gradle-bintray-plugin Plugin [id: 'com.jfrog.bintray', version: '1.+'] was not found

Question

I'm trying to use the gradle plugin gradle-bintray-plugin.

Currently using Gradle 4.4

Following the tutorial in the github page I should add the plugin in this way:

plugins {
    ...
    id "com.jfrog.bintray" version "1.+"
}

I'm receiving this error message and not being able to continue:

Plugin [id: 'com.jfrog.bintray', version: '1.+'] was not found in any of the following sources:

• Gradle Core Plugins (plugin is not in 'org.gradle' namespace)
• Plugin Repositories (dynamic plugin versions are not supported) Open File

Answer 1

Dynamic versions were maybe authorized in the past for the plugins block (as the tutorial gives it as an example) but now it's forbidden

if (versionSelectorScheme.parseSelector(markerVersion).isDynamic()) {
    result.notFound(SOURCE_NAME, "dynamic plugin versions are not supported");
    return;
}

But it's not the case for the old buildscript way and the below code is working fine with Gradle 4.10

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.jfrog.bintray.gradle:gradle-bintray-plugin:1.+'
    }
}

Answer 2

I just find out the solution. Looks like it just works specifying the exact version that you want to use.

So changing this:

plugins {
    ...
    id "com.jfrog.bintray" version "1.+"
}

To this:

plugins {
    ...
    id "com.jfrog.bintray" version "1.8.4" // exact version!
}

Now Works!
