Eric Milles updated GROOVY-9987:
--------------------------------
Description:
A method call inside a closure that targets a base class private method results
in a {{MissingMethodException}}.
{code:groovy}
class Base {
def baseRun() {
[1].each {
baseRunStatic()
}
}
private static void baseRunStatic() {
println "baseRunStatic()"
}
}
class StaticTest extends Base {
def run() {
baseRun()
}
}
new StaticTest().run()
{code}
Try executing the attached script with Groovy 3.0.7. It will yield:
{code}
❯ groovy test.groovy
Caught: groovy.lang.MissingMethodException: No signature of method:
StaticTest.baseRunStatic() is applicable for argument types: () values: []

As a work around the method call to baseRunStatic() can be prefixed with the
class name.
was:
If a class calls a method on a base class and that method class a static method
inside a closure a MissingMethodException will be thrown at runtime.
{code:groovy}
class Base {
def baseRun() {
[1].each {
baseRunStatic()
}
}
private static void baseRunStatic() {
println "baseRunStatic()"
}
}
class StaticTest extends Base {
def run() {
baseRun()
