No signature of method is applicable for argument types when trying to publish to JCenter with gradle

I'm trying to publish my project to JCenter with gradle.
I'm getting this error:

Bintray is dead.
But to answer the question, No signature of method: build_whatever.[method]() comes from something in the configuration of [method] being incorrect. In this case I'd guess it's caused by released new Date() which should probably be released = new Date()

Mixing Java and Kotlin with gradle - NoClassDefFoundError

Gradle Multi Module Product : Compiling module which depends on another

I am coming from Maven workd and new to Gradle.I have multi-module Gradle product with following modules:
"cdna-common"
'cdna-data-access'
"cdna-api-dto"
"cdna-api-module"
"cdna-request-executor-module"
my root settings.glade looks like this:
rootProject.name = 'cdna-one-platform'
include "cdna-common"
include 'cdna-data-access'
//include "cdna-api-dto" //commented temporary
include "cdna-api-module"
//include "cdna-request-executor-module" //commented temporary
gradle file for module 'cdna-data-access' is :
buildscript {

Module 'cdna-common' depends on 'cdna-one-data-access' and gradle file looks like :

When I compile the module 'cdnHowever,cess' using 'gradlew cdna-data-access:build' , it compiles without any error.
However , when I try to compile the module 'cdna-common' using 'gradlew cdna-common:build' , it gives following error:

Project was generated via start.spring.io site.

After some tests, I've found out my problem. That was an NPE exception in init method of my bean annotated with #PostConstruct. You can reproduce this issue like this:
#Component
class Test {
String str;
#PostConstruct
private void init() {
System.out.println(str.length());
}
}
I don't understand why spring throws so unclear exception.

I don't understand how to add the dependency.

It means that the dependency com.jme3:xmlpull-xpp3:3.0.0.20140325-SNAPSHOT does not exist in the repositories you specified.
Possible reasons:
You misspelled the dependency.
You left out a repository.
Your local Maven repository or gradle cache are broken.
Consider looking at the dependency tree to figure out where this dependency comes from and what to do to resolve the issue.
