ArtifactoryPublish fails with null pointer exception - gradle

Question

I have a java library which I want to upload to jfrog artifactory. But no matter what I do I get a null pointer exception:
Execution failed for task :util-lib-java:artifactoryPublish.
java.lang.NullPointerException (no error message)
It worked perfectly fine on the 3rd October this year, and failed on the 10th. We then referenced version: classpath "org.jfrog.buildinfo:build-info-extractor-gradle:4.*" and what I can see jfrog updated their library from 4.4.5 to 4.47 between these dates. But now when I'm trying with various versions I only get the error specified above.
My build.gradle looks like:
buildscript {
repositories {
jcenter()
maven {
url "${artifactory_contextUrl}/plugins-release"
credentials {
username = "${artifactory_user}"
password = "${artifactory_password}"
}
}
}
dependencies {
//Check for the latest version here: http://plugins.gradle.org/plugin/com.jfrog.artifactory
classpath "org.jfrog.buildinfo:build-info-extractor-gradle:4.4.2"
}
}
apply plugin: 'java'
apply plugin: 'com.jfrog.artifactory'
apply plugin: 'maven-publish'
repositories
{
mavenCentral()
maven {
url "${artifactory_contextUrl}/libs-release-local"
}
maven {
url "${artifactory_contextUrl}/libs-snapshot-local"
}
}
// Android project is also using this library, so java version cannot be 1.8
sourceCompatibility = 1.7
targetCompatibility = 1.7
publishing {
publications {
mavenJava(MavenPublication) {
// Set the base name of the artifacts
artifactId 'util-lib-java'
groupId group
version version
from components.java
}
}
}
artifactory {
contextUrl = "${artifactory_contextUrl}" //The base Artifactory URL if not overridden by the publisher/resolver
publish {
repository {
if ( project.version.endsWith('-SNAPSHOT') ) {
repoKey = 'libs-snapshot-local'
} else {
repoKey = 'libs-release-local'
}
username = "${artifactory_user}"
password = "${artifactory_password}"
maven = true
}
defaults {
publications ('mavenJava')
}
}
}
and the top-level build.gradle looks like:
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:2.1.3'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
version = '1.0'
group = 'com.companyname'
repositories {
jcenter()
}
}
We're using gradle-2.14.1-bin.zip wrapper.

What am I missing here? This issue don't help me

Answer 1

Should be noted for folks stumbling across this issue that it should be resolved with the latest release: 4.4.10
https://github.com/JFrogDev/build-info/issues/101

Answer 2

For publishing you have to remove this lines in you gradle.properties or local.properties:
org.gradle.configureondemand=true
org.gradle.daemon=true
Also you have to add this in the main build.gradle file.
allprojects {
apply plugin: 'com.jfrog.artifactory'
...
}
After that the publishing should be work.
