def loadGroovyExtensionModules() {
Map<CachedClass, List<MetaMethod>> map = [:]
ClassLoader classLoader = Thread.currentThread().contextClassLoader
try {
Enumeration<URL> resources = classLoader.getResources(MetaClassRegistryImpl.MODULE_META_INF_FILE)
for (URL url in resources) {
if (url.path.contains('groovy-all')) {
// already registered
continue
}
Properties properties = new Properties()
InputStream inStream
try {
inStream = url.openStream()
properties.load(inStream)
GroovySystem.metaClassRegistry.registerExtensionModuleFromProperties(properties, classLoader, map)
} catch (IOException e) {
throw new GroovyRuntimeException("Unable to load module META-INF descriptor", e)
} finally {
inStream?.close()
}
}
} catch (IOException ignored) {}
map.each { CachedClass cls, List<MetaMethod> methods ->
cls.addNewMopMethods(methods)
}
}

If I follow the usage examples on a Grails v2.3.11 application I always get a
MissingMethodExceptionlike the one below:groovy.lang.MissingMethodException: No signature of method: rx.Observable.subscribe() is applicable for argument types: (my.package.TestController$_show_closure1)Seems like the
Subscribe()method does not allow closures, but as per the examples it should allow them.I configured my dependencies like:
Any idea why is this happening? You can use the Hello World example to try reproducing this (it's the one I'm using).
