    Description

      On the web page of a branch of a multibranch project, the warnings trend chart does not render. Instead, there is a placeholder with a progress ring and the text "loading". The developer tools in the Web browser show HTTP status 500 from a POST /jenkins/$stapler/bound/6d08ec1b-ebf8-4765-ad4e-b89a4089ea71/getBuildTrendModel request, and the Jenkins log shows various exceptions, depending on plugin and JVM versions and perhaps other things:

      • java.lang.NoClassDefFoundError: edu/hm/hafner/echarts/LineSeries
      • java.lang.LinkageError: edu.hm.hafner.echarts.LineSeries
      • java.lang.LinkageError: A duplicate class definition for edu/hm/hafner/echarts/JacksonFacade is found
      • java.lang.LinkageError: loader (instance of hudson/ClassicPluginStrategy$AntClassLoader2): attempted duplicate class definition for name: "edu/hm/hafner/echarts/JacksonFacade"

      The classes edu.hm.hafner.echarts.LineSeries and edu.hm.hafner.echarts.JacksonFacade are defined in both plugins/echarts-api/WEB-INF/lib/echarts-api.jar and plugins/echarts-api/WEB-INF/lib/echarts-build-trends-2.0.0.jar. Those jar files are included in plugins/echarts-api.jpi (ECharts API Plugin 5.0.1-1). This seems to be a bug in that plugin, then.
