I have the following dsl:

pipelineJob("hello-pipeline") {

     using("/templates/hello") // where hello is a pipeline job
}

Got this exception:

java.lang.NullPointerExceptionat javaposse.jobdsl.plugin.ExecuteDslScripts.updateTemplates(ExecuteDslScripts.java:380)at javaposse.jobdsl.plugin.ExecuteDslScripts.perform(ExecuteDslScripts.java:322)

Looking at the source, this line seems to be the culprit:

AbstractProject templateProject = getLookupStrategy().getItem(seedJob, templateName, AbstractProject.class);
