0:scr时遇到API不兼容：（类：com/day/cq/dam/core/process/thumbnailprocess,方法：签名：（）V）构造函数必须调用super（）或this（）

我的课是这样的：

@Component
@Service
@Properties({
@Property(name = Constants.SERVICE_DESCRIPTION, value ="MyThumbnailProcess"),
@Property(name = Constants.SERVICE_VENDOR, value = "Me"),
@Property(name = "process.label", value = "My Thumbnail Proc2")}
public class MyThumbnailProc extends ThumbnailProcess {
public MyThumbnailProc(){super();}
@Override
public void execute(WorkItem workItem, WorkflowSession workflowSession, MetaDataMap metaData) throws WorkflowException {
//do stuff -> create newMetaDataMap 
super.execute(workItem, workflowSession, newMetaDataMap);
}

你有什么建议吗？

Answer 1

作为测试，您可以尝试aem6 api依赖项，而不是6.1uber JAR。我猜你是在扩展一个模糊的类。如果您能够通过6.0依赖关系解决这一问题，那么您可以向Adobe请求未关闭的6.1 jar
