Gradle script not able to resolve artifactory - gradle

Question

I am using Gradle to access the Artifactory. Artifactory has the particular dependencies but somehow gradle is not able to send any request to Artifactory. Even I tried to clean the cache and run the gradle build command to fetch the file. But I didn't get any success. By gradle.build file is as following.
buildscript {
repositories {
maven { url 'http://repo.jfrog.org/artifactory/gradle-plugins' }
}
dependencies {
classpath(group: 'org.jfrog.buildinfo', name: 'build-info-extractor-gradle', version: '2.0.12')
}
}
apply plugin: 'maven'
apply plugin: 'artifactory'
apply plugin: 'java'
repositories {
maven {
url 'http://artifactory/repo'
}
}
group = 'com.locationlabs'
version = '1.1'
artifacts {
archives file("${project.name}-${project.version}-jstest.txt")
}
artifactory {
contextUrl = 'http://artifactory'
publish {
repository {
repoKey = 'autotest'
username = 'rakesh.kumar'
password = 'password'
}
defaults {
publishBuildInfo = true
publishArtifacts = true
publishPom = true
publishIvy = false
}
}
}
artifactoryPublish {
publishConfigs('archives')
}
dependencies {
compile group: 'com.locationlabs', name: 'gradletest', version: '1.0', classifier: 'jstest', ext: 'txt'
}
Whenever I run the gradle script it fails with the following exception and stacktrace.
akesh.kumar#rakesh:~/automation/gradletest$ gradle build --stacktrace
:compileJava

BUILD FAILED
One very strange thing is that the same script file works on the other machine but doesn't work on mine even though the other machine has the same configuration and setup.
I tried to search on internet but couldn't get any help.
Any kind of help is greatly appreciated here.

Answer 1

I have seen the very same NPE yesterday after I tried to change my project name inside gradle.settings (rootProject.name = 'something'). When I delete this line from gradle.settings, the exception disappears.
After some investigation and with the help of http://forums.gradle.org/gradle/topics/how_to_get_the_latest_integration_version_number I finally found out that the reason is a sort of circular dependency, when my project depended on some module that transitively depends back on a module with the same group and project names as the "current" project.
Might this be your case? What is the name of your project? And what are the dependencies of gradletest? Please check whether your referenced gradletest module does not depend on your project. Or, if your project itself is named gradletest, that would definitely explain the error.
