Hi all,
I have JDK and Maven tools installed in my Jenkins global configuration.
So, I could use the command exactly as provided in this tutorial
<https://github.com/jenkinsci/workflow-plugin/blob/master/TUTORIAL.md>.
def mvnHome = tool 'Default Maven'
>

However, I'm getting the following exception because of another tool I have
installed in there:
java.lang.ClassCastException: custom.jenkins.bw.BWInstallation$DescriptorImpl
cannot be cast to hudson.tools.ToolDescriptor

The tool in question is a custom implementation, a bit old but still used.
My job isn't interested in this custom tool at all, but I cannot simply
removed it from there because other jobs (not using Workflow) still depend
on it.
I believe the custom tool isn't compliant with the Workflow plugin. Just in
case, below is the signature of the Descriptor of our custom tool:
@Extension
> public static class DescriptorImpl extends
> Descriptor<ToolInstallation> {
>
Shouldn't the Workflow plugin simply ignore tools which aren't compliant
with it instead of raising such exceptions? Is there any workaround for it?
