Configuring the following test task gives an NPE exception caused by building a MissingMethodException with arguments == null.
Simple test case is a TestNG project with the following task configuration:
task testTask(type: Test) {
useTestNG() {
suiteXmlBuilder()
println "Name of enclosing task: $name"
}
}
The exception is:
java.lang.NullPointerException
