title: Gradle plugin dependency exists but isn't found during the build
body: <p>It seems like what I have is correct, but Gradle is still not finding the plugin.</p>
  
  <p>My plugins clause looks like:</p>
  
  <pre><code>plugins {
      id "io.codearte.nexus-staging" version "0.8.0"
  }
  </code></pre>
  
  <p>The build error looks like:</p>
  
  <pre><code>FAILURE: Build failed with an exception.
  
  * Where:
  Build file '/home/local/MAGICLEAP/doprea/development/java/JenkinsPipelineUnit-1.1/build.gradle' line: 4
  
  * What went wrong:
  Plugin [id: 'io.codearte.nexus-staging', version: '0.8.0'] was not found in any of the following sources:
  
  - Gradle Core Plugins (plugin is not in 'org.gradle' namespace)
  - Plugin Repositories (could not resolve plugin artifact 'io.codearte.nexus-staging:io.codearte.nexus-staging.gradle.plugin:0.8.0')
    Searched in the following repositories:
      Gradle Central Plugin Repository
  </code></pre>
  
  <p>However, the CR appears to have it:</p>
  
  <p><a href="https://plugins.gradle.org/plugin/io.codearte.nexus-staging/0.8.0" rel="noreferrer">https://plugins.gradle.org/plugin/io.codearte.nexus-staging/0.8.0</a></p>
  
  <p>..and the dependency clause provided there is identical to what I already have.</p>
  
  <p>Am I missing something?</p>
