Plugin NoClassDefFoundError [message #1292153]

Hi, I have a plugin that I've been developing that I import:

import org.jfree.data.general.DefaultPieDataset;

To create a graph, this works fine in Jenkins, but in Hudson I get:

FATAL: org/jfree/data/general/PieDataset
java.lang.NoClassDefFoundError: org/jfree/data/general/PieDataset

         ... 11 more

So I thought something must be off with the dependencies, commenting out this import and code using it solves the issue, but then I get the same with: hudson.util.Graph;

so now im confused... any ideas? also using 3.1.2 hudson

Hudson graphing interface is abstracted to use jfreechart or any other graphing technology. jfreechart is move to a plugin. If you want to use jfreechart, then add jfreechart-plugin as dependency to your plugin

<dependency>
    <groupId>org.hudsonci.plugins</groupId>
    <artifactId>jfreechart-plugin</artifactId>
    <version>1.5</version>
</dependency>

Thanks, that resolved that issue, but now its bumped into the same for:

hudson.util.Graph

I tried adding:

<dependency>
    <groupId>org.jvnet.hudson.main</groupId>
    <artifactId>hudson-core</artifactId>
    <version>2.2.1</version>
</dependency>

But now I get the error:

error: javax.annotation.processing.FilerException: Attempt to reopen a file for path ConfigFailNew.stapler

Just looking to see if im going down the right path here?

Hi Michael, hudson.util.Graph is part of the jfreechart-plugin, if you include that plugin as your dependency your plugin should build fine. Do not directly add core as dependency. BTW, if your plugin is somewhere in github I can take a look at it.
